    Changes in regulation of a transcription factor lead to autogamy in cultivated tomatoes (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-27
    Description: We report the cloning of Style2.1, the major quantitative trait locus responsible for a key floral attribute (style length) associated with the evolution of self-pollination in cultivated tomatoes. The gene encodes a putative transcription factor that regulates cell elongation in developing styles. The transition from cross-pollination to self-pollination was accompanied, not by a change in the STYLE2.1 protein, but rather by a mutation in the Style2.1 promoter that results in a down-regulation of Style2.1 expression during flower development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Kai-Yi -- Cong, Bin -- Wing, Rod -- Vrebalov, Julia -- Tanksley, Steven D -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):643-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Breeding and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962563" target="_blank"〉PubMed〈/a〉

    Evolutionary formation of new centromeres in macaque (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-14
    Description: A systematic fluorescence in situ hybridization comparison of macaque and human synteny organization disclosed five additional macaque evolutionary new centromeres (ENCs) for a total of nine ENCs. To understand the dynamics of ENC formation and progression, we compared the ENC of macaque chromosome 4 with the human orthologous region, at 6q24.3, that conserves the ancestral genomic organization. A 250-kilobase segment was extensively duplicated around the macaque centromere. These duplications were strictly intrachromosomal. Our results suggest that novel centromeres may trigger only local duplication activity and that the absence of genes in the seeding region may have been important in ENC maintenance and progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ventura, Mario -- Antonacci, Francesca -- Cardone, Maria Francesca -- Stanyon, Roscoe -- D'Addabbo, Pietro -- Cellamare, Angelo -- Sprague, L James -- Eichler, Evan E -- Archidiacono, Nicoletta -- Rocchi, Mariano -- GM58815/GM/NIGMS NIH HHS/ -- HG002385/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):243-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Microbiology, University of Bari, 70126 Bari, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431171" target="_blank"〉PubMed〈/a〉

    Permuted tRNA genes expressed via a circular RNA intermediate in Cyanidioschyzon merolae (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-20
    Description: A computational analysis of the nuclear genome of a red alga, Cyanidioschyzon merolae, identified 11 transfer RNA (tRNA) genes in which the 3' half of the tRNA lies upstream of the 5' half in the genome. We verified that these genes are expressed and produce mature tRNAs that are aminoacylated. Analysis of tRNA-processing intermediates for these genes indicates an unusual processing pathway in which the termini of the tRNA precursor are ligated, resulting in formation of a characteristic circular RNA intermediate that is then processed at the acceptor stem to generate the correct termini.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soma, Akiko -- Onodera, Akinori -- Sugahara, Junichi -- Kanai, Akio -- Yachie, Nozomu -- Tomita, Masaru -- Kawamura, Fujio -- Sekine, Yasuhiko -- New York, N.Y. -- Science. 2007 Oct 19;318(5849):450-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Science, College of Science, Rikkyo (St. Paul's) University, Toshima, Tokyo 171-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17947580" target="_blank"〉PubMed〈/a〉

    Developmentally regulated activation of a SINE B2 repeat as a domain boundary in organogenesis (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-07-14
    Description: The temporal and spatial regulation of gene expression in mammalian development is linked to the establishment of functional chromatin domains. Here, we report that tissue-specific transcription of a retrotransposon repeat in the murine growth hormone locus is required for gene activation. This repeat serves as a boundary to block the influence of repressive chromatin modifications. The repeat element is able to generate short, overlapping Pol II-and Pol III-driven transcripts, both of which are necessary and sufficient to enable a restructuring of the regulated locus into nuclear compartments. These data suggest that transcription of interspersed repetitive sequences may represent a developmental strategy for the establishment of functionally distinct domains within the mammalian genome to control gene activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lunyak, Victoria V -- Prefontaine, Gratien G -- Nunez, Esperanza -- Cramer, Thorsten -- Ju, Bong-Gun -- Ohgi, Kenneth A -- Hutt, Kasey -- Roy, Rosa -- Garcia-Diaz, Angel -- Zhu, Xiaoyan -- Yung, Yun -- Montoliu, Lluis -- Glass, Christopher K -- Rosenfeld, Michael G -- New York, N.Y. -- Science. 2007 Jul 13;317(5835):248-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, School of Medicine, University of California, San Diego, 9500 Gilman Drive, Room 345, La Jolla, CA 92093-0648, USA. vlunyak@uscd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17626886" target="_blank"〉PubMed〈/a〉

