    Beschreibung: Primate-specific segmental duplications are considered important in human disease and evolution. The inability to distinguish between allelic and duplication sequence overlap has hampered their characterization as well as assembly and annotation of our genome. We developed a method whereby each public sequence is analyzed at the clone level for overrepresentation within a whole-genome shotgun sequence. This test has the ability to detect duplications larger than 15 kilobases irrespective of copy number, location, or high sequence similarity. We mapped 169 large regions flanked by highly similar duplications. Twenty-four of these hot spots of genomic instability have been associated with genetic disease. Our analysis indicates a highly nonrandom chromosomal and genic distribution of recent segmental duplications, with a likely role in expanding protein diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bailey, Jeffrey A -- Gu, Zhiping -- Clark, Royden A -- Reinert, Knut -- Samonte, Rhea V -- Schwartz, Stuart -- Adams, Mark D -- Myers, Eugene W -- Li, Peter W -- Eichler, Evan E -- CA094816/CA/NCI NIH HHS/ -- GM58815/GM/NIGMS NIH HHS/ -- HG002318/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 9;297(5583):1003-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Center for Computational Genomics, and Center for Human Genetics, Case Western Reserve University School of Medicine and University Hospitals of Cleveland, Cleveland, OH 44106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12169732" target="_blank"〉PubMed〈/a〉

    Beschreibung: Analysis of tetrapod footprints and skeletal material from more than 70 localities in eastern North America shows that large theropod dinosaurs appeared less than 10,000 years after the Triassic-Jurassic boundary and less than 30,000 years after the last Triassic taxa, synchronous with a terrestrial mass extinction. This extraordinary turnover is associated with an iridium anomaly (up to 285 parts per trillion, with an average maximum of 141 parts per trillion) and a fern spore spike, suggesting that a bolide impact was the cause. Eastern North American dinosaurian diversity reached a stable maximum less than 100,000 years after the boundary, marking the establishment of dinosaur-dominated communities that prevailed for the next 135 million years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, P E -- Kent, D V -- Sues, H-D -- Koeberl, C -- Huber, H -- Montanari, A -- Rainforth, E C -- Fowell, S J -- Szajna, M J -- Hartline, B W -- New York, N.Y. -- Science. 2002 May 17;296(5571):1305-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12016313" target="_blank"〉PubMed〈/a〉

    Beschreibung: KNOTTEDI-like homeobox (KNOXI) genes regulate development of the leaf from the shoot apical meristem (SAM) and may regulate leaf form. We examined KNOXI expression in SAMs of various vascular plants and found that KNOXI expression correlated with complex leaf primordia. However, complex primordia may mature into simple leaves. Therefore, not all simple leaves develop similarly, and final leaf morphology may not be an adequate predictor of homology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bharathan, Geeta -- Goliber, Thomas E -- Moore, Christopher -- Kessler, Sharon -- Pham, Thinh -- Sinha, Neelima R -- New York, N.Y. -- Science. 2002 Jun 7;296(5574):1858-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, State University of New York, Stony Brook, NY 11794-5245, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12052958" target="_blank"〉PubMed〈/a〉

    Beschreibung: Social insects show multiple levels of self identity. Most individuals are sterile workers who selflessly labor for their colony, which is often viewed as a superorganism. The superorganism protects itself with colony recognition systems based on learned odors, typically cuticular hydrocarbons. Transfer of these odors within the colony obscures separate clan identities. Residual individual interests do appear to cause conflicts within colonies over sex ratio, male production, caste, and reproductive dominance. However, genomic imprinting theory predicts that the individual's maternal and paternal genes will evolve separate infraorganismal identities, perhaps leaving virtually no coherent individual identity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Queller, David C -- Strassmann, Joan E -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):311-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Mail Stop-170, Rice University, Post Office Box 1892, Houston, TX 77251-1892, USA.

    Beschreibung: Thermophilic microbial inhabitants of active seafloor and continental hot springs populate the deepest branches of the universal phylogenetic tree, making hydrothermal ecosystems the most ancient continuously inhabited ecosystems on Earth. Geochemical consequences of hot water-rock interactions render these environments habitable and supply a diverse array of energy sources. Clues to the strategies for how life thrives in these dynamic ecosystems are beginning to be elucidated through a confluence of biogeochemistry, microbiology, ecology, molecular biology, and genomics. These efforts have the potential to reveal how ecosystems originate, the extent of the subsurface biosphere, and the driving forces of evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reysenbach, Anna-Louise -- Shock, Everett -- New York, N.Y. -- Science. 2002 May 10;296(5570):1077-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Portland State University, Portland, OR 97201, USA. reysenbacha@pdx.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004120" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although humans and their closest evolutionary relatives, the chimpanzees, are 98.7% identical in their genomic DNA sequences, they differ in many morphological, behavioral, and cognitive aspects. The underlying genetic basis of many of these differences may be altered gene expression. We have compared the transcriptome in blood leukocytes, liver, and brain of humans, chimpanzees, orangutans, and macaques using microarrays, as well as protein expression patterns of humans and chimpanzees using two-dimensional gel electrophoresis. We also studied three mouse species that are approximately as related to each other as are humans, chimpanzees, and orangutans. We identified species-specific gene expression patterns indicating that changes in protein and gene expression have been particularly pronounced in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Enard, Wolfgang -- Khaitovich, Philipp -- Klose, Joachim -- Zollner, Sebastian -- Heissig, Florian -- Giavalisco, Patrick -- Nieselt-Struwe, Kay -- Muchmore, Elaine -- Varki, Ajit -- Ravid, Rivka -- Doxiadis, Gaby M -- Bontrop, Ronald E -- Paabo, Svante -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):340-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute for Evolutionary Anthropology, Inselstrasse 22, D-04103 Leipzig, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11951044" target="_blank"〉PubMed〈/a〉

