Description: Sorghum, an African grass related to sugar cane and maize, is grown for food, feed, fibre and fuel. We present an initial analysis of the approximately 730-megabase Sorghum bicolor (L.) Moench genome, placing approximately 98% of genes in their chromosomal context using whole-genome shotgun sequence validated by genetic, physical and syntenic information. Genetic recombination is largely confined to about one-third of the sorghum genome with gene order and density similar to those of rice. Retrotransposon accumulation in recombinationally recalcitrant heterochromatin explains the approximately 75% larger genome size of sorghum compared with rice. Although gene and repetitive DNA distributions have been preserved since palaeopolyploidization approximately 70 million years ago, most duplicated gene sets lost one member before the sorghum-rice divergence. Concerted evolution makes one duplicated chromosomal segment appear to be only a few million years old. About 24% of genes are grass-specific and 7% are sorghum-specific. Recent gene and microRNA duplications may contribute to sorghum's drought tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paterson, Andrew H -- Bowers, John E -- Bruggmann, Remy -- Dubchak, Inna -- Grimwood, Jane -- Gundlach, Heidrun -- Haberer, Georg -- Hellsten, Uffe -- Mitros, Therese -- Poliakov, Alexander -- Schmutz, Jeremy -- Spannagl, Manuel -- Tang, Haibao -- Wang, Xiyin -- Wicker, Thomas -- Bharti, Arvind K -- Chapman, Jarrod -- Feltus, F Alex -- Gowik, Udo -- Grigoriev, Igor V -- Lyons, Eric -- Maher, Christopher A -- Martis, Mihaela -- Narechania, Apurva -- Otillar, Robert P -- Penning, Bryan W -- Salamov, Asaf A -- Wang, Yu -- Zhang, Lifang -- Carpita, Nicholas C -- Freeling, Michael -- Gingle, Alan R -- Hash, C Thomas -- Keller, Beat -- Klein, Patricia -- Kresovich, Stephen -- McCann, Maureen C -- Ming, Ray -- Peterson, Daniel G -- Mehboob-ur-Rahman -- Ware, Doreen -- Westhoff, Peter -- Mayer, Klaus F X -- Messing, Joachim -- Rokhsar, Daniel S -- England -- Nature. 2009 Jan 29;457(7229):551-6. doi: 10.1038/nature07723.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia 30602, USA. paterson@uga.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19189423" target="_blank"〉PubMed〈/a〉

Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

Description: Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change. These broadly distributed primary producers belong to an anciently diverged sister clade to land plants. Although Micromonas isolates have high 18S ribosomal RNA gene identity, we found that genomes from two isolates shared only 90% of their predicted genes. Their independent evolutionary paths were emphasized by distinct riboswitch arrangements as well as the discovery of intronic repeat elements in one isolate, and in metagenomic data, but not in other genomes. Divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolates differently than the core genes. Analyses of the Micromonas genomes offer valuable insights into ecological differentiation and the dynamic nature of early plant evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worden, Alexandra Z -- Lee, Jae-Hyeok -- Mock, Thomas -- Rouze, Pierre -- Simmons, Melinda P -- Aerts, Andrea L -- Allen, Andrew E -- Cuvelier, Marie L -- Derelle, Evelyne -- Everett, Meredith V -- Foulon, Elodie -- Grimwood, Jane -- Gundlach, Heidrun -- Henrissat, Bernard -- Napoli, Carolyn -- McDonald, Sarah M -- Parker, Micaela S -- Rombauts, Stephane -- Salamov, Aasf -- Von Dassow, Peter -- Badger, Jonathan H -- Coutinho, Pedro M -- Demir, Elif -- Dubchak, Inna -- Gentemann, Chelle -- Eikrem, Wenche -- Gready, Jill E -- John, Uwe -- Lanier, William -- Lindquist, Erika A -- Lucas, Susan -- Mayer, Klaus F X -- Moreau, Herve -- Not, Fabrice -- Otillar, Robert -- Panaud, Olivier -- Pangilinan, Jasmyn -- Paulsen, Ian -- Piegu, Benoit -- Poliakov, Aaron -- Robbens, Steven -- Schmutz, Jeremy -- Toulza, Eve -- Wyss, Tania -- Zelensky, Alexander -- Zhou, Kemin -- Armbrust, E Virginia -- Bhattacharya, Debashish -- Goodenough, Ursula W -- Van de Peer, Yves -- Grigoriev, Igor V -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):268-72. doi: 10.1126/science.1167222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95039 USA. azworden@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359590" target="_blank"〉PubMed〈/a〉