    HIV-1 proviral DNA excision using an evolved recombinase (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-30
    Description: HIV-1 integrates into the host chromosome and persists as a provirus flanked by long terminal repeats (LTRs). To date, treatment regimens primarily target the virus enzymes or virus-cell fusion, but not the integrated provirus. We report here the substrate-linked protein evolution of a tailored recombinase that recognizes an asymmetric sequence within an HIV-1 LTR. This evolved recombinase efficiently excised integrated HIV proviral DNA from the genome of infected cells. Although a long way from use in the clinic, we speculate that this type of technology might be adapted in future antiretroviral therapies, among other possible uses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sarkar, Indrani -- Hauber, Ilona -- Hauber, Joachim -- Buchholz, Frank -- New York, N.Y. -- Science. 2007 Jun 29;316(5833):1912-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute for Molecular Cell Biology and Genetics, Pfotenhauerstrasse 108, D-01307 Dresden, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17600219" target="_blank"〉PubMed〈/a〉

    A systems approach to measuring the binding energy landscapes of transcription factors (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-16
    Description: A major goal of systems biology is to predict the function of biological networks. Although network topologies have been successfully determined in many cases, the quantitative parameters governing these networks generally have not. Measuring affinities of molecular interactions in high-throughput format remains problematic, especially for transient and low-affinity interactions. We describe a high-throughput microfluidic platform that measures such properties on the basis of mechanical trapping of molecular interactions. With this platform we characterized DNA binding energy landscapes for four eukaryotic transcription factors; these landscapes were used to test basic assumptions about transcription factor binding and to predict their in vivo function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maerkl, Sebastian J -- Quake, Stephen R -- New York, N.Y. -- Science. 2007 Jan 12;315(5809):233-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biochemistry and Molecular Biophysics Option, California Institute of Technology, 1200 East California Boulevard, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17218526" target="_blank"〉PubMed〈/a〉

    The Piwi-piRNA pathway provides an adaptive defense in the transposon arms race (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-11-03
    Description: Increasingly complex networks of small RNAs act through RNA-interference (RNAi) pathways to regulate gene expression, to mediate antiviral responses, to organize chromosomal domains, and to restrain the spread of selfish genetic elements. Historically, RNAi has been defined as a response to double-stranded RNA. However, some small RNA species may not arise from double-stranded RNA precursors. Yet, like microRNAs and small interfering RNAs, such species guide Argonaute proteins to silencing targets through complementary base-pairing. Silencing can be achieved by corecruitment of accessory factors or through the activity of Argonaute itself, which often has endonucleolytic activity. As a specific and adaptive regulatory system, RNAi is used throughout eukarya, which indicates a long evolutionary history. A likely function of RNAi throughout that history is to protect the genome from both pathogenic and parasitic invaders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aravin, Alexei A -- Hannon, Gregory J -- Brennecke, Julius -- New York, N.Y. -- Science. 2007 Nov 2;318(5851):761-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Watson School of Biological Sciences, Howard Hughes Medical Institute, 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/17975059" target="_blank"〉PubMed〈/a〉

    A hexanucleotide element directs microRNA nuclear import (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-06
    Description: MicroRNAs (miRNAs) negatively regulate partially complementary target messenger RNAs. Target selection in animals is dictated primarily by sequences at the miRNA 5' end. We demonstrated that despite their small size, specific miRNAs contain additional sequence elements that control their posttranscriptional behavior, including their subcellular localization. We showed that human miR-29b, in contrast to other studied animal miRNAs, is predominantly localized to the nucleus. The distinctive hexanucleotide terminal motif of miR-29b acts as a transferable nuclear localization element that directs nuclear enrichment of miRNAs or small interfering RNAs to which it is attached. Our results indicate that miRNAs sharing common 5' sequences, considered to be largely redundant, might have distinct functions because of the influence of cis-acting regulatory motifs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hwang, Hun-Way -- Wentzel, Erik A -- Mendell, Joshua T -- New York, N.Y. -- Science. 2007 Jan 5;315(5808):97-100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Human Genetics and Molecular Biology, McKusick-Nathans Institute of Genetic Medicine, 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/17204650" target="_blank"〉PubMed〈/a〉

    Sponge paleogenomics reveals an ancient role for carbonic anhydrase in skeletogenesis (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-02
    Description: Sponges (phylum Porifera) were prolific reef-building organisms during the Paleozoic and Mesozoic approximately 542 to 65 million years ago. These ancient animals inherited components of the first multicellular skeletogenic toolkit from the last common ancestor of the Metazoa. Using a paleogenomics approach, including gene- and protein-expression techniques and phylogenetic reconstruction, we show that a molecular component of this toolkit was the precursor to the alpha-carbonic anhydrases (alpha-CAs), a gene family used by extant animals in a variety of fundamental physiological processes. We used the coralline demosponge Astrosclera willeyana, a "living fossil" that has survived from the Mesozoic, to provide insight into the evolution of the ability to biocalcify, and show that the alpha-CA family expanded from a single ancestral gene through several independent gene-duplication events in sponges and eumetazoans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jackson, Daniel J -- Macis, Luciana -- Reitner, Joachim -- Degnan, Bernard M -- Worheide, Gert -- New York, N.Y. -- Science. 2007 Jun 29;316(5833):1893-5.