    Beschreibung: Numerous saturated and aromatic hydrocarbons, but not polar compounds, originating from plants and microorganisms (biomarkers) have been reported in sediments, coals, and petroleum. Here we describe natural product terpenoids found in two fossil conifers, Taxodium balticum (Eocene) and Glyptostrobus oregonensis (Miocene). A similar terpenoid pattern is also observed in extant Taxodium distichum. The preservation of characteristic terpenoids (unaltered natural products) in the fossil conifers supports their systematic assignment to the Cypress family (Cupressaceae sensu lato). The results also show that fossil conifers can contain polar terpenoids, which are valuable markers for (paleo)chemosystematics and phylogeny.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Otto, Angelika -- White, James D -- Simoneit, Bernd R T -- New York, N.Y. -- Science. 2002 Aug 30;297(5586):1543-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental and Petroleum Geochemistry Group, College of Oceanic and Atmospheric Sciences, Oregon State University, Corvallis, OR 97331, USA. a.otto@kristall.uni-frankfurt.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12202827" target="_blank"〉PubMed〈/a〉

    Beschreibung: Comparison of two fully sequenced genomes of Buchnera aphidicola, the obligate endosymbionts of aphids, reveals the most extreme genome stability to date: no chromosome rearrangements or gene acquisitions have occurred in the past 50 to 70 million years, despite substantial sequence evolution and the inactivation and loss of individual genes. In contrast, the genomes of their closest free-living relatives, Escherichia coli and Salmonella spp., are more than 2000-fold more labile in content and gene order. The genomic stasis of B. aphidicola, likely attributable to the loss of phages, repeated sequences, and recA, indicates that B. aphidicola is no longer a source of ecological innovation for its hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tamas, Ivica -- Klasson, Lisa -- Canback, Bjorn -- Naslund, A Kristina -- Eriksson, Ann-Sofie -- Wernegreen, Jennifer J -- Sandstrom, Jonas P -- Moran, Nancy A -- Andersson, Siv G E -- New York, N.Y. -- Science. 2002 Jun 28;296(5577):2376-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Evolution, Evolutionary Biology Center, University of Uppsala, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12089438" target="_blank"〉PubMed〈/a〉

    Beschreibung: Advanced technologies and biology have extremely different physical implementations, but they are far more alike in systems-level organization than is widely appreciated. Convergent evolution in both domains produces modular architectures that are composed of elaborate hierarchies of protocols and layers of feedback regulation, are driven by demand for robustness to uncertain environments, and use often imprecise components. This complexity may be largely hidden in idealized laboratory settings and in normal operation, becoming conspicuous only when contributing to rare cascading failures. These puzzling and paradoxical features are neither accidental nor artificial, but derive from a deep and necessary interplay between complexity and robustness, modularity, feedback, and fragility. This review describes insights from engineering theory and practice that can shed some light on biological complexity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Csete, Marie E -- Doyle, John C -- New York, N.Y. -- Science. 2002 Mar 1;295(5560):1664-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anesthesiology, University of Michigan Medical School, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11872830" target="_blank"〉PubMed〈/a〉

    Beschreibung: There are probably millions of species in the microorganismal domains Bacteria and Archaea (the prokaryotes), and we are only just beginning to work out the basic principles governing their distribution and abundance in natural environments. One characteristic that has become clear is that prokaryote diversity in aquatic environments is orders of magnitude less than in sediments and soils. Hypotheses and models explaining such differences are under development and are beginning to offer promising insights into the mechanisms governing prokaryote diversity and ecosystem function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Torsvik, Vigdis -- Ovreas, Lise -- Thingstad, Tron Frede -- New York, N.Y. -- Science. 2002 May 10;296(5570):1064-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Bergen, Jahnebakken 5, N-5020 Bergen, Norway. vigdis.torsvik@im.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004116" target="_blank"〉PubMed〈/a〉

    Beschreibung: Harvesting light to produce energy and oxygen (photosynthesis) is the signature of all land plants. This ability was co-opted from a precocious and ancient form of life known as cyanobacteria. Today these bacteria, as well as microscopic algae, supply oxygen to the atmosphere and churn out fixed nitrogen in Earth's vast oceans. Microorganisms may also have played a major role in atmosphere evolution before the rise of oxygen. Under the more dim light of a young sun cooler than today's, certain groups of anaerobic bacteria may have been pumping out large amounts of methane, thereby keeping the early climate warm and inviting. The evolution of Earth's atmosphere is linked tightly to the evolution of its biota.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasting, James F -- Siefert, Janet L -- New York, N.Y. -- Science. 2002 May 10;296(5570):1066-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, 443 Deike, The Pennsylvania State University, University Park, PA 16802, USA. kasting@essc.psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004117" target="_blank"〉PubMed〈/a〉

