    Coordination of meiotic recombination, pairing, and synapsis by PHS1 (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-06
    Description: Pairing, synapsis, and recombination are prerequisites for accurate chromosome segregation in meiosis. The phs1 gene in maize is required for pairing to occur between homologous chromosomes. In the phs1 mutant, homologous chromosome synapsis is completely replaced by synapsis between nonhomologous partners. The phs1 gene is also required for installation of the meiotic recombination machinery on chromosomes, as the mutant almost completely lacks chromosomal foci of the recombination protein RAD51. Thus, in the phs1 mutant, synapsis is uncoupled from recombination and pairing. The protein encoded by the phs1 gene likely acts in a multistep process to coordinate pairing, recombination, and synapsis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pawlowski, Wojciech P -- Golubovskaya, Inna N -- Timofejeva, Ljudmilla -- Meeley, Robert B -- Sheridan, William F -- Cande, W Zacheus -- New York, N.Y. -- Science. 2004 Jan 2;303(5654):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720, USA. wpawlows@nature.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14704428" target="_blank"〉PubMed〈/a〉

    Uridine addition after microRNA-directed cleavage (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-11-06
    Description: One of the important roles of microRNA (miRNA) is to direct the cleavage of messenger RNA (mRNA). However, the mechanisms of decay of the cleaved mRNA products is not well understood. We show that miRNA-directed cleavage products in organisms as diverse as Arabidopsis, mouse, and Epstein-Barr virus have at their 3' ends a stretch (1 to 24 nucleotides) of oligouridine posttranscriptionally added downstream of the cleavage site. This 3' uridine addition, as shown for Arabidopsis, is correlated with decapping and 5' shortening of the cleaved products, suggesting a mechanistic step in the miRNA-directed mRNA decay mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Binzhang -- Goodman, Howard M -- New York, N.Y. -- Science. 2004 Nov 5;306(5698):997.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, and Department of Molecular Biology, Massachusetts General Hospital, 50 Blossom Street, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15528436" target="_blank"〉PubMed〈/a〉

    Living with the past: evolution, development, and patterns of disease (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-09-18
    Description: Epidemiological observations have led to the hypothesis that the risk of developing some chronic noncommunicable diseases in adulthood is influenced not only by genetic and adult life-style factors but also by environmental factors acting in early life. Research in evolutionary biology, developmental biology, and animal and human physiology provides support for this idea and suggests that environmental processes influencing the propensity to disease in adulthood operate during the periconceptual, fetal, and infant phases of life. This "developmental origins of health and disease" concept may have important biological, medical, and socioeconomic implications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gluckman, Peter D -- Hanson, Mark A -- New York, N.Y. -- Science. 2004 Sep 17;305(5691):1733-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Liggins Institute, University of Auckland and National Research Centre for Growth and Development, 2-6 Park Avenue, Grafton, Private Bag 92019, Auckland, New Zealand. pd.gluckman@auckland.ac.nz〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15375258" target="_blank"〉PubMed〈/a〉

    Mouse brain organization revealed through direct genome-scale TF expression analysis (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-25
    Description: In the developing brain, transcription factors (TFs) direct the formation of a diverse array of neurons and glia. We identifed 1445 putative TFs in the mouse genome. We used in situ hybridization to map the expression of over 1000 of these TFs and TF-coregulator genes in the brains of developing mice. We found that 349 of these genes showed restricted expression patterns that were adequate to describe the anatomical organization of the brain. We provide a comprehensive inventory of murine TFs and their expression patterns in a searchable brain atlas database.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, Paul A -- Fu, Hui -- Luo, Ping -- Zhao, Qing -- Yu, Jing -- Ferrari, Annette -- Tenzen, Toyoaki -- Yuk, Dong-In -- Tsung, Eric F -- Cai, Zhaohui -- Alberta, John A -- Cheng, Le-Ping -- Liu, Yang -- Stenman, Jan M -- Valerius, M Todd -- Billings, Nathan -- Kim, Haesun A -- Greenberg, Michael E -- McMahon, Andrew P -- Rowitch, David H -- Stiles, Charles D -- Ma, Qiufu -- New York, N.Y. -- Science. 2004 Dec 24;306(5705):2255-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15618518" target="_blank"〉PubMed〈/a〉

    Structure of the uncleaved human H1 hemagglutinin from the extinct 1918 influenza virus (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: The 1918 "Spanish" influenza pandemic represents the largest recorded outbreak of any infectious disease. The crystal structure of the uncleaved precursor of the major surface antigen of the extinct 1918 virus was determined at 3.0 angstrom resolution after reassembly of the hemagglutinin gene from viral RNA fragments preserved in 1918 formalin-fixed lung tissues. A narrow avian-like receptor-binding site, two previously unobserved histidine patches, and a less exposed surface loop at the cleavage site that activates viral membrane fusion reveal structural features primarily found in avian viruses, which may have contributed to the extraordinarily high infectivity and mortality rates observed during 1918.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, James -- Corper, Adam L -- Basler, Christopher F -- Taubenberger, Jeffery K -- Palese, Peter -- Wilson, Ian A -- AI058113/AI/NIAID NIH HHS/ -- AI42266/AI/NIAID NIH HHS/ -- AI50619/AI/NIAID NIH HHS/ -- CA55896/CA/NCI NIH HHS/ -- P50-GM 62411/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1866-70.

    Lacticin 481: in vitro reconstitution of lantibiotic synthetase activity (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-31
    Description: The lantibiotic lacticin 481 is synthesized on ribosomes as a prepeptide (LctA) and posttranslationally modified to its mature form. These modifications include dehydration of serines and threonines, followed by intramolecular addition of cysteines to the unsaturated amino acids, which generates cyclic thioethers. This process breaks eight chemical bonds and forms six newbonds and is catalyzed by one enzyme, LctM. We have characterized the in vitro activity of LctM, which completely processed a series of LctA mutants, displaying a permissive substrate specificity that holds promise for antibiotic engineering.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, Lili -- Miller, Leah M -- Chatterjee, Champak -- Averin, Olga -- Kelleher, Neil L -- van der Donk, Wilfred A -- GM 067725/GM/NIGMS NIH HHS/ -- GM58822/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 30;303(5658):679-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Illinois at Urbana-Champaign, 600 S.

    A previously unknown maltose transporter essential for starch degradation in leaves (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-06
    Description: A previously unknown maltose transporter is essential for the conversion of starch to sucrose in Arabidopsis leaves at night. The transporter was identified by isolating two allelic mutants with high starch levels and very high maltose, an intermediate of starch breakdown. The mutations affect a gene of previously unknown function, MEX1. We show that MEX1is a maltose transporter that is unrelated to other sugar transporters. The severe mex1 phenotype demonstrates that MEX1is the predominant route of carbohydrate export from chloroplasts at night. Homologous genes in plants including rice and potato indicate that maltose export is of widespread significance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Niittyla, Totte -- Messerli, Gaelle -- Trevisan, Martine -- Chen, Jychian -- Smith, Alison M -- Zeeman, Samuel C -- New York, N.Y. -- Science. 2004 Jan 2;303(5654):87-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Metabolic Biology, John Innes Centre, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14704427" target="_blank"〉PubMed〈/a〉

    Femtomolar sensitivity of a NO sensor from Clostridium botulinum (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-09
    Description: Nitric oxide (NO) is extremely toxic to Clostridium botulinum, but its molecular targets are unknown. Here, we identify a heme protein sensor (SONO) that displays femtomolar affinity for NO. The crystal structure of the SONO heme domain reveals a previously undescribed fold and a strategically placed tyrosine residue that modulates heme-nitrosyl coordination. Furthermore, the domain architecture of a SONO ortholog cloned from Chlamydomonas reinhardtii indicates that NO signaling through cyclic guanosine monophosphate arose before the origin of multicellular eukaryotes. Our findings have broad implications for understanding bacterial responses to NO, as well as for the activation of mammalian NO-sensitive guanylyl cyclase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nioche, Pierre -- Berka, Vladimir -- Vipond, Julia -- Minton, Nigel -- Tsai, Ah-Lim -- Raman, C S -- AY343540/PHS HHS/ -- R01 AI054444/AI/NIAID NIH HHS/ -- R01 AI054444-05/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Nov 26;306(5701):1550-3.