Description: Eucalypts are the world's most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have made them a global renewable resource of fibre and energy. We sequenced and assembled 〉94% of the 640-megabase genome of Eucalyptus grandis. Of 36,376 predicted protein-coding genes, 34% occur in tandem duplications, the largest proportion thus far in plant genomes. Eucalyptus also shows the highest diversity of genes for specialized metabolites such as terpenes that act as chemical defence and provide unique pharmaceutical oils. Genome sequencing of the E. grandis sister species E. globulus and a set of inbred E. grandis tree genomes reveals dynamic genome evolution and hotspots of inbreeding depression. The E. grandis genome is the first reference for the eudicot order Myrtales and is placed here sister to the eurosids. This resource expands our understanding of the unique biology of large woody perennials and provides a powerful tool to accelerate comparative biology, breeding and biotechnology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myburg, Alexander A -- Grattapaglia, Dario -- Tuskan, Gerald A -- Hellsten, Uffe -- Hayes, Richard D -- Grimwood, Jane -- Jenkins, Jerry -- Lindquist, Erika -- Tice, Hope -- Bauer, Diane -- Goodstein, David M -- Dubchak, Inna -- Poliakov, Alexandre -- Mizrachi, Eshchar -- Kullan, Anand R K -- Hussey, Steven G -- Pinard, Desre -- van der Merwe, Karen -- Singh, Pooja -- van Jaarsveld, Ida -- Silva-Junior, Orzenil B -- Togawa, Roberto C -- Pappas, Marilia R -- Faria, Danielle A -- Sansaloni, Carolina P -- Petroli, Cesar D -- Yang, Xiaohan -- Ranjan, Priya -- Tschaplinski, Timothy J -- Ye, Chu-Yu -- Li, Ting -- Sterck, Lieven -- Vanneste, Kevin -- Murat, Florent -- Soler, Marcal -- Clemente, Helene San -- Saidi, Naijib -- Cassan-Wang, Hua -- Dunand, Christophe -- Hefer, Charles A -- Bornberg-Bauer, Erich -- Kersting, Anna R -- Vining, Kelly -- Amarasinghe, Vindhya -- Ranik, Martin -- Naithani, Sushma -- Elser, Justin -- Boyd, Alexander E -- Liston, Aaron -- Spatafora, Joseph W -- Dharmwardhana, Palitha -- Raja, Rajani -- Sullivan, Christopher -- Romanel, Elisson -- Alves-Ferreira, Marcio -- Kulheim, Carsten -- Foley, William -- Carocha, Victor -- Paiva, Jorge -- Kudrna, David -- Brommonschenkel, Sergio H -- Pasquali, Giancarlo -- Byrne, Margaret -- Rigault, Philippe -- Tibbits, Josquin -- Spokevicius, Antanas -- Jones, Rebecca C -- Steane, Dorothy A -- Vaillancourt, Rene E -- Potts, Brad M -- Joubert, Fourie -- Barry, Kerrie -- Pappas, Georgios J -- Strauss, Steven H -- Jaiswal, Pankaj -- Grima-Pettenati, Jacqueline -- Salse, Jerome -- Van de Peer, Yves -- Rokhsar, Daniel S -- Schmutz, Jeremy -- England -- Nature. 2014 Jun 19;510(7505):356-62. doi: 10.1038/nature13308.

Description: Bacteriophages, herpesviruses, and other large double-stranded DNA (dsDNA) viruses contain molecular machines that pump DNA into preassembled procapsids, generating internal capsid pressures exceeding, by 10-fold, that of bottled champagne. A 17 angstrom resolution asymmetric reconstruction of the infectious P22 virion reveals that tightly spooled DNA about the portal dodecamer forces a conformation that is significantly different from that observed in isolated portals assembled from ectopically expressed protein. We propose that the tight dsDNA spooling activates the switch that signals the headful chromosome packing density to the particle exterior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lander, Gabriel C -- Tang, Liang -- Casjens, Sherwood R -- Gilcrease, Eddie B -- Prevelige, Peter -- Poliakov, Anton -- Potter, Clinton S -- Carragher, Bridget -- Johnson, John E -- RR17573/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 23;312(5781):1791-5.