    Beschreibung: The pha-4 locus encodes a forkhead box A (FoxA/HNF3) transcription factor homolog that specifies organ identity for Caenorhabditis elegans pharyngeal cells. We used microarrays to identify pharyngeal genes and analyzed those genes to determine which were direct PHA-4 targets. Our data suggest that PHA-4 directly activates most or all pharyngeal genes. Furthermore, the relative affinity of PHA-4 for different TRTTKRY (R = A/G, K = T/G, Y = T/C) elements modulates the onset of gene expression, providing a mechanism to activate pharyngeal genes at different developmental stages. We suggest that direct transcriptional regulation of entire gene networks may be a common feature of organ identity genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gaudet, J -- Mango, S E -- CCSG 2P30CA42014/CC/ODCDC CDC HHS/ -- R01 GM056264/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Feb 1;295(5556):821-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Huntsman Cancer Institute, University of Utah, 2000 Circle of Hope, Salt Lake City, UT 84112, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11823633" target="_blank"〉PubMed〈/a〉

    Beschreibung: Type I ubiquitin-like proteins constitute a family of protein modifiers. Here we report the identification of a posttranslational protein modifier from Saccharomyces cerevisiae, Hub1. Overexpression of Hub1 resulted in enhanced conjugate formation when its carboxyl-terminal residue was deleted, suggesting that mature Hub1 may be produced by proteolytic processing. In vivo targets of Hub1 conjugation included cell polarity factors Sph1 and Hbt1. In the hub1Delta mutant, the subcellular localization of both Hbt1 and Sph1 was disrupted, and cell polarization during the formation of mating projections was defective. Consistent with these polarization defects, the hub1Delta mutant was deficient in mating.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dittmar, Gunnar A G -- Wilkinson, Caroline R M -- Jedrzejewski, Paul T -- Finley, Daniel -- GM58223/GM/NIGMS NIH HHS/ -- GM62663/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 29;295(5564):2442-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11923536" target="_blank"〉PubMed〈/a〉

    Beschreibung: The success of vertebrates was due in part to the acquisition and modification of jaws. Jaws are principally derived from the branchial arches, embryonic structures that exhibit proximodistal polarity. To investigate the mechanisms that specify the identity of skeletal elements within the arches, we examined mice lacking expression of Dlx5 and Dlx6, linked homeobox genes expressed distally but not proximally within the arches. Dlx5/6-/- mutants exhibit a homeotic transformation of lower jaws to upper jaws. We suggest that nested Dlx expression in the arches patterns their proximodistal axes. Evolutionary acquisition and subsequent refinement of jaws may have been dependent on modification of Dlx expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Depew, Michael J -- Lufkin, Thomas -- Rubenstein, John L R -- K02MH01046-01/MH/NIMH NIH HHS/ -- T32DE07204/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2002 Oct 11;298(5592):381-5.

    Beschreibung: Taxonomy and systematics underpin our ability to conserve and benefit from biodiversity in sustainable ways as envisaged under the Convention on Biological Diversity (CBD). Despite progress in phylogenetics towards reconstructing the "Tree of Life" and in biodiversity informatics, the fundamental documentation of species necessary to complete the inventory of life has lagged behind. It is argued that this reflects a lack of appreciation of the role played by species-level taxonomic information in underpinning conservation and sustainable use and under investment in the relevant institutions at the expense of supporting the centralised financial mechanism of the CBD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blackmore, Stephen -- New York, N.Y. -- Science. 2002 Oct 11;298(5592):365.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Royal Botanic Garden Edinburgh, Inverleith Row, Edinburgh, EH3 5LR, UK. s.blackmore@rbge.org.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12376687" target="_blank"〉PubMed〈/a〉

    Beschreibung: Comparison of the genomes and proteomes of the two diptera Anopheles gambiae and Drosophila melanogaster, which diverged about 250 million years ago, reveals considerable similarities. However, numerous differences are also observed; some of these must reflect the selection and subsequent adaptation associated with different ecologies and life strategies. Almost half of the genes in both genomes are interpreted as orthologs and show an average sequence identity of about 56%, which is slightly lower than that observed between the orthologs of the pufferfish and human (diverged about 450 million years ago). This indicates that these two insects diverged considerably faster than vertebrates. Aligned sequences reveal that orthologous genes have retained only half of their intron/exon structure, indicating that intron gains or losses have occurred at a rate of about one per gene per 125 million years. Chromosomal arms exhibit significant remnants of homology between the two species, although only 34% of the genes colocalize in small "microsyntenic" clusters, and major interarm transfers as well as intra-arm shuffling of gene order are detected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zdobnov, Evgeny M -- von Mering, Christian -- Letunic, Ivica -- Torrents, David -- Suyama, Mikita -- Copley, Richard R -- Christophides, George K -- Thomasova, Dana -- Holt, Robert A -- Subramanian, G Mani -- Mueller, Hans-Michael -- Dimopoulos, George -- Law, John H -- Wells, Michael A -- Birney, Ewan -- Charlab, Rosane -- Halpern, Aaron L -- Kokoza, Elena -- Kraft, Cheryl L -- Lai, Zhongwu -- Lewis, Suzanna -- Louis, Christos -- Barillas-Mury, Carolina -- Nusskern, Deborah -- Rubin, Gerald M -- Salzberg, Steven L -- Sutton, Granger G -- Topalis, Pantelis -- Wides, Ron -- Wincker, Patrick -- Yandell, Mark -- Collins, Frank H -- Ribeiro, Jose -- Gelbart, William M -- Kafatos, Fotis C -- Bork, Peer -- New York, N.Y. -- Science. 2002 Oct 4;298(5591):149-59.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12364792" target="_blank"〉PubMed〈/a〉