    Population-level HIV declines and behavioral risk avoidance in Uganda (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-05-01
    Description: Uganda provides the clearest example that human immunodeficiency virus (HIV) is preventable if populations are mobilized to avoid risk. Despite limited resources, Uganda has shown a 70% decline in HIV prevalence since the early 1990s, linked to a 60% reduction in casual sex. The response in Uganda appears to be distinctively associated with communication about acquired immunodeficiency syndrome (AIDS) through social networks. Despite substantial condom use and promotion of biomedical approaches, other African countries have shown neither similar behavioral responses nor HIV prevalence declines of the same scale. The Ugandan success is equivalent to a vaccine of 80% effectiveness. Its replication will require changes in global HIV/AIDS intervention policies and their evaluation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoneburner, Rand L -- Low-Beer, Daniel -- New York, N.Y. -- Science. 2004 Apr 30;304(5671):714-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Population Health Evaluation Unit, Cambridge University, Cambridge, UK. randstoneburner@netzero.net〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15118157" target="_blank"〉PubMed〈/a〉

    Description: We report that Id knockout mouse embryos display multiple cardiac defects, but mid-gestation lethality is rescued by the injection of 15 wild-type embryonic stem (ES) cells into mutant blastocysts. Myocardial markers altered in Id mutant cells are restored to normal throughout the chimeric myocardium. Intraperitoneal injection of ES cells into female mice before conception also partially rescues the cardiac phenotype with no incorporation of ES cells. Insulin-like growth factor 1, a long-range secreted factor, in combination with WNT5a, a locally secreted factor, likely account for complete reversion of the cardiac phenotype. Thus, ES cells have the potential to reverse congenital defects through Id-dependent local and long-range effects in a mammalian embryo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1351017/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1351017/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fraidenraich, Diego -- Stillwell, Elizabeth -- Romero, Elizabeth -- Wilkes, David -- Manova, Katia -- Basson, Craig T -- Benezra, Robert -- K01 HL076568/HL/NHLBI NIH HHS/ -- KO1HL076568/HL/NHLBI NIH HHS/ -- R01 CA107429/CA/NCI NIH HHS/ -- R01CA107429/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2004 Oct 8;306(5694):247-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Biology and Genetics Program, Department of Medicine, Weill Medical College of Cornell University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15472070" target="_blank"〉PubMed〈/a〉

    The genetic basis of singlet oxygen-induced stress responses of Arabidopsis thaliana (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-11-13
    Description: Plants under oxidative stress suffer from damages that have been interpreted as unavoidable consequences of injuries inflicted upon plants by toxic levels of reactive oxygen species (ROS). However, this paradigm needs to be modified. Inactivation of a single gene, EXECUTER1, is sufficient to abrogate stress responses of Arabidopsis thaliana caused by the release of singlet oxygen: External conditions under which these stress responses are observed and the amounts of ROS that accumulate in plants exposed to these environmental conditions do not directly cause damages. Instead, seedling lethality and growth inhibition of mature plants result from genetic programs that are activated after the release of singlet oxygen has been perceived by the plant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Daniela -- Przybyla, Dominika -- Op den Camp, Roel -- Kim, Chanhong -- Landgraf, Frank -- Lee, Keun Pyo -- Wursch, Marco -- Laloi, Christophe -- Nater, Mena -- Hideg, Eva -- Apel, Klaus -- New York, N.Y. -- Science. 2004 Nov 12;306(5699):1183-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Sciences, Plant Genetics, Swiss Federal Institute of Technology (ETH), CH-8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15539603" target="_blank"〉PubMed〈/a〉

    Plant cuticular lipid export requires an ABC transporter (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-23
    Description: A waxy protective cuticle coats all primary aerial plant tissues. Its synthesis requires extensive export of lipids from epidermal cells to the plant surface. Arabidopsis cer5 mutants had reduced stem cuticular wax loads and accumulated sheetlike inclusions in the cytoplasm of wax-secreting cells. These inclusions represented abnormal deposits of cuticular wax and resembled inclusions found in a human disorder caused by a defective peroxisomal adenosine triphosphate binding cassette (ABC) transporter. We found that the CER5 gene encodes an ABC transporter localized in the plasma membrane of epidermal cells and conclude that it is required for wax export to the cuticle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pighin, Jamie A -- Zheng, Huanquan -- Balakshin, Laura J -- Goodman, Ian P -- Western, Tamara L -- Jetter, Reinhard -- Kunst, Ljerka -- Samuels, A Lacey -- New York, N.Y. -- Science. 2004 Oct 22;306(5696):702-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, University of British Columbia (UBC), 6270 University Boulevard, Vancouver, BC V6T 1Z4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15499022" target="_blank"〉PubMed〈/a〉

    A putative Ca2+ and calmodulin-dependent protein kinase required for bacterial and fungal symbioses (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Legumes can enter into symbiotic relationships with both nitrogen-fixing bacteria (rhizobia) and mycorrhizal fungi. Nodulation by rhizobia results from a signal transduction pathway induced in legume roots by rhizobial Nod factors. DMI3, a Medicago truncatula gene that acts immediately downstream of calcium spiking in this signaling pathway and is required for both nodulation and mycorrhizal infection, has high sequence similarity to genes encoding calcium and calmodulin-dependent protein kinases (CCaMKs). This indicates that calcium spiking is likely an essential component of the signaling cascade leading to nodule development and mycorrhizal infection, and sheds light on the biological role of plant CCaMKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, Julien -- Bres, Cecile -- Geurts, Rene -- Chalhoub, Boulos -- Kulikova, Olga -- Duc, Gerard -- Journet, Etienne-Pascal -- Ane, Jean-Michel -- Lauber, Emmanuelle -- Bisseling, Ton -- Denarie, Jean -- Rosenberg, Charles -- Debelle, Frederic -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1361-4.

    A membrane-anchored protein kinase involved in Brassica self-incompatibility signaling (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-03-06
    Description: Self-incompatibility (SI) response in Brassica is initiated by haplotype-specific interactions between the pollen-borne ligand S locus protein 11/SCR and its stigmatic S receptor kinase, SRK. This binding induces autophosphorylation of SRK, which is then thought to trigger a signaling cascade that leads to self-pollen rejection. A recessive mutation of the modifier (m) gene eliminates the SI response in stigma. Positional cloning of M has revealed that it encodes a membrane-anchored cytoplasmic serine/threonine protein kinase, designated M locus protein kinase (MLPK). Transient expression of MLPK restores the ability of mm papilla cells to reject self-pollen, suggesting that MLPK is a positive mediator of Brassica SI signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murase, Kohji -- Shiba, Hiroshi -- Iwano, Megumi -- Che, Fang-Sik -- Watanabe, Masao -- Isogai, Akira -- Takayama, Seiji -- New York, N.Y. -- Science. 2004 Mar 5;303(5663):1516-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biological Sciences, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma 630-0101, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15001779" target="_blank"〉PubMed〈/a〉

    The wheat VRN2 gene is a flowering repressor down-regulated by vernalization (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-03-16
    Description: Plants with a winter growth habit flower earlier when exposed for several weeks to cold temperatures, a process called vernalization. We report here the positional cloning of the wheat vernalization gene VRN2, a dominant repressor of flowering that is down-regulated by vernalization. Loss of function of VRN2, whether by natural mutations or deletions, resulted in spring lines, which do not require vernalization to flower. Reduction of the RNA level of VRN2 by RNA interference accelerated the flowering time of transgenic winter-wheat plants by more than a month.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737501/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yan, Liuling -- Loukoianov, Artem -- Blechl, Ann -- Tranquilli, Gabriela -- Ramakrishna, Wusirika -- SanMiguel, Phillip -- Bennetzen, Jeffrey L -- Echenique, Viviana -- Dubcovsky, Jorge -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2004 Mar 12;303(5664):1640-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Agronomy and Range Science, University of California, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15016992" target="_blank"〉PubMed〈/a〉

    The PIDDosome, a protein complex implicated in activation of caspase-2 in response to genotoxic stress (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-10
    Description: Apoptosis is triggered by activation of initiator caspases upon complex-mediated clustering of the inactive zymogen, as occurs in the caspase-9-activating apoptosome complex. Likewise, caspase-2, which is involved in stress-induced apoptosis, is recruited into a large protein complex, the molecular composition of which remains elusive. We show that activation of caspase-2 occurs in a complex that contains the death domain-containing protein PIDD, whose expression is induced by p53, and the adaptor protein RAIDD. Increased PIDD expression resulted in spontaneous activation of caspase-2 and sensitization to apoptosis by genotoxic stimuli. Because PIDD functions in p53-mediated apoptosis, the complex assembled by PIDD and caspase-2 is likely to regulate apoptosis induced by genotoxins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tinel, Antoine -- Tschopp, Jurg -- New York, N.Y. -- Science. 2004 May 7;304(5672):843-6.

    Details
    Publication Date: 2004-02-21
    Description: Mycobacteria have low-permeability outer membranes that render them resistant to most antibiotics. Hydrophilic nutrients can enter by way of transmembrane-channel proteins called porins. An x-ray analysis of the main porin from Mycobacterium smegmatis, MspA, revealed a homooctameric goblet-like conformation with a single central channel. This is the first structure of a mycobacterial outer-membrane protein. No structure-related protein was found in the Protein Data Bank. MspA contains two consecutive beta barrels with nonpolar outer surfaces that form a ribbon around the porin, which is too narrow to fit the thickness of the mycobacterial outer membrane in contemporary models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faller, Michael -- Niederweis, Michael -- Schulz, Georg E -- New York, N.Y. -- Science. 2004 Feb 20;303(5661):1189-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Organische Chemie und Biochemie, Albert-Ludwigs-Universitat, Albertstrasse 21, 79104 Freiburg im Breisgau, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14976314" target="_blank"〉PubMed〈/a〉

    Publication Date: 2004-12-25
    Description: The position-dependent specification of root epidermal cells in Arabidopsis provides an elegant paradigm for cell patterning during development. Here, we describe a new gene, SCRAMBLED (SCM), required for cells to appropriately interpret their location within the developing root epidermis. SCM encodes a receptor-like kinase protein with a predicted extracellular domain of six leucine-rich repeats and an intracellular serine-threonine kinase domain. SCM regulates the expression of the GLABRA2, CAPRICE, WEREWOLF, and ENHANCER OF GLABRA3 transcription factor genes that define the cell fates. Further, the SCM gene is expressed throughout the developing root. Therefore, SCM likely enables developing epidermal cells to detect positional cues and establish an appropriate cell-type pattern.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwak, Su-Hwan -- Shen, Ronglai -- Schiefelbein, John -- New York, N.Y. -- Science. 2005 Feb 18;307(5712):1111-3.