Description: We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. More than 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication, and gross chromosomal rearrangement appear to proceed substantially more slowly in Populus than in Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average from 1.4 to 1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with lignocellulosic wall biosynthesis, meristem development, disease resistance, and metabolite transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tuskan, G A -- Difazio, S -- Jansson, S -- Bohlmann, J -- Grigoriev, I -- Hellsten, U -- Putnam, N -- Ralph, S -- Rombauts, S -- Salamov, A -- Schein, J -- Sterck, L -- Aerts, A -- Bhalerao, R R -- Bhalerao, R P -- Blaudez, D -- Boerjan, W -- Brun, A -- Brunner, A -- Busov, V -- Campbell, M -- Carlson, J -- Chalot, M -- Chapman, J -- Chen, G-L -- Cooper, D -- Coutinho, P M -- Couturier, J -- Covert, S -- Cronk, Q -- Cunningham, R -- Davis, J -- Degroeve, S -- Dejardin, A -- Depamphilis, C -- Detter, J -- Dirks, B -- Dubchak, I -- Duplessis, S -- Ehlting, J -- Ellis, B -- Gendler, K -- Goodstein, D -- Gribskov, M -- Grimwood, J -- Groover, A -- Gunter, L -- Hamberger, B -- Heinze, B -- Helariutta, Y -- Henrissat, B -- Holligan, D -- Holt, R -- Huang, W -- Islam-Faridi, N -- Jones, S -- Jones-Rhoades, M -- Jorgensen, R -- Joshi, C -- Kangasjarvi, J -- Karlsson, J -- Kelleher, C -- Kirkpatrick, R -- Kirst, M -- Kohler, A -- Kalluri, U -- Larimer, F -- Leebens-Mack, J -- Leple, J-C -- Locascio, P -- Lou, Y -- Lucas, S -- Martin, F -- Montanini, B -- Napoli, C -- Nelson, D R -- Nelson, C -- Nieminen, K -- Nilsson, O -- Pereda, V -- Peter, G -- Philippe, R -- Pilate, G -- Poliakov, A -- Razumovskaya, J -- Richardson, P -- Rinaldi, C -- Ritland, K -- Rouze, P -- Ryaboy, D -- Schmutz, J -- Schrader, J -- Segerman, B -- Shin, H -- Siddiqui, A -- Sterky, F -- Terry, A -- Tsai, C-J -- Uberbacher, E -- Unneberg, P -- Vahala, J -- Wall, K -- Wessler, S -- Yang, G -- Yin, T -- Douglas, C -- Marra, M -- Sandberg, G -- Van de Peer, Y -- Rokhsar, D -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1596-604.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Sciences Division, Oak Ridge National Laboratory, Oak Ridge, TN 37831, USA. gtk@ornl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973872" target="_blank"〉PubMed〈/a〉

Description: Cells have self-organizing properties that control their behavior in complex tissues. Contact between cells expressing either B-type Eph receptors or their transmembrane ephrin ligands initiates bidirectional signals that regulate cell positioning. However, simultaneously investigating how information is processed in two interacting cell types remains a challenge. We implemented a proteomic strategy to systematically determine cell-specific signaling networks underlying EphB2- and ephrin-B1-controlled cell sorting. Quantitative mass spectrometric analysis of mixed populations of EphB2- and ephrin-B1-expressing cells that were labeled with different isotopes revealed cell-specific tyrosine phosphorylation events. Functional associations between these phosphotyrosine signaling networks and cell sorting were established with small interfering RNA screening. Data-driven network modeling revealed that signaling between mixed EphB2- and ephrin-B1-expressing cells is asymmetric and that the distinct cell types use different tyrosine kinases and targets to process signals induced by cell-cell contact. We provide systems- and cell-specific network models of contact-initiated signaling between two distinct cell types.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jorgensen, Claus -- Sherman, Andrew -- Chen, Ginny I -- Pasculescu, Adrian -- Poliakov, Alexei -- Hsiung, Marilyn -- Larsen, Brett -- Wilkinson, David G -- Linding, Rune -- Pawson, Tony -- MC_U117532048/Medical Research Council/United Kingdom -- MOP-6849/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1502-9. doi: 10.1126/science.1176615.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute (SLRI), Mount Sinai Hospital, Toronto M5G 1X5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007894" target="_blank"〉PubMed〈/a〉