    Beschreibung: Sexual selection in mammals has resulted in the evolution of sexual size dimorphism (SSD), with males usually being the larger sex. Comparative analyses indicate that the evolution of SSD is associated with the evolution of male-biased mortality, suggesting a possible causal link between the two. Here, we use a comparative approach to investigate the possible role of parasites in generating this relation. We show that there is a robust association between male-biased parasitism and the degree of sexual selection, as measured by mating system (monogamous or polygynous) and by the degree of SSD. There is also a positive correlation, across taxa, between male-biased mortality and male-biased parasitism. These results are consistent with the hypothesis that parasites contribute to the observed association between SSD and male-biased mortality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, Sarah L -- Wilson, Kenneth -- New York, N.Y. -- Science. 2002 Sep 20;297(5589):2015-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biological Sciences, University of Stirling, Stirling, FK9 4LA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12242433" target="_blank"〉PubMed〈/a〉

    Beschreibung: The compact genome of Fugu rubripes has been sequenced to over 95% coverage, and more than 80% of the assembly is in multigene-sized scaffolds. In this 365-megabase vertebrate genome, repetitive DNA accounts for less than one-sixth of the sequence, and gene loci occupy about one-third of the genome. As with the human genome, gene loci are not evenly distributed, but are clustered into sparse and dense regions. Some "giant" genes were observed that had average coding sequence sizes but were spread over genomic lengths significantly larger than those of their human orthologs. Although three-quarters of predicted human proteins have a strong match to Fugu, approximately a quarter of the human proteins had highly diverged from or had no pufferfish homologs, highlighting the extent of protein evolution in the 450 million years since teleosts and mammals diverged. Conserved linkages between Fugu and human genes indicate the preservation of chromosomal segments from the common vertebrate ancestor, but with considerable scrambling of gene order.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aparicio, Samuel -- Chapman, Jarrod -- Stupka, Elia -- Putnam, Nik -- Chia, Jer-Ming -- Dehal, Paramvir -- Christoffels, Alan -- Rash, Sam -- Hoon, Shawn -- Smit, Arian -- Gelpke, Maarten D Sollewijn -- Roach, Jared -- Oh, Tania -- Ho, Isaac Y -- Wong, Marie -- Detter, Chris -- Verhoef, Frans -- Predki, Paul -- Tay, Alice -- Lucas, Susan -- Richardson, Paul -- Smith, Sarah F -- Clark, Melody S -- Edwards, Yvonne J K -- Doggett, Norman -- Zharkikh, Andrey -- Tavtigian, Sean V -- Pruss, Dmitry -- Barnstead, Mary -- Evans, Cheryl -- Baden, Holly -- Powell, Justin -- Glusman, Gustavo -- Rowen, Lee -- Hood, Leroy -- Tan, Y H -- Elgar, Greg -- Hawkins, Trevor -- Venkatesh, Byrappa -- Rokhsar, Daniel -- Brenner, Sydney -- New York, N.Y. -- Science. 2002 Aug 23;297(5585):1301-10.

    Beschreibung: Proliferation of legume nodule primordia is controlled by shoot-root signaling known as autoregulation of nodulation (AON). Mutants defective in AON show supernodulation and increased numbers of lateral roots. Here, we demonstrate that AON in soybean is controlled by the receptor-like protein kinase GmNARK (Glycine max nodule autoregulation receptor kinase), similar to Arabidopsis CLAVATA1 (CLV1). Whereas CLV1 functions in a protein complex controlling stem cell proliferation by short-distance signaling in shoot apices, GmNARK expression in the leaf has a major role in long-distance communication with nodule and lateral root primordia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Searle, Iain R -- Men, Artem E -- Laniya, Titeki S -- Buzas, Diana M -- Iturbe-Ormaetxe, Inaki -- Carroll, Bernard J -- Gresshoff, Peter M -- New York, N.Y. -- Science. 2003 Jan 3;299(5603):109-12.