    Identification of virus-encoded microRNAs (2004)

    Publication Date: 2004-05-01
    Description: RNA silencing processes are guided by small RNAs that are derived from double-stranded RNA. To probe for function of RNA silencing during infection of human cells by a DNA virus, we recorded the small RNA profile of cells infected by Epstein-Barr virus (EBV). We show that EBV expresses several microRNA (miRNA) genes. Given that miRNAs function in RNA silencing pathways either by targeting messenger RNAs for degradation or by repressing translation, we identified viral regulators of host and/or viral gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfeffer, Sebastien -- Zavolan, Mihaela -- Grasser, Friedrich A -- Chien, Minchen -- Russo, James J -- Ju, Jingyue -- John, Bino -- Enright, Anton J -- Marks, Debora -- Sander, Chris -- Tuschl, Thomas -- R01-GM068476-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 30;304(5671):734-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of RNA Molecular Biology, The Rockefeller University, 1230 York Avenue, Box 186, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15118162" target="_blank"〉PubMed〈/a〉

    Human De-etiolated-1 regulates c-Jun by assembling a CUL4A ubiquitin ligase (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-24
    Description: Arabidopsis thaliana De-etiolated-1 (AtDET1) is a highly conserved protein, with orthologs in vertebrate and invertebrate organisms. AtDET1 negatively regulates photomorphogenesis, but its biochemical mechanism and function in other species are unknown. We report that human DET1 (hDET1) promotes ubiquitination and degradation of the proto-oncogenic transcription factor c-Jun by assembling a multisubunit ubiquitin ligase containing DNA Damage Binding Protein-1 (DDB1), cullin 4A (CUL4A), Regulator of Cullins-1 (ROC1), and constitutively photomorphogenic-1. Ablation of any subunit by RNA interference stabilized c-Jun and increased c-Jun-activated transcription. These findings characterize a c-Jun ubiquitin ligase and define a specific function for hDET1 in mammalian cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wertz, Ingrid E -- O'Rourke, Karen M -- Zhang, Zemin -- Dornan, David -- Arnott, David -- Deshaies, Raymond J -- Dixit, Vishva M -- GM065997/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1371-4.

    Reverse methanogenesis: testing the hypothesis with environmental genomics (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-09-09
    Description: Microbial methane consumption in anoxic sediments significantly impacts the global environment by reducing the flux of greenhouse gases from ocean to atmosphere. Despite its significance, the biological mechanisms controlling anaerobic methane oxidation are not well characterized. One current model suggests that relatives of methane-producing Archaea developed the capacity to reverse methanogenesis and thereby to consume methane to produce cellular carbon and energy. We report here a test of the "reverse-methanogenesis" hypothesis by genomic analyses of methane-oxidizing Archaea from deep-sea sediments. Our results show that nearly all genes typically associated with methane production are present in one specific group of archaeal methanotrophs. These genome-based observations support previous hypotheses and provide an informed foundation for metabolic modeling of anaerobic methane oxidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hallam, Steven J -- Putnam, Nik -- Preston, Christina M -- Detter, John C -- Rokhsar, Daniel -- Richardson, Paul M -- DeLong, Edward F -- New York, N.Y. -- Science. 2004 Sep 3;305(5689):1457-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15353801" target="_blank"〉PubMed〈/a〉

    Dendrite development regulated by CREST, a calcium-regulated transcriptional activator (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-13
    Description: The lasting effects of neuronal activity on brain development involve calcium-dependent gene expression. Using a strategy called transactivator trap, we cloned a calcium-responsive transactivator called CREST (for calcium-responsive transactivator). CREST is a SYT-related nuclear protein that interacts with adenosine 3',5'-monophosphate (cAMP) response element-binding protein (CREB)-binding protein (CBP) and is expressed in the developing brain. Mice that have a targeted disruption of the crest gene are viable but display defects in cortical and hippocampal dendrite development. Cortical neurons from crest mutant mice are compromised in calcium-dependent dendritic growth. Thus, calcium activation of CREST-mediated transcription helps regulate neuronal morphogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aizawa, Hiroyuki -- Hu, Shu-Ching -- Bobb, Kathryn -- Balakrishnan, Karthik -- Ince, Gulayse -- Gurevich, Inga -- Cowan, Mitra -- Ghosh, Anirvan -- MH60598/MH/NIMH NIH HHS/ -- NS39993/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 9;303(5655):197-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14716005" target="_blank"〉PubMed〈/a〉

    Host-parasite coevolutionary conflict between Arabidopsis and downy mildew (2004)

    Details
    Publication Date: 2004-12-14
    Description: Plants are constantly exposed to attack by an array of diverse pathogens but lack a somatically adaptive immune system. In spite of this, natural plant populations do not often suffer destructive disease epidemics. Elucidating how allelic diversity within plant genes that function to detect pathogens (resistance genes) counteracts changing structures of pathogen genes required for host invasion (pathogenicity effectors) is critical to our understanding of the dynamics of natural plant populations. The RPP13 resistance gene is the most polymorphic gene analyzed to date in the model plant Arabidopsis thaliana. Here we report the cloning of the avirulence gene, ATR13, that triggers RPP13-mediated resistance, and we show that it too exhibits extreme levels of amino acid polymorphism. Evidence of diversifying selection visible in both components suggests that the host and pathogen may be locked in a coevolutionary conflict at these loci, where attempts to evade host resistance by the pathogen are matched by the development of new detection capabilities by the host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, Rebecca L -- Bittner-Eddy, Peter D -- Grenville-Briggs, Laura J -- Meitz, Julia C -- Rehmany, Anne P -- Rose, Laura E -- Beynon, Jim L -- New York, N.Y. -- Science. 2004 Dec 10;306(5703):1957-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Warwick, HRI University of Warwick, Wellesbourne, Warwick, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15591208" target="_blank"〉PubMed〈/a〉

    Ciliary photoreceptors with a vertebrate-type opsin in an invertebrate brain (2004)

    Publication Date: 2004-10-30
    Description: For vision, insect and vertebrate eyes use rhabdomeric and ciliary photoreceptor cells, respectively. These cells show distinct architecture and transduce the light signal by different phototransductory cascades. In the marine rag-worm Platynereis, we find both cell types: rhabdomeric photoreceptor cells in the eyes and ciliary photoreceptor cells in the brain. The latter use a photopigment closely related to vertebrate rod and cone opsins. Comparative analysis indicates that both types of photoreceptors, with distinct opsins, coexisted in Urbilateria, the last common ancestor of insects and vertebrates, and sheds new light on vertebrate eye evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arendt, Detlev -- Tessmar-Raible, Kristin -- Snyman, Heidi -- Dorresteijn, Adriaan W -- Wittbrodt, Joachim -- New York, N.Y. -- Science. 2004 Oct 29;306(5697):869-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Biology Department, European Molecular Biology Laboratory, Meyerhofstrasse 1, 69012 Heidelberg, Germany. detlev.arendt@embl.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15514158" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2004-03-06
    Description: Toll-like receptors (TLRs) recognize molecular patterns displayed by microorganisms, and their subsequent activation leads to the transcription of appropriate host-defense genes. Here we report the cloning and characterization of a member of the mammalian TLR family, TLR11, that displays a distinct pattern of expression in macrophages and liver, kidney, and bladder epithelial cells. Cells expressing TLR11 fail to respond to known TLR ligands but instead respond specifically to uropathogenic bacteria. Mice lacking TLR11 are highly susceptible to infection of the kidneys by uropathogenic bacteria, indicating a potentially important role for TLR11 in preventing infection of internal organs of the urogenital system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Dekai -- Zhang, Guolong -- Hayden, Matthew S -- Greenblatt, Matthew B -- Bussey, Crystal -- Flavell, Richard A -- Ghosh, Sankar -- GM07205/GM/NIGMS NIH HHS/ -- R01-AI59440/AI/NIAID NIH HHS/ -- R37-AI33443/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 5;303(5663):1522-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Immunobiology and Department of Molecular Biophysics and Biochemistry, Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15001781" target="_blank"〉PubMed〈/a〉

    Medicago truncatula DMI1 required for bacterial and fungal symbioses in legumes (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Legumes form symbiotic associations with both mycorrhizal fungi and nitrogen-fixing soil bacteria called rhizobia. Several of the plant genes required for transduction of rhizobial signals, the Nod factors, are also necessary for mycorrhizal symbiosis. Here, we describe the cloning and characterization of one such gene from the legume Medicago truncatula. The DMI1 (does not make infections) gene encodes a novel protein with low global similarity to a ligand-gated cation channel domain of archaea. The protein is highly conserved in angiosperms and ancestral to land plants. We suggest that DMI1 represents an ancient plant-specific innovation, potentially enabling mycorrhizal associations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ane, Jean-Michel -- Kiss, Gyorgy B -- Riely, Brendan K -- Penmetsa, R Varma -- Oldroyd, Giles E D -- Ayax, Celine -- Levy, Julien -- Debelle, Frederic -- Baek, Jong-Min -- Kalo, Peter -- Rosenberg, Charles -- Roe, Bruce A -- Long, Sharon R -- Denarie, Jean -- Cook, Douglas R -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1364-7.