    Beschreibung: Single-gene trees have failed to locate the root of the eukaryote tree because of systematic biases in sequence evolution. Structural genetic data should yield more reliable insights into deep phylogenetic relationships. We searched major protist groups for the presence or absence of a gene fusion in order to locate the root of the eukaryote tree. In striking contrast to previous molecular studies, we show that all eukaryote groups ancestrally with two cilia (bikonts) are evolutionarily derived. The root lies between bikonts and opisthokonts (animals, Fungi, Choanozoa). Amoebozoa either diverged even earlier or are sister of bikonts or (less likely) opisthokonts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stechmann, Alexandra -- Cavalier-Smith, Thomas -- New York, N.Y. -- Science. 2002 Jul 5;297(5578):89-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK. alexandra.stechmann@zoo.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12098695" target="_blank"〉PubMed〈/a〉

    Beschreibung: Plant self-incompatibility (SI) systems are unique among self/nonself recognition systems in being based on the recognition of self rather than nonself. SI in crucifer species is controlled by highly polymorphic and co-evolving genes linked in a complex. Self recognition is based on allele-specific interactions between stigma receptors and pollen ligands that result in the arrest of pollen tube development. Commonalities and differences between SI and other self/nonself discrimination systems are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nasrallah, June B -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):305-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Cornell University, Ithaca, NY 14853, USA. jbn2@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11951033" target="_blank"〉PubMed〈/a〉

    Beschreibung: The brain's earliest self-representational capacities arose as evolution found neural network solutions for coordinating and regulating inner-body signals, thereby improving behavioral strategies. Additional flexibility in organizing coherent behavioral options emerges from neural models that represent some of the brain's inner states as states of its body, while representing other signals as perceptions of the external world. Brains manipulate inner models to predict the distinct consequences in the external world of distinct behavioral options. The self thus turns out to be identifiable not with a nonphysical soul, but rather with a set of representational capacities of the physical brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Churchland, Patricia S -- New York, N.Y. -- Science. 2002 Apr 12;296(5566):308-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Philosophy Department 0119, University of California, San Diego, La Jolla, CA 92093, USA. pschurchland@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11951034" target="_blank"〉PubMed〈/a〉

    Beschreibung: In cooperatively breeding vertebrates, nonbreeding helpers raise young produced by dominant breeders. Although the evolution of cooperative breeding has often been attributed primarily to kin selection (whereby individuals gain "indirect" benefits to their fitness by assisting collateral relatives), there is increasing evidence that helpers can be unrelated to the young they are raising. Recent studies also suggest that the indirect benefits of cooperative behavior may often have been overestimated while the direct benefits of helping to the helper's own fitness have probably been underestimated. It now seems likely that the evolutionary mechanisms maintaining cooperative breeding are diverse and that, in some species, the direct benefits of helping may be sufficient to maintain cooperative societies. The benefits of cooperation in vertebrate societies may consequently show parallels with those in human societies, where cooperation between unrelated individuals is frequent and social institutions are often maintained by generalized reciprocity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clutton-Brock, Tim -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):69-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK. thcb@hermes.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11935014" target="_blank"〉PubMed〈/a〉

    Beschreibung: Many object-related actions can be recognized by their sound. We found neurons in monkey premotor cortex that discharge when the animal performs a specific action and when it hears the related sound. Most of the neurons also discharge when the monkey observes the same action. These audiovisual mirror neurons code actions independently of whether these actions are performed, heard, or seen. This discovery in the monkey homolog of Broca's area might shed light on the origin of language: audiovisual mirror neurons code abstract contents-the meaning of actions-and have the auditory access typical of human language to these contents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kohler, Evelyne -- Keysers, Christian -- Umilta, M Alessandra -- Fogassi, Leonardo -- Gallese, Vittorio -- Rizzolatti, Giacomo -- New York, N.Y. -- Science. 2002 Aug 2;297(5582):846-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Istituto di Fisiologia Umana, Universita di Parma, Italy., Dipartimento di Psicologia, Universita di Parma, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12161656" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mane of the African lion (Panthera leo) is a highly variable trait that reflects male condition and ambient temperature. We examined the consequences of this variation in a long-term study of lions in the Serengeti National Park, Tanzania. Mane darkness indicates nutrition and testosterone and influences both female choice and male-male competition. Mane length signals fighting success and only appears to influence male-male assessment. Dark-maned males enjoy longer reproductive life-spans and higher offspring survival, but they suffer higher surface temperatures, abnormal sperm, and lower food intake during hot months of the year. Maned males are hotter than females, and males have lighter and/or shorter manes in hotter seasons, years, and habitats. This phenotypic plasticity suggests that the mane will respond to forecasted increases in ambient temperature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Peyton M -- Packer, Craig -- New York, N.Y. -- Science. 2002 Aug 23;297(5585):1339-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution and Behavior, University of Minnesota, 1987 Upper Buford Circle, St. Paul, MN 55108, USA. west0302@umn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12193785" target="_blank"〉PubMed〈/a〉

    Beschreibung: Individuals are predicted to behave more altruistically and less competitively toward their relatives, because they share a relatively high proportion of their genes (e.g., one-half for siblings and one-eighth for cousins). Consequently, by helping a relative reproduce, an individual passes its genes to the next generation, increasing their Darwinian fitness. This idea, termed kin selection, has been applied to a wide range of phenomena in systems ranging from replicating molecules to humans. Nevertheless, competition between relatives can reduce, and even totally negate, the kin-selected benefits of altruism toward relatives. Recent theoretical work has clarified the processes and selective forces underlying this effect and has demonstrated the generality of the effect of competition between relatives.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Stuart A -- Pen, Ido -- Griffin, Ashleigh S -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):72-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cell, Animal and Population Biology, University of Edinburgh, Edinburgh EH9 3JT, UK. stu.west@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11935015" target="_blank"〉PubMed〈/a〉

    Beschreibung: Anopheles gambiae is the principal vector of malaria, a disease that afflicts more than 500 million people and causes more than 1 million deaths each year. Tenfold shotgun sequence coverage was obtained from the PEST strain of A. gambiae and assembled into scaffolds that span 278 million base pairs. A total of 91% of the genome was organized in 303 scaffolds; the largest scaffold was 23.1 million base pairs. There was substantial genetic variation within this strain, and the apparent existence of two haplotypes of approximately equal frequency ("dual haplotypes") in a substantial fraction of the genome likely reflects the outbred nature of the PEST strain. The sequence produced a conservative inference of more than 400,000 single-nucleotide polymorphisms that showed a markedly bimodal density distribution. Analysis of the genome sequence revealed strong evidence for about 14,000 protein-encoding transcripts. Prominent expansions in specific families of proteins likely involved in cell adhesion and immunity were noted. An expressed sequence tag analysis of genes regulated by blood feeding provided insights into the physiological adaptations of a hematophagous insect.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holt, Robert A -- Subramanian, G Mani -- Halpern, Aaron -- Sutton, Granger G -- Charlab, Rosane -- Nusskern, Deborah R -- Wincker, Patrick -- Clark, Andrew G -- Ribeiro, Jose M C -- Wides, Ron -- Salzberg, Steven L -- Loftus, Brendan -- Yandell, Mark -- Majoros, William H -- Rusch, Douglas B -- Lai, Zhongwu -- Kraft, Cheryl L -- Abril, Josep F -- Anthouard, Veronique -- Arensburger, Peter -- Atkinson, Peter W -- Baden, Holly -- de Berardinis, Veronique -- Baldwin, Danita -- Benes, Vladimir -- Biedler, Jim -- Blass, Claudia -- Bolanos, Randall -- Boscus, Didier -- Barnstead, Mary -- Cai, Shuang -- Center, Angela -- Chaturverdi, Kabir -- Christophides, George K -- Chrystal, Mathew A -- Clamp, Michele -- Cravchik, Anibal -- Curwen, Val -- Dana, Ali -- Delcher, Art -- Dew, Ian -- Evans, Cheryl A -- Flanigan, Michael -- Grundschober-Freimoser, Anne -- Friedli, Lisa -- Gu, Zhiping -- Guan, Ping -- Guigo, Roderic -- Hillenmeyer, Maureen E -- Hladun, Susanne L -- Hogan, James R -- Hong, Young S -- Hoover, Jeffrey -- Jaillon, Olivier -- Ke, Zhaoxi -- Kodira, Chinnappa -- Kokoza, Elena -- Koutsos, Anastasios -- Letunic, Ivica -- Levitsky, Alex -- Liang, Yong -- Lin, Jhy-Jhu -- Lobo, Neil F -- Lopez, John R -- Malek, Joel A -- McIntosh, Tina C -- Meister, Stephan -- Miller, Jason -- Mobarry, Clark -- Mongin, Emmanuel -- Murphy, Sean D -- O'Brochta, David A -- Pfannkoch, Cynthia -- Qi, Rong -- Regier, Megan A -- Remington, Karin -- Shao, Hongguang -- Sharakhova, Maria V -- Sitter, Cynthia D -- Shetty, Jyoti -- Smith, Thomas J -- Strong, Renee -- Sun, Jingtao -- Thomasova, Dana -- Ton, Lucas Q -- Topalis, Pantelis -- Tu, Zhijian -- Unger, Maria F -- Walenz, Brian -- Wang, Aihui -- Wang, Jian -- Wang, Mei -- Wang, Xuelan -- Woodford, Kerry J -- Wortman, Jennifer R -- Wu, Martin -- Yao, Alison -- Zdobnov, Evgeny M -- Zhang, Hongyu -- Zhao, Qi -- Zhao, Shaying -- Zhu, Shiaoping C -- Zhimulev, Igor -- Coluzzi, Mario -- della Torre, Alessandra -- Roth, Charles W -- Louis, Christos -- Kalush, Francis -- Mural, Richard J -- Myers, Eugene W -- Adams, Mark D -- Smith, Hamilton O -- Broder, Samuel -- Gardner, Malcolm J -- Fraser, Claire M -- Birney, Ewan -- Bork, Peer -- Brey, Paul T -- Venter, J Craig -- Weissenbach, Jean -- Kafatos, Fotis C -- Collins, Frank H -- Hoffman, Stephen L -- R01AI44273/AI/NIAID NIH HHS/ -- U01AI48846/AI/NIAID NIH HHS/ -- U01AI50687/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2002 Oct 4;298(5591):129-49.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Celera Genomics, 45 West Gude Drive, Rockville, MD 20850, USA. robert.holt@celera.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12364791" target="_blank"〉PubMed〈/a〉