    Enrichment of gene-coding sequences in maize by genome filtration (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-20
    Description: Approximately 80% of the maize genome comprises highly repetitive sequences interspersed with single-copy, gene-rich sequences, and standard genome sequencing strategies are not readily adaptable to this type of genome. Methodologies that enrich for genic sequences might more rapidly generate useful results from complex genomes. Equivalent numbers of clones from maize selected by techniques called methylation filtering and High C0t selection were sequenced to generate approximately 200,000 reads (approximately 132 megabases), which were assembled into contigs. Combination of the two techniques resulted in a sixfold reduction in the effective genome size and a fourfold increase in the gene identification rate in comparison to a nonenriched library.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitelaw, C A -- Barbazuk, W B -- Pertea, G -- Chan, A P -- Cheung, F -- Lee, Y -- Zheng, L -- van Heeringen, S -- Karamycheva, S -- Bennetzen, J L -- SanMiguel, P -- Lakey, N -- Bedell, J -- Yuan, Y -- Budiman, M A -- Resnick, A -- Van Aken, S -- Utterback, T -- Riedmuller, S -- Williams, M -- Feldblyum, T -- Schubert, K -- Beachy, R -- Fraser, C M -- Quackenbush, J -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2118-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684821" target="_blank"〉PubMed〈/a〉

    Description: We collected and completely sequenced 28,469 full-length complementary DNA clones from Oryza sativa L. ssp. japonica cv. Nipponbare. Through homology searches of publicly available sequence data, we assigned tentative protein functions to 21,596 clones (75.86%). Mapping of the cDNA clones to genomic DNA revealed that there are 19,000 to 20,500 transcription units in the rice genome. Protein informatics analysis against the InterPro database revealed the existence of proteins presented in rice but not in Arabidopsis. Sixty-four percent of our cDNAs are homologous to Arabidopsis proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice Full-Length cDNA Consortium -- National Institute of Agrobiological Sciences Rice Full-Length cDNA Project Team -- Kikuchi, Shoshi -- Satoh, Kouji -- Nagata, Toshifumi -- Kawagashira, Nobuyuki -- Doi, Koji -- Kishimoto, Naoki -- Yazaki, Junshi -- Ishikawa, Masahiro -- Yamada, Hitomi -- Ooka, Hisako -- Hotta, Isamu -- Kojima, Keiichi -- Namiki, Takahiro -- Ohneda, Eisuke -- Yahagi, Wataru -- Suzuki, Kohji -- Li, Chao Jie -- Ohtsuki, Kenji -- Shishiki, Toru -- Foundation of Advancement of International Science Genome Sequencing & Analysis Group -- Otomo, Yasuhiro -- Murakami, Kazuo -- Iida, Yoshiharu -- Sugano, Sumio -- Fujimura, Tatsuto -- Suzuki, Yutaka -- Tsunoda, Yuki -- Kurosaki, Takashi -- Kodama, Takeko -- Masuda, Hiromi -- Kobayashi, Michie -- Xie, Quihong -- Lu, Min -- Narikawa, Ryuya -- Sugiyama, Akio -- Mizuno, Kouichi -- Yokomizo, Satoko -- Niikura, Junko -- Ikeda, Rieko -- Ishibiki, Junya -- Kawamata, Midori -- Yoshimura, Akemi -- Miura, Junichirou -- Kusumegi, Takahiro -- Oka, Mitsuru -- Ryu, Risa -- Ueda, Mariko -- Matsubara, Kenichi -- RIKEN -- Kawai, Jun -- Carninci, Piero -- Adachi, Jun -- Aizawa, Katsunori -- Arakawa, Takahiro -- Fukuda, Shiro -- Hara, Ayako -- Hashizume, Wataru -- Hayatsu, Norihito -- Imotani, Koichi -- Ishii, Yoshiyuki -- Itoh, Masayoshi -- Kagawa, Ikuko -- Kondo, Shinji -- Konno, Hideaki -- Miyazaki, Ai -- Osato, Naoki -- Ota, Yoshimi -- Saito, Rintaro -- Sasaki, Daisuke -- Sato, Kenjiro -- Shibata, Kazuhiro -- Shinagawa, Akira -- Shiraki, Toshiyuki -- Yoshino, Masayasu -- Hayashizaki, Yoshihide -- Yasunishi, Ayako -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):376-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, National Institute of Agrobiological Sciences, 2-1-2 Kannon-dai, Tsukuba, Ibaraki 305-8602, Japan. skikuchi@nias.affrc.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12869764" target="_blank"〉PubMed〈/a〉

    Derepression of BDNF transcription involves calcium-dependent phosphorylation of MeCP2 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Mutations in MeCP2, which encodes a protein that has been proposed to function as a global transcriptional repressor, are the cause of Rett syndrome (RT T), an X-linked progressive neurological disorder. Although the selective inactivation of MeCP2 in neurons is sufficient to confer a Rett-like phenotype in mice, the specific functions of MeCP2 in postmitotic neurons are not known. We find that MeCP2 binds selectively to BDNF promoter III and functions to repress expression of the BDNF gene. Membrane depolarization triggers the calcium-dependent phosphorylation and release of MeCP2 from BDNF promoter III, thereby facilitating transcription. These studies indicate that MeCP2 plays a key role in the control of neuronal activity-dependent gene regulation and suggest that the deregulation of this process may underlie the pathology of RT T.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Wen G -- Chang, Qiang -- Lin, Yingxi -- Meissner, Alexander -- West, Anne E -- Griffith, Eric C -- Jaenisch, Rudolf -- Greenberg, Michael E -- HD 18655/HD/NICHD NIH HHS/ -- NS28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):885-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593183" target="_blank"〉PubMed〈/a〉

    ARGONAUTE4 control of locus-specific siRNA accumulation and DNA and histone methylation (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-11
    Description: Proteins of the ARGONAUTE family are important in diverse posttranscriptional RNA-mediated gene-silencing systems as well as in transcriptional gene silencing in Drosophila and fission yeast and in programmed DNA elimination in Tetrahymena. We cloned ARGONAUTE4 (AGO4) from a screen for mutants that suppress silencing of the Arabidopsis SUPERMAN (SUP) gene. The ago4-1 mutant reactivated silent SUP alleles and decreased CpNpG and asymmetric DNA methylation as well as histone H3 lysine-9 methylation. In addition, ago4-1 blocked histone and DNA methylation and the accumulation of 25-nucleotide small interfering RNAs (siRNAs) that correspond to the retroelement AtSN1. These results suggest that AGO4 and long siRNAs direct chromatin modifications, including histone methylation and non-CpG DNA methylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zilberman, Daniel -- Cao, Xiaofeng -- Jacobsen, Steven E -- GM07185/GM/NIGMS NIH HHS/ -- GM60398/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jan 31;299(5607):716-9.

    Modification of ocular defects in mouse developmental glaucoma models by tyrosinase (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-08
    Description: Mutations in the cytochrome P450 family 1, subfamily B, polypeptide 1 (CYP1B1) gene are a common cause of human primary congenital glaucoma (PCG). Here we show that Cyp1b1-/- mice have ocular drainage structure abnormalities resembling those reported in human PCG patients. Using Cyp1b1-/- mice, we identified the tyrosinase gene (Tyr) as a modifier of the drainage structure phenotype, with Tyr deficiency increasing the magnitude of dysgenesis. The severe dysgenesis in eyes lacking both CYP1B1 and TYR was alleviated by administration of the tyrosinase product dihydroxyphenylalanine (l-dopa). Tyr also modified the drainage structure dysgenesis in mice with a mutant Foxc1 gene, which is also involved in PCG. These experiments raise the possibility that a tyrosinase/l-dopa pathway modifies human PCG, which could open new therapeutic avenues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Libby, Richard T -- Smith, Richard S -- Savinova, Olga V -- Zabaleta, Adriana -- Martin, Janice E -- Gonzalez, Frank J -- John, Simon W M -- CA34196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2003 Mar 7;299(5612):1578-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12624268" target="_blank"〉PubMed〈/a〉

    Empirical analysis of transcriptional activity in the Arabidopsis genome (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Functional analysis of a genome requires accurate gene structure information and a complete gene inventory. A dual experimental strategy was used to verify and correct the initial genome sequence annotation of the reference plant Arabidopsis. Sequencing full-length cDNAs and hybridizations using RNA populations from various tissues to a set of high-density oligonucleotide arrays spanning the entire genome allowed the accurate annotation of thousands of gene structures. We identified 5817 novel transcription units, including a substantial amount of antisense gene transcription, and 40 genes within the genetically defined centromeres. This approach resulted in completion of approximately 30% of the Arabidopsis ORFeome as a resource for global functional experimentation of the plant proteome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamada, Kayoko -- Lim, Jun -- Dale, Joseph M -- Chen, Huaming -- Shinn, Paul -- Palm, Curtis J -- Southwick, Audrey M -- Wu, Hank C -- Kim, Christopher -- Nguyen, Michelle -- Pham, Paul -- Cheuk, Rosa -- Karlin-Newmann, George -- Liu, Shirley X -- Lam, Bao -- Sakano, Hitomi -- Wu, Troy -- Yu, Guixia -- Miranda, Molly -- Quach, Hong L -- Tripp, Matthew -- Chang, Charlie H -- Lee, Jeong M -- Toriumi, Mitsue -- Chan, Marie M H -- Tang, Carolyn C -- Onodera, Courtney S -- Deng, Justine M -- Akiyama, Kenji -- Ansari, Yasser -- Arakawa, Takahiro -- Banh, Jenny -- Banno, Fumika -- Bowser, Leah -- Brooks, Shelise -- Carninci, Piero -- Chao, Qimin -- Choy, Nathan -- Enju, Akiko -- Goldsmith, Andrew D -- Gurjal, Mani -- Hansen, Nancy F -- Hayashizaki, Yoshihide -- Johnson-Hopson, Chanda -- Hsuan, Vickie W -- Iida, Kei -- Karnes, Meagan -- Khan, Shehnaz -- Koesema, Eric -- Ishida, Junko -- Jiang, Paul X -- Jones, Ted -- Kawai, Jun -- Kamiya, Asako -- Meyers, Cristina -- Nakajima, Maiko -- Narusaka, Mari -- Seki, Motoaki -- Sakurai, Tetsuya -- Satou, Masakazu -- Tamse, Racquel -- Vaysberg, Maria -- Wallender, Erika K -- Wong, Cecilia -- Yamamura, Yuki -- Yuan, Shiaulou -- Shinozaki, Kazuo -- Davis, Ronald W -- Theologis, Athanasios -- Ecker, Joseph R -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):842-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Gene Expression Center, Albany, CA 94710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593172" target="_blank"〉PubMed〈/a〉