    Beschreibung: There are two stereochemical classes of hydratase-dehydratase enzymes. Those that catalyze the addition of water to alpha, beta-unsaturated thioesters give syn addition-elimination stereochemistry, whereas those that catalyze the addition of water to conjugated carboxylate substrates give anti stereochemistry. This dichotomy could reflect different adaptive advantages or contingencies of separate evolutionary histories. Determination of the nonenzymatic stereochemistry of deuterium oxide addition to fumarate and to S-crotonyl N-acetylcysteamine has provided direct evidence for the importance of the contingencies of evolutionary history, rather than chemical efficiency, in the pathways of these hydratase-dehydratase enzymes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mohrig, J R -- Moerke, K A -- Cloutier, D L -- Lane, B D -- Person, E C -- Onasch, T B -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):527-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Carleton College, Northfield, MN 55057, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624773" target="_blank"〉PubMed〈/a〉

    Beschreibung: The human beta-globin locus control region (LCR) controls the transcription, chromatin structure, and replication timing of the entire locus. DNA replication was found to initiate in a transcription-independent manner within a region located 50 kilobases downstream of the LCR in human, mouse, and chicken cells containing the entire human beta-globin locus. However, DNA replication did not initiate within a deletion mutant locus lacking the sequences that encompass the LCR. This mutant locus replicated in the 3' to 5' direction. Thus, interactions between distantly separated sequences can be required for replication initiation, and factors mediating this interaction appear to be conserved in evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aladjem, M I -- Groudine, M -- Brody, L L -- Dieken, E S -- Fournier, R E -- Wahl, G M -- Epner, E M -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, Salk Institute, San Diego, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481774" target="_blank"〉PubMed〈/a〉

    Beschreibung: Four articulating hominid foot bones have been recovered from Sterkfontein Member 2, near Johannesburg, South Africa. They have human features in the hindfoot and strikingly apelike traits in the forefoot. While the foot is manifestly adapted for bipedalism, its most remarkable characteristic is that the great toe (hallux) is appreciably medially diverged (varus) and strongly mobile, as in apes. Possibly as old as 3.5 million years, the foot provides the first evidence that bipedal hominids were in southern Africa more than 3.0 million years ago. The bones probably belonged to an early member of Australopithecus africanus or another early hominid species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clarke, R J -- Tobias, P V -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):521-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Human Biology, University of the Witwatersrand Medical School, Johannesburg, South Africa.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624772" target="_blank"〉PubMed〈/a〉

    Beschreibung: The crystal structure of a class I aminoacyl-transfer RNA synthetase, glutamyl-tRNA synthetase (GluRS) from Thermus thermophilus, was solved and refined at 2.5 A resolution. The amino-terminal half of GluRS shows a geometrical similarity with that of Escherichia coli glutaminyl-tRNA synthetase (GlnRS) of the same subclass in class I, comprising the class I-specific Rossmann fold domain and the intervening subclass-specific alpha/beta domain. These domains were found to have two GluRS-specific, secondary-structure insertions, which then participated in the specific recognition of the D and acceptor stems of tRNA(Glu) as indicated by mutagenesis analyses based on the docking properties of GluRS and tRNA. In striking contrast to the beta-barrel structure of the GlnRS carboxyl-terminal half, the GluRS carboxyl-terminal half displayed an all-alpha-helix architecture, an alpha-helix cage, and mutagenesis analyses indicated that it had a role in the anticodon recognition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nureki, O -- Vassylyev, D G -- Katayanagi, K -- Shimizu, T -- Sekine, S -- Kigawa, T -- Miyazawa, T -- Yokoyama, S -- Morikawa, K -- New York, N.Y. -- Science. 1995 Mar 31;267(5206):1958-65.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biophysics and Biochemistry, School of Science, University of Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7701318" target="_blank"〉PubMed〈/a〉

    Beschreibung: A gene from human chromosome 11p11.2 was isolated and was shown to suppress metastasis when introduced into rat AT6.1 prostate cancer cells. Expression of this gene, designated KAI1, was reduced in human cell lines derived from metastatic prostate tumors. KAI1 specifies a protein of 267 amino acids, with four hydrophobic and presumably transmembrane domains and one large extracellular hydrophilic domain with three potential N-glycosylation sites. KAI1 is evolutionarily conserved, is expressed in many human tissues, and encodes a member of a structurally distinct family of leukocyte surface glycoproteins. Decreased expression of this gene may be involved in the malignant progression of prostate and other cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, J T -- Lamb, P W -- Rinker-Schaeffer, C W -- Vukanovic, J -- Ichikawa, T -- Isaacs, J T -- Barrett, J C -- CA 58236/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 May 12;268(5212):884-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Carcinogenesis, National Institute of Environmental Health Sciences, National Institute of Health, Research Triangle Park, NC 27709, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754374" target="_blank"〉PubMed〈/a〉