    Publication Date: 2003-04-19
    Description: Genetic analyses of permafrost and temperate sediments reveal that plant and animal DNA may be preserved for long periods, even in the absence of obvious macrofossils. In Siberia, five permafrost cores ranging from 400,000 to 10,000 years old contained at least 19 different plant taxa, including the oldest authenticated ancient DNA sequences known, and megafaunal sequences including mammoth, bison, and horse. The genetic data record a number of dramatic changes in the taxonomic diversity and composition of Beringian vegetation and fauna. Temperate cave sediments in New Zealand also yielded DNA sequences of extinct biota, including two species of ratite moa, and 29 plant taxa characteristic of the prehuman environment. Therefore, many sedimentary deposits may contain unique, and widespread, genetic records of paleoenvironments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willerslev, Eske -- Hansen, Anders J -- Binladen, Jonas -- Brand, Tina B -- Gilbert, M Thomas P -- Shapiro, Beth -- Bunce, Michael -- Wiuf, Carsten -- Gilichinsky, David A -- Cooper, Alan -- New York, N.Y. -- Science. 2003 May 2;300(5620):791-5.

    Modulating sphingolipid biosynthetic pathway rescues photoreceptor degeneration (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-15
    Description: Mutations in proteins of the Drosophila phototransduction cascade, a prototypic guanine nucleotide-binding protein-coupled receptor signaling system, lead to retinal degeneration and have been used as models to understand human degenerative disorders. Here, modulating the sphingolipid biosynthetic pathway rescued retinal degeneration in Drosophila mutants. Targeted expression of Drosophila neutral ceramidase rescued retinal degeneration in arrestin and phospholipase C mutants. Decreasing flux through the de novo sphingolipid biosynthetic pathway also suppressed degeneration in these mutants. Both genetic backgrounds modulated the endocytic machinery because they suppressed defects in a dynamin mutant. Suppression of degeneration in arrestin mutant flies expressing ceramidase correlated with a decrease in ceramide levels. Thus, enzymes of sphingolipid metabolism may be suitable targets in the therapeutic management of retinal degeneration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Acharya, Usha -- Patel, Shetal -- Koundakjian, Edmund -- Nagashima, Kunio -- Han, Xianlin -- Acharya, Jairaj K -- New York, N.Y. -- Science. 2003 Mar 14;299(5613):1740-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regulation of Cell Growth Laboratory, National Cancer Institute-Frederick, Frederick, MD 21702, USA. acharyau@mail.ncifcrf.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12637747" target="_blank"〉PubMed〈/a〉

    Positional cloning of the human quantitative trait locus underlying taste sensitivity to phenylthiocarbamide (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-22
    Description: The ability to taste the substance phenylthiocarbamide (PTC) has been widely used for genetic and anthropological studies, but genetic studies have produced conflicting results and demonstrated complex inheritance for this trait. We have identified a small region on chromosome 7q that shows strong linkage disequilibrium between single-nucleotide polymorphism (SNP) markers and PTC taste sensitivity in unrelated subjects. This region contains a single gene that encodes a member of the TAS2R bitter taste receptor family. We identified three coding SNPs giving rise to five haplotypes in this gene worldwide. These haplotypes completely explain the bimodal distribution of PTC taste sensitivity, thus accounting for the inheritance of the classically defined taste insensitivity and for 55 to 85% of the variance in PTC sensitivity. Distinct phenotypes were associated with specific haplotypes, which demonstrates that this gene has a direct influence on PTC taste sensitivity and that sequence variants at different sites interact with each other within the encoded gene product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Un-kyung -- Jorgenson, Eric -- Coon, Hilary -- Leppert, Mark -- Risch, Neil -- Drayna, Dennis -- M01-RR00064/RR/NCRR NIH HHS/ -- T32 HG00044/HG/NHGRI NIH HHS/ -- Z01-000046-04/PHS HHS/ -- New York, N.Y. -- Science. 2003 Feb 21;299(5610):1221-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute on Deafness and Other Communication Disorders, National Institutes of Health, 5 Research Court, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12595690" target="_blank"〉PubMed〈/a〉

    Conserved role of nanos proteins in germ cell development (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-30
    Description: In Drosophila, maternally supplied Nanos functions in the migration of primordial germ cells (PGCs) into the gonad; in mice, zygotic genes are involved instead. We report the cloning and the functional analyses of nanos2 and nanos3 in mice. These genes are differentially expressed in mouse PGCs. nanos2 is predominantly expressed in male germ cells, and the elimination of this gene results in a complete loss of spermatogonia. However, nanos3 is found in migrating PGCs, and the elimination of this factor results in the complete loss of germ cells in both sexes. Hence, although mice and flies differ in their mechanisms for germ cell specification, there seems to be conserved function for nanos proteins among invertebrates and vertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsuda, Masayuki -- Sasaoka, Yumiko -- Kiso, Makoto -- Abe, Kuniya -- Haraguchi, Seiki -- Kobayashi, Satoru -- Saga, Yumiko -- New York, N.Y. -- Science. 2003 Aug 29;301(5637):1239-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Mammalian Development, National Institute of Genetics, SOKENDAI, Yata 1111, Mishima, Shizuoka 411-8540, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12947200" target="_blank"〉PubMed〈/a〉

    Illuminating the circadian clock in monarch butterfly migration (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-24
    Description: Migratory monarch butterflies use a time-compensated Sun compass to navigate to their overwintering grounds in Mexico. Here, we report that constant light, which disrupts circadian clock function at both the behavioral and molecular levels in monarchs, also disrupts the time-compensated component of flight navigation. We further show that ultraviolet light is important for flight navigation but is not required for photic entrainment of circadian rhythms. Tracing these distinct light-input pathways into the brain should aid our understanding of the clock-compass mechanisms necessary for successful migration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Froy, Oren -- Gotter, Anthony L -- Casselman, Amy L -- Reppert, Steven M -- New York, N.Y. -- Science. 2003 May 23;300(5623):1303-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, University of Massachusetts Medical School, LRB-728, 364 Plantation Street, Worcester, MA 01605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12764200" target="_blank"〉PubMed〈/a〉

    Selective trafficking of non-cell-autonomous proteins mediated by NtNCAPP1 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-18
    Description: In plants, cell-to-cell communication is mediated by plasmodesmata and involves the trafficking of non-cell-autonomous proteins (NCAPs). A component in this pathway, Nicotiana tabacum NON-CELL-AUTONOMOUS PATHWAY PROTEIN1 (NtNCAPP1), was affinity purified and cloned. Protein overlay assays and in vivo studies showed that NtNCAPP1 is located on the endoplasmic reticulum at the cell periphery and displays specificity in its interaction with NCAPs. Deletion of the NtNCAPP1 amino-terminal transmembrane domain produced a dominant-negative mutant that blocked the trafficking of specific NCAPs. Transgenic tobacco plants expressing this mutant form of NtNCAPP1 and plants in which the NtNCAPP1 gene was silenced were compromised in their ability to regulate leaf and floral development. These results support a model in which NCAP delivery to plasmodesmata is both selective and regulated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Jung-Youn -- Yoo, Byung-Chun -- Rojas, Maria R -- Gomez-Ospina, Natalia -- Staehelin, L Andrew -- Lucas, William J -- GM18639/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jan 17;299(5605):392-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Plant Biology, Division of Biological Sciences, University of California, 1 Shields Avenue, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12532017" target="_blank"〉PubMed〈/a〉

    Pregnancy-stimulated neurogenesis in the adult female forebrain mediated by prolactin (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-04
    Description: Neurogenesis occurs in the olfactory system of the adult brain throughout life, in both invertebrates and vertebrates, but its physiological regulation is not understood. We show that the production of neuronal progenitors is stimulated in the forebrain subventricular zone of female mice during pregnancy and that this effect is mediated by the hormone prolactin. The progenitors then migrate to produce new olfactory interneurons, a process likely to be important for maternal behavior, because olfactory discrimination is critical for recognition and rearing of offspring. Neurogenesis occurs even in females that mate with sterile males. These findings imply that forebrain olfactory neurogenesis may contribute to adaptive behaviors in mating and pregnancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shingo, Tetsuro -- Gregg, Christopher -- Enwere, Emeka -- Fujikawa, Hirokazu -- Hassam, Rozina -- Geary, Colleen -- Cross, James C -- Weiss, Samuel -- New York, N.Y. -- Science. 2003 Jan 3;299(5603):117-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genes & Development Research Group, Department of Cell Biology and Anatomy, University of Calgary Faculty of Medicine, Calgary, Alberta, Canada T2N 4N1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12511652" target="_blank"〉PubMed〈/a〉

    Description: Alu repetitive elements can be inserted into mature messenger RNAs via a splicing-mediated process termed exonization. To understand the molecular basis and the regulation of the process of turning intronic Alus into new exons, we compiled and analyzed a data set of human exonized Alus. We revealed a mechanism that governs 3' splice-site selection in these exons during alternative splicing. On the basis of these findings, we identified mutations that activated the exonization of a silent intronic Alu.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lev-Maor, Galit -- Sorek, Rotem -- Shomron, Noam -- Ast, Gil -- New York, N.Y. -- Science. 2003 May 23;300(5623):1288-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics and Molecular Medicine, Sackler Faculty of Medicine, Tel Aviv University, Ramat Aviv 69978, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12764196" target="_blank"〉PubMed〈/a〉

    GUN4, a regulator of chlorophyll synthesis and intracellular signaling (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-08
    Description: Nuclear genes control plastid differentiation in response to developmental signals, environmental signals, and retrograde signals from plastids themselves. In return, plastids emit signals that are essential for proper expression of many nuclear photosynthetic genes. Accumulation of magnesium-protoporphyrin IX (Mg-Proto), an intermediate in chlorophyll biosynthesis, is a plastid signal that represses nuclear transcription through a signaling pathway that, in Arabidopsis, requires the GUN4 gene. GUN4 binds the product and substrate of Mg- chelatase, an enzyme that produces Mg-Proto, and activates Mg-chelatase. Thus, GUN4 participates in plastid-to-nucleus signaling by regulating Mg-Proto synthesis or trafficking.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larkin, Robert M -- Alonso, Jose M -- Ecker, Joseph R -- Chory, Joanne -- New York, N.Y. -- Science. 2003 Feb 7;299(5608):902-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, The Salk Institute for Biological Studies, 10010 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12574634" target="_blank"〉PubMed〈/a〉

    Essential role of Fkbp6 in male fertility and homologous chromosome pairing in meiosis (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-24
    Description: Meiosis is a critical stage of gametogenesis in which alignment and synapsis of chromosomal pairs occur, allowing for the recombination of maternal and paternal genomes. Here we show that FK506 binding protein (Fkbp6) localizes to meiotic chromosome cores and regions of homologous chromosome synapsis. Targeted inactivation of Fkbp6 in mice results in aspermic males and the absence of normal pachytene spermatocytes. Moreover, we identified the deletion of Fkbp6 exon 8 as the causative mutation in spontaneously male sterile as/as mutant rats. Loss of Fkbp6 results in abnormal pairing and misalignments between homologous chromosomes, nonhomologous partner switches, and autosynapsis of X chromosome cores in meiotic spermatocytes. Fertility and meiosis are normal in Fkbp6 mutant females. Thus, Fkbp6 is a component of the synaptonemal complex essential for sex-specific fertility and for the fidelity of homologous chromosome pairing in meiosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882960/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882960/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crackower, Michael A -- Kolas, Nadine K -- Noguchi, Junko -- Sarao, Renu -- Kikuchi, Kazuhiro -- Kaneko, Hiroyuki -- Kobayashi, Eiji -- Kawai, Yasuhiro -- Kozieradzki, Ivona -- Landers, Rushin -- Mo, Rong -- Hui, Chi-Chung -- Nieves, Edward -- Cohen, Paula E -- Osborne, Lucy R -- Wada, Teiji -- Kunieda, Tetsuo -- Moens, Peter B -- Penninger, Josef M -- 38103/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2003 May 23;300(5623):1291-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA), c/o Dr. Bohrgasse 7, 1030, Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12764197" target="_blank"〉PubMed〈/a〉

    Spatiotemporal rescue of memory dysfunction in Drosophila (2003)

    Details
    Publication Date: 2003-12-06
    Description: We have developed a method for temporal and regional gene expression targeting (TARGET) in Drosophila and show the simultaneous spatial and temporal rescue of a memory defect. The transient expression of the rutabaga-encoded adenylyl cyclase in the mushroom bodies of the adult brain was necessary and sufficient to rescue the rutabaga memory deficit, which rules out a developmental brain defect in the etiology of this deficit and demonstrates an acute role for rutabaga in memory formation in these neurons. The TARGET system offers general utility in simultaneously addressing issues of when and where gene products are required.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGuire, Sean E -- Le, Phuong T -- Osborn, Alexander J -- Matsumoto, Kunihiro -- Davis, Ronald L -- GM63929/GM/NIGMS NIH HHS/ -- NS19904/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1765-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14657498" target="_blank"〉PubMed〈/a〉

    Trophoblast L-selectin-mediated adhesion at the maternal-fetal interface (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-18
    Description: Trophoblast adhesion to the uterine wall is the requisite first step of implantation and, subsequently, placentation. At the maternal-fetal interface, we investigated the expression of selectin adhesion systems that enable leukocyte capture from the bloodstream. On the maternal side, human uterine epithelial cells up-regulated selectin oligosaccharide-based ligands during the window of receptivity. On the fetal side, human trophoblasts expressed L-selectin. This ligand-receptor system was functional, because beads coated with the selectin ligand 6-sulfo sLe(x) bound to trophoblasts, and trophoblasts bound to ligand-expressing uterine luminal epithelium in tissue sections. These results suggest that trophoblast L-selectin mediates interactions with the uterus and that this adhesion mechanism may be critical to establishing human pregnancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Genbacev, Olga D -- Prakobphol, Akraporn -- Foulk, Russell A -- Krtolica, Ana R -- Ilic, Dusko -- Singer, Mark S -- Yang, Zhi-Qiang -- Kiessling, Laura L -- Rosen, Steven D -- Fisher, Susan J -- DE 07244/DE/NIDCR NIH HHS/ -- HL 64597/HL/NHLBI NIH HHS/ -- R37GM23547/GM/NIGMS NIH HHS/ -- U01 HD 42283/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2003 Jan 17;299(5605):405-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Stomatology, Anatomy, and Pharmaceutical Chemistry, University of California, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12532021" target="_blank"〉PubMed〈/a〉

    A protein interaction map of Drosophila melanogaster (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-08
    Description: Drosophila melanogaster is a proven model system for many aspects of human biology. Here we present a two-hybrid-based protein-interaction map of the fly proteome. A total of 10,623 predicted transcripts were isolated and screened against standard and normalized complementary DNA libraries to produce a draft map of 7048 proteins and 20,405 interactions. A computational method of rating two-hybrid interaction confidence was developed to refine this draft map to a higher confidence map of 4679 proteins and 4780 interactions. Statistical modeling of the network showed two levels of organization: a short-range organization, presumably corresponding to multiprotein complexes, and a more global organization, presumably corresponding to intercomplex connections. The network recapitulated known pathways, extended pathways, and uncovered previously unknown pathway components. This map serves as a starting point for a systems biology modeling of multicellular organisms, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giot, L -- Bader, J S -- Brouwer, C -- Chaudhuri, A -- Kuang, B -- Li, Y -- Hao, Y L -- Ooi, C E -- Godwin, B -- Vitols, E -- Vijayadamodar, G -- Pochart, P -- Machineni, H -- Welsh, M -- Kong, Y -- Zerhusen, B -- Malcolm, R -- Varrone, Z -- Collis, A -- Minto, M -- Burgess, S -- McDaniel, L -- Stimpson, E -- Spriggs, F -- Williams, J -- Neurath, K -- Ioime, N -- Agee, M -- Voss, E -- Furtak, K -- Renzulli, R -- Aanensen, N -- Carrolla, S -- Bickelhaupt, E -- Lazovatsky, Y -- DaSilva, A -- Zhong, J -- Stanyon, C A -- Finley, R L Jr -- White, K P -- Braverman, M -- Jarvie, T -- Gold, S -- Leach, M -- Knight, J -- Shimkets, R A -- McKenna, M P -- Chant, J -- Rothberg, J M -- HG01536/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1727-36.

    Redox regulation of germline and vulval development in Caenorhabditis elegans (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-06
    Description: In vitro studies have indicated that reactive oxygen species (ROS) and the oxidation of signaling molecules are important mediators of signal transduction. We have identified two pathways by which the altered redox chemistry of the clk-1 mutants of Caenorhabditis elegans acts in vivo on germline development. One pathway depends on the oxidation of an analog of vertebrate low density lipoprotein (LDL) and acts on the germline through the Ack-related tyrosine kinase (ARK-1) kinase and inositol trisphosphate (IP3) signaling. The other pathway is the oncogenic ras signaling pathway, whose action on germline as well as vulval development appears to be modulated by cytoplasmic ROS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, Yukimasa -- Branicky, Robyn -- Landaverde, Irene Oviedo -- Hekimi, Siegfried -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1779-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, McGill University, 1205 Avenue Docteur Penfield, Montreal, Quebec, Canada, H3A 1B1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14657502" target="_blank"〉PubMed〈/a〉

    Resurrecting the ancestral steroid receptor: ancient origin of estrogen signaling (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-23
    Description: Receptors for sex and adrenal steroid hormones are absent from fully sequenced invertebrate genomes and have not been recovered from other invertebrates. Here we report the isolation of an estrogen receptor ortholog from the mollusk Aplysia californica and the reconstruction, synthesis, and experimental characterization of functional domains of the ancestral protein from which all extant steroid receptors (SRs) evolved. Our findings indicate that SRs are extremely ancient and widespread, having diversified from a primordial gene before the origin of bilaterally symmetric animals, and that this ancient receptor had estrogen receptor-like functionality. This gene was lost in the lineage leading to arthropods and nematodes and became independent of hormone regulation in the Aplysia lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thornton, Joseph W -- Need, Eleanor -- Crews, David -- 41770/PHS HHS/ -- New York, N.Y. -- Science. 2003 Sep 19;301(5640):1714-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Ecology and Evolutionary Biology, University of Oregon, Eugene, OR 97403, USA. joet@uoregon.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14500980" target="_blank"〉PubMed〈/a〉