    Beschreibung: A bacterial spore was revived, cultured, and identified from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber. Rigorous surface decontamination of the amber and aseptic procedures were used during the recovery of the bacterium. Several lines of evidence indicated that the isolated bacterium was of ancient origin and not an extant contaminant. The characteristic enzymatic, biochemical, and 16S ribosomal DNA profiles indicated that the ancient bacterium is most closely related to extant Bacillus sphaericus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cano, R J -- Borucki, M K -- New York, N.Y. -- Science. 1995 May 19;268(5213):1060-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Sciences, California Polytechnic State University, San Luis Obispo 93407, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7538699" target="_blank"〉PubMed〈/a〉

    Beschreibung: By presenting antigenic peptides to T lymphocytes, major histocompatibility complex (MHC) class I molecules play important roles in the human immune system. Knowledge is limited on the evolutionary history of human MHC class I-related molecules. An expressed class I gene, MR1, has now been identified on human chromosome 1q25, outside the MHC. In contrast to other known human divergent class I genes, MR1 encodes peptide-binding domains similar to those encoded by human leukocyte antigen (HLA) class I genes on chromosome 6 and by nonmammalian classical MHC class I genes. This gene may thus contribute to understanding the evolution of the MHC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hashimoto, K -- Hirai, M -- Kurosawa, Y -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):693-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Comprehensive Medical Science, Fujita Health University, Aichi, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624800" target="_blank"〉PubMed〈/a〉

    Beschreibung: The chloroplasts of most dinoflagellates are unusual in that they are surrounded by three membranes and contain the carotenoid peridinin. The ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO) in dinoflagellate chloroplasts was found here to also be unusual. Unlike other eukaryotes, dinoflagellates containing peridinin use a form of RuBisCO (form II) previously found only in some species of proteobacteria. Furthermore, this RuBisCO is not encoded in the chloroplast DNA, as is the case in other organisms, but is encoded by the nuclear DNA. The unusual nature of this enzyme and location of its gene support the idea that dinoflagellate chloroplasts may have had a distinctive evolutionary origin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morse, D -- Salois, P -- Markovic, P -- Hastings, J W -- 2R01-GM-19536/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 16;268(5217):1622-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche en Biologie Vegetal, Universite de Montreal, PQ, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7777861" target="_blank"〉PubMed〈/a〉

    Beschreibung: An RNA has been selected that rapidly aminoacylates its 2'(3') terminus when provided with phenylalanyl-adenosine monophosphate. That is, the RNA accelerates the same aminoacyl group transfer catalyzed by protein aminoacyl-transfer RNA synthetases. The best characterized RNA reaction requires both Mg2+ and Ca2+. These results confirm a necessary prediction of the RNA world hypothesis and represent efficient RNA reaction (〉 or = 10(5) times accelerated) at a carbonyl carbon, exemplifying a little explored type of RNA catalysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Illangasekare, M -- Sanchez, G -- Nickles, T -- Yarus, M -- GM30881/GM/NIGMS NIH HHS/ -- GM48080/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Feb 3;267(5198):643-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular, and Developmental Biology, University of Colorado, Boulder 80309-0347.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7530860" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pineal opsin (P-opsin), an opsin from chick that is highly expressed in pineal but is not detectable in retina, was cloned by the polymerase chain reaction. It is likely that the P-opsin lineage diverged from the retinal opsins early in opsin evolution. The amino acid sequence of P-opsin is 42 to 46 percent identical to that of the retinal opsins. P-opsin is a seven-membrane spanning, G protein-linked receptor with a Schiff-base lysine in the seventh membrane span and a Schiff-base counterion in the third membrane span. The primary sequence of P-opsin suggests that it will be maximally sensitive to approximately 500-nanometer light and produce a slow and prolonged phototransduction response consistent with the nonvisual function of pineal photoreception.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Max, M -- McKinnon, P J -- Seidenman, K J -- Barrett, R K -- Applebury, M L -- Takahashi, J S -- Margolskee, R F -- EYO8467/EY/NEI NIH HHS/ -- MH10287/MH/NIMH NIH HHS/ -- MH39592/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 Mar 10;267(5203):1502-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Roche Institute of Molecular Biology, Roche Research Center, Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7878470" target="_blank"〉PubMed〈/a〉

    Beschreibung: The suspension-feeding metazoan subkingdom Lophophorata exhibits characteristics of both deuterostomes and protostomes. Because the morphology and embryology of lophophorates are phylogenetically ambiguous, their origin is a major unsolved problem of metazoan phylogenetics. The complete 18S ribosomal DNA sequences of all three lophophorate phyla were obtained and analyzed to clarify the phylogenetic relationships of this subkingdom. Sequence analyses show that lophophorates are protostomes closely related to mollusks and annelids. This conclusion deviates from the commonly held view of deuterostome affinity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halanych, K M -- Bacheller, J D -- Aguinaldo, A M -- Liva, S M -- Hillis, D M -- Lake, J A -- New York, N.Y. -- Science. 1995 Mar 17;267(5204):1641-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7886451" target="_blank"〉PubMed〈/a〉