    Description: Gene enrichment strategies offer an alternative to sequencing large and repetitive genomes such as that of maize. We report the generation and analysis of nearly 100,000 undermethylated (or methylation filtration) maize sequences. Comparison with the rice genome reveals that methylation filtration results in a more comprehensive representation of maize genes than those that result from expressed sequence tags or transposon insertion sites sequences. About 7% of the repetitive DNA is unmethylated and thus selected in our libraries, but potentially active transposons and unmethylated organelle genomes can be identified. Reverse transcription polymerase chain reaction can be used to finish the maize transcriptome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palmer, Lance E -- Rabinowicz, Pablo D -- O'Shaughnessy, Andrew L -- Balija, Vivekanand S -- Nascimento, Lidia U -- Dike, Sujit -- de la Bastide, Melissa -- Martienssen, Robert A -- McCombie, W Richard -- 2 T32-CA09311-25/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2115-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, 1 Bungtown Road, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684820" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2003-03-29
    Description: Although it has been known for some time that olfactory receptors (ORs) reside in spermatozoa, the function of these ORs is unknown. Here, we identified, cloned, and functionally expressed a previously undescribed human testicular OR, hOR17-4. With the use of ratiofluorometric imaging, Ca2+ signals were induced by a small subset of applied chemical stimuli, establishing the molecular receptive fields for the recombinantly expressed receptor in human embryonic kidney (HEK) 293 cells and the native receptor in human spermatozoa. Bourgeonal was a powerful agonist for both recombinant and native receptor types, as well as a strong chemoattractant in subsequent behavioral bioassays. In contrast, undecanal was a potent OR antagonist to bourgeonal and related compounds. Taken together, these results indicate that hOR17-4 functions in human sperm chemotaxis and may be a critical component of the fertilization process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spehr, Marc -- Gisselmann, Gunter -- Poplawski, Alexandra -- Riffell, Jeffrey A -- Wetzel, Christian H -- Zimmer, Richard K -- Hatt, Hanns -- New York, N.Y. -- Science. 2003 Mar 28;299(5615):2054-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, Ruhr University Bochum, 150 University Street, D-44780 Bochum, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12663925" target="_blank"〉PubMed〈/a〉

    Description: Bixin, also known as annatto, is a seed-specific pigment widely used in foods and cosmetics since pre-Columbian times. We show that three genes from Bixa orellana, native to tropical America, govern bixin biosynthesis. These genes code for lycopene cleavage dioxygenase, bixin aldehyde dehydrogenase, and norbixin carboxyl methyltransferase, which catalyze the sequential conversion of lycopene into bixin. Introduction of these three genes in Escherichia coli engineered to produce lycopene induced bixin synthesis, thus expanding the supply of this economically important plant product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bouvier, Florence -- Dogbo, Odette -- Camara, Bilal -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2089-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Biologie Moleculaire des Plantes, CNRS, Universite Louis Pasteur, 67084 Strasbourg, Cedex, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12829782" target="_blank"〉PubMed〈/a〉

    Loss of an MDR transporter in compact stalks of maize br2 and sorghum dw3 mutants (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Agriculturally advantageous reduction in plant height is usually achieved by blocking the action or production of gibberellins. Here, we describe a different dwarfing mechanism found in maize brachytic2 (br2) mutants characterized by compact lower stalk internodes. The height reduction in these plants results from the loss of a P-glycoprotein that modulates polar auxin transport in the maize stalk. The sorghum ortholog of br2 is dwarf3 (dw3), an unstable mutant of long-standing commercial interest and concern. A direct duplication within the dw3 gene is responsible for its mutant nature and also for its instability, because it facilitates unequal crossing-over at the locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Multani, Dilbag S -- Briggs, Steven P -- Chamberlin, Mark A -- Blakeslee, Joshua J -- Murphy, Angus S -- Johal, Gurmukh S -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):81-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pioneer Hi-Bred International, 7250 Northwest 62nd Avenue, Johnston, IA 50131, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526073" target="_blank"〉PubMed〈/a〉

    Description: The recently released human genome sequences provide us with reference data to conduct comparative genomic research on primates, which will be important to understand what genetic information makes us human. Here we present a first-generation human-chimpanzee comparative genome map and its initial analysis. The map was constructed through paired alignment of 77,461 chimpanzee bacterial artificial chromosome end sequences with publicly available human genome sequences. We detected candidate positions, including two clusters on human chromosome 21 that suggest large, nonrandom regions of difference between the two genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujiyama, Asao -- Watanabe, Hidemi -- Toyoda, Atsushi -- Taylor, Todd D -- Itoh, Takehiko -- Tsai, Shih-Feng -- Park, Hong-Seog -- Yaspo, Marie-Laure -- Lehrach, Hans -- Chen, Zhu -- Fu, Gang -- Saitou, Naruya -- Osoegawa, Kazutoyo -- de Jong, Pieter J -- Suto, Yumiko -- Hattori, Masahira -- Sakaki, Yoshiyuki -- New York, N.Y. -- Science. 2002 Jan 4;295(5552):131-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Genomic Sciences Center, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. afujiyam@gsc.riken.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11778049" target="_blank"〉PubMed〈/a〉

    Stromal effects on mammary gland development and breast cancer (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-11
    Description: Breast cancer manifests itself in the mammary epithelium, yet there is a growing recognition that mammary stromal cells also play an important role in tumorigenesis. During its developmental cycle, the mammary gland displays many of the properties associated with breast cancer, and many of the stromal factors necessary for mammary development also promote or protect against breast cancer. Here we review our present knowledge of the specific factors and cell types that contribute to epithelial-stromal crosstalk during mammary development. To find cures for diseases like breast cancer that rely on epithelial-stromal crosstalk, we must understand how these different cell types communicate with each other.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2788989/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2788989/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wiseman, Bryony S -- Werb, Zena -- CA57621/CA/NCI NIH HHS/ -- R01 CA057621/CA/NCI NIH HHS/ -- R01 CA057621-07/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2002 May 10;296(5570):1046-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy, University of California, 513 Parnassus Avenue, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004111" target="_blank"〉PubMed〈/a〉

    A tomato cysteine protease required for Cf-2-dependent disease resistance and suppression of autonecrosis (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-04-27
    Description: Little is known of how plant disease resistance (R) proteins recognize pathogens and activate plant defenses. Rcr3 is specifically required for the function of Cf-2, a Lycopersicon pimpinellifolium gene bred into cultivated tomato (Lycopersicon esculentum) for resistance to Cladosporium fulvum. Rcr3 encodes a secreted papain-like cysteine endoprotease. Genetic analysis shows Rcr3 is allelic to the L. pimpinellifolium Ne gene, which suppresses the Cf-2-dependent autonecrosis conditioned by its L. esculentum allele, ne (necrosis). Rcr3 alleles from these two species encode proteins that differ by only seven amino acids. Possible roles of Rcr3 in Cf-2-dependent defense and autonecrosis are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kruger, Julia -- Thomas, Colwyn M -- Golstein, Catherine -- Dixon, Mark S -- Smoker, Matthew -- Tang, Saijun -- Mulder, Lonneke -- Jones, Jonathan D G -- New York, N.Y. -- Science. 2002 Apr 26;296(5568):744-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Sainsbury Laboratory, John Innes Centre, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11976458" target="_blank"〉PubMed〈/a〉

    Female germ cell aneuploidy and embryo death in mice lacking the meiosis-specific protein SCP3 (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-11
    Description: Aneuploidy (trisomy or monosomy) is the leading genetic cause of pregnancy loss in humans and results from errors in meiotic chromosome segregation. Here, we show that the absence of synaptonemal complex protein 3 (SCP3) promotes aneuploidy in murine oocytes by inducing defective meiotic chromosome segregation. The abnormal oocyte karyotype is inherited by embryos, which die in utero at an early stage of development. In addition, embryo death in SCP3-deficient females increases with advancing maternal age. We found that SCP3 is required for chiasmata formation and for the structural integrity of meiotic chromosomes, suggesting that altered chromosomal structure triggers nondisjunction. SCP3 is thus linked to inherited aneuploidy in female germ cells and provides a model system for studying age-dependent degeneration in oocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yuan, Li -- Liu, Jian-Guo -- Hoja, Mary-Rose -- Wilbertz, Johannes -- Nordqvist, Katarina -- Hoog, Christer -- New York, N.Y. -- Science. 2002 May 10;296(5570):1115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genomics and Bioinformatics and Department of Cell and Molecular Biology, Karolinska Institutet, SE-171 77 Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004129" target="_blank"〉PubMed〈/a〉

    A heat-sensitive TRP channel expressed in keratinocytes (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-23
    Description: Mechanical and thermal cues stimulate a specialized group of sensory neurons that terminate in the skin. Three members of the transient receptor potential (TRP) family of channels are expressed in subsets of these neurons and are activated at distinct physiological temperatures. Here, we describe the cloning and characterization of a novel thermosensitive TRP channel. TRPV3 has a unique threshold: It is activated at innocuous (warm) temperatures and shows an increased response at noxious temperatures. TRPV3 is specifically expressed in keratinocytes; hence, skin cells are capable of detecting heat via molecules similar to those in heat-sensing neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peier, Andrea M -- Reeve, Alison J -- Andersson, David A -- Moqrich, Aziz -- Earley, Taryn J -- Hergarden, Anne C -- Story, Gina M -- Colley, Sian -- Hogenesch, John B -- McIntyre, Peter -- Bevan, Stuart -- Patapoutian, Ardem -- New York, N.Y. -- Science. 2002 Jun 14;296(5575):2046-9.

    Publication Date: 2002-05-04
    Description: A liquid crystal system was used for the fabrication of a highly ordered composite material from genetically engineered M13 bacteriophage and zinc sulfide (ZnS) nanocrystals. The bacteriophage, which formed the basis of the self-ordering system, were selected to have a specific recognition moiety for ZnS crystal surfaces. The bacteriophage were coupled with ZnS solution precursors and spontaneously evolved a self-supporting hybrid film material that was ordered at the nanoscale and at the micrometer scale into approximately 72-micrometer domains, which were continuous over a centimeter length scale. In addition, suspensions were prepared in which the lyotropic liquid crystalline phase behavior of the hybrid material was controlled by solvent concentration and by the use of a magnetic field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Seung-Wuk -- Mao, Chuanbin -- Flynn, Christine E -- Belcher, Angela M -- New York, N.Y. -- Science. 2002 May 3;296(5569):892-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, Center for Nano- and Molecular Science and Technology, Texas Materials Institute, Institute for Cellular and Molecular Biology, University of Texas at Austin, Austin, TX 78712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11988570" target="_blank"〉PubMed〈/a〉

    Metabolic enzymes of mycobacteria linked to antioxidant defense by a thioredoxin-like protein (2002)

    Details
    Publication Date: 2002-01-19
    Description: Mycobacterium tuberculosis (Mtb) mounts a stubborn defense against oxidative and nitrosative components of the immune response. Dihydrolipoamide dehydrogenase (Lpd) and dihydrolipoamide succinyltransferase (SucB) are components of alpha-ketoacid dehydrogenase complexes that are central to intermediary metabolism. We find that Lpd and SucB support Mtb's antioxidant defense. The peroxiredoxin alkyl hydroperoxide reductase (AhpC) is linked to Lpd and SucB by an adaptor protein, AhpD. The 2.0 angstrom AhpD crystal structure reveals a thioredoxin-like active site that is responsive to lipoamide. We propose that Lpd, SucB (the only lipoyl protein detected in Mtb), AhpD, and AhpC together constitute a nicotinamide adenine dinucleotide (reduced)-dependent peroxidase and peroxynitrite reductase. AhpD thus represents a class of thioredoxin-like molecules that enables an antioxidant defense.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bryk, R -- Lima, C D -- Erdjument-Bromage, H -- Tempst, P -- Nathan, C -- HL61241/HL/NHLBI NIH HHS/ -- P30 CA08748/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1073-7.

    Spider silk fibers spun from soluble recombinant silk produced in mammalian cells (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-01-19
    Description: Spider silks are protein-based "biopolymer" filaments or threads secreted by specialized epithelial cells as concentrated soluble precursors of highly repetitive primary sequences. Spider dragline silk is a flexible, lightweight fiber of extraordinary strength and toughness comparable to that of synthetic high-performance fibers. We sought to "biomimic" the process of spider silk production by expressing in mammalian cells the dragline silk genes (ADF-3/MaSpII and MaSpI) of two spider species. We produced soluble recombinant (rc)-dragline silk proteins with molecular masses of 60 to 140 kilodaltons. We demonstrated the wet spinning of silk monofilaments spun from a concentrated aqueous solution of soluble rc-spider silk protein (ADF-3; 60 kilodaltons) under modest shear and coagulation conditions. The spun fibers were water insoluble with a fine diameter (10 to 40 micrometers) and exhibited toughness and modulus values comparable to those of native dragline silks but with lower tenacity. Dope solutions with rc-silk protein concentrations 〉20% and postspinning draw were necessary to achieve improved mechanical properties of the spun fibers. Fiber properties correlated with finer fiber diameter and increased birefringence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lazaris, Anthoula -- Arcidiacono, Steven -- Huang, Yue -- Zhou, Jiang-Feng -- Duguay, Francois -- Chretien, Nathalie -- Welsh, Elizabeth A -- Soares, Jason W -- Karatzas, Costas N -- New York, N.Y. -- Science. 2002 Jan 18;295(5554):472-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nexia Biotechnologies, Vaudreuil-Dorion, Quebec J7V 8P5, Canada. alazaris@nexiabiotech.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11799236" target="_blank"〉PubMed〈/a〉

    The calicheamicin gene cluster and its iterative type I enediyne PKS (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-08-17
    Description: The enediynes exemplify nature's ingenuity. We have cloned and characterized the biosynthetic locus coding for perhaps the most notorious member of the nonchromoprotein enediyne family, calicheamicin. This gene cluster contains an unusual polyketide synthase (PKS) that is demonstrated to be essential for enediyne biosynthesis. Comparison of the calicheamicin locus with the locus encoding the chromoprotein enediyne C-1027 reveals that the enediyne PKS is highly conserved among these distinct enediyne families. Contrary to previous hypotheses, this suggests that the chromoprotein and nonchromoprotein enediynes are generated by similar biosynthetic pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahlert, Joachim -- Shepard, Erica -- Lomovskaya, Natalia -- Zazopoulos, Emmanuel -- Staffa, Alfredo -- Bachmann, Brian O -- Huang, Kexue -- Fonstein, Leonid -- Czisny, Anne -- Whitwam, Ross E -- Farnet, Chris M -- Thorson, Jon S -- CA08748/CA/NCI NIH HHS/ -- CA84374/CA/NCI NIH HHS/ -- GM58196/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1173-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Biosynthetic Chemistry, Pharmaceutical Sciences Division, School of Pharmacy, University of Wisconsin-Madison, 777 Highland Avenue, Madison, WI 53705, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12183629" target="_blank"〉PubMed〈/a〉

    Biosynthesis of the enediyne antitumor antibiotic C-1027 (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-08-17
    Description: C-1027 is a potent antitumor agent with a previously undescribed molecular architecture and mode of action. Cloning and characterization of the 85-kilobase C-1027 biosynthesis gene cluster from Streptomyces globisporus revealed (i) an iterative type I polyketide synthase that is distinct from any bacterial polyketide synthases known to date, (ii) a general polyketide pathway for the biosynthesis of both the 9- and 10-membered enediyne antibiotics, and (iii) a convergent biosynthetic strategy for the C-1027 chromophore from four building blocks. Manipulation of genes governing C-1027 biosynthesis allowed us to produce an enediyne compound in a predicted manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Wen -- Christenson, Steven D -- Standage, Scott -- Shen, Ben -- AI51689/AI/NIAID NIH HHS/ -- CA78747/CA/NCI NIH HHS/ -- T32 GM07377/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1170-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Pharmaceutical Sciences, University of Wisconsin, Madison, WI 53705, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12183628" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2002-03-23
    Description: Full-length complementary DNAs (cDNAs) are essential for the correct annotation of genomic sequences and for the functional analysis of genes and their products. We isolated 155,144 RIKEN Arabidopsis full-length (RAFL) cDNA clones. The 3'-end expressed sequence tags (ESTs) of 155,144 RAFL cDNAs were clustered into 14,668 nonredundant cDNA groups, about 60% of predicted genes. We also obtained 5' ESTs from 14,034 nonredundant cDNA groups and constructed a promoter database. The sequence database of the RAFL cDNAs is useful for promoter analysis and correct annotation of predicted transcription units and gene products. Furthermore, the full-length cDNAs are useful resources for analyses of the expression profiles, functions, and structures of plant proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seki, Motoaki -- Narusaka, Mari -- Kamiya, Asako -- Ishida, Junko -- Satou, Masakazu -- Sakurai, Tetsuya -- Nakajima, Maiko -- Enju, Akiko -- Akiyama, Kenji -- Oono, Youko -- Muramatsu, Masami -- Hayashizaki, Yoshihide -- Kawai, Jun -- Carninci, Piero -- Itoh, Masayoshi -- Ishii, Yoshiyuki -- Arakawa, Takahiro -- Shibata, Kazuhiro -- Shinagawa, Akira -- Shinozaki, Kazuo -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):141-5.

    Multiple roles of Arabidopsis VRN1 in vernalization and flowering time control (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-07-13
    Description: Arabidopsis VRN genes mediate vernalization, the process by which a long period of cold induces a mitotically stable state that leads to accelerated flowering during later development. VRN1 encodes a protein that binds DNA in vitro in a non-sequence-specific manner and functions in stable repression of the major target of the vernalization pathway, the floral repressor FLC. Overexpression of VRN1 reveals a vernalization-independent function for VRN1, mediated predominantly through the floral pathway integrator FT, and demonstrates that VRN1 requires vernalization-specific factors to target FLC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, Yaron Y -- Mesnage, Stephane -- Mylne, Joshua S -- Gendall, Anthony R -- Dean, Caroline -- New York, N.Y. -- Science. 2002 Jul 12;297(5579):243-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, John Innes Centre, Colney Lane, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12114624" target="_blank"〉PubMed〈/a〉

    A MADS-box gene necessary for fruit ripening at the tomato ripening-inhibitor (rin) locus (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-04-16
    Description: Tomato plants harboring the ripening-inhibitor (rin) mutation yield fruits that fail to ripen. Additionally, rin plants display enlarged sepals and loss of inflorescence determinacy. Positional cloning of the rin locus revealed two tandem MADS-box genes (LeMADS-RIN and LeMADS-MC), whose expression patterns suggested roles in fruit ripening and sepal development, respectively. The rin mutation alters expression of both genes. Gene repression and mutant complementation demonstrate that LeMADS-RIN regulates ripening, whereas LeMADS-MC affects sepal development and inflorescence determinacy. LeMADS-RIN demonstrates an agriculturally important function of plant MADS-box genes and provides molecular insight into nonhormonal (developmental) regulation of ripening.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vrebalov, Julia -- Ruezinsky, Diane -- Padmanabhan, Veeraragavan -- White, Ruth -- Medrano, Diana -- Drake, Rachel -- Schuch, Wolfgang -- Giovannoni, Jim -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):343-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) Plant, Soil and Nutrition Lab and Boyce Thompson Institute for Plant Research, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11951045" target="_blank"〉PubMed〈/a〉
