    Description: We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The genome encodes about 23,300 genes, including many previously thought to be vertebrate innovations or known only outside the deuterostomes. This echinoderm genome provides an evolutionary outgroup for the chordates and yields insights into the evolution of deuterostomes.〈br /〉〈br /〉〈a

    Description: Aortic aneurysm and dissection are manifestations of Marfan syndrome (MFS), a disorder caused by mutations in the gene that encodes fibrillin-1. Selected manifestations of MFS reflect excessive signaling by the transforming growth factor-beta (TGF-beta) family of cytokines. We show that aortic aneurysm in a mouse model of MFS is associated with increased TGF-beta signaling and can be prevented by TGF-beta antagonists such as TGF-beta-neutralizing antibody or the angiotensin II type 1 receptor (AT1) blocker, losartan. AT1 antagonism also partially reversed noncardiovascular manifestations of MFS, including impaired alveolar septation. These data suggest that losartan, a drug already in clinical use for hypertension, merits investigation as a therapeutic strategy for patients with MFS and has the potential to prevent the major life-threatening manifestation of this disorder.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1482474/" 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/PMC1482474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habashi, Jennifer P -- Judge, Daniel P -- Holm, Tammy M -- Cohn, Ronald D -- Loeys, Bart L -- Cooper, Timothy K -- Myers, Loretha -- Klein, Erin C -- Liu, Guosheng -- Calvi, Carla -- Podowski, Megan -- Neptune, Enid R -- Halushka, Marc K -- Bedja, Djahida -- Gabrielson, Kathleen -- Rifkin, Daniel B -- Carta, Luca -- Ramirez, Francesco -- Huso, David L -- Dietz, Harry C -- K08 HL067056/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):117-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pediatrics, 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/16601194" target="_blank"〉PubMed〈/a〉

    Description: Leguminous plants (such as peas and soybeans) and rhizobial soil bacteria are symbiotic partners that communicate through molecular signaling pathways, resulting in the formation of nodules on legume roots and occasionally stems that house nitrogen-fixing bacteria. Nodule formation has been assumed to be exclusively initiated by the binding of bacterial, host-specific lipochito-oligosaccharidic Nod factors, encoded by the nodABC genes, to kinase-like receptors of the plant. Here we show by complete genome sequencing of two symbiotic, photosynthetic, Bradyrhizobium strains, BTAi1 and ORS278, that canonical nodABC genes and typical lipochito-oligosaccharidic Nod factors are not required for symbiosis in some legumes. Mutational analyses indicated that these unique rhizobia use an alternative pathway to initiate symbioses, where a purine derivative may play a key role in triggering nodule formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giraud, Eric -- Moulin, Lionel -- Vallenet, David -- Barbe, Valerie -- Cytryn, Eddie -- Avarre, Jean-Christophe -- Jaubert, Marianne -- Simon, Damien -- Cartieaux, Fabienne -- Prin, Yves -- Bena, Gilles -- Hannibal, Laure -- Fardoux, Joel -- Kojadinovic, Mila -- Vuillet, Laurie -- Lajus, Aurelie -- Cruveiller, Stephane -- Rouy, Zoe -- Mangenot, Sophie -- Segurens, Beatrice -- Dossat, Carole -- Franck, William L -- Chang, Woo-Suk -- Saunders, Elizabeth -- Bruce, David -- Richardson, Paul -- Normand, Philippe -- Dreyfus, Bernard -- Pignol, David -- Stacey, Gary -- Emerich, David -- Vermeglio, Andre -- Medigue, Claudine -- Sadowsky, Michael -- New York, N.Y. -- Science. 2007 Jun 1;316(5829):1307-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche pour le Developpement, Centre de Cooperation International en Recherche Agronomique pour le Developpement, Institut National de la Recherche Agronomique, Universite Montpellier 2, France. giraud@mpl.ird.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17540897" target="_blank"〉PubMed〈/a〉

    Description: Glioblastoma multiforme (GBM) is the most common and lethal type of brain cancer. To identify the genetic alterations in GBMs, we sequenced 20,661 protein coding genes, determined the presence of amplifications and deletions using high-density oligonucleotide arrays, and performed gene expression analyses using next-generation sequencing technologies in 22 human tumor samples. This comprehensive analysis led to the discovery of a variety of genes that were not known to be altered in GBMs. Most notably, we found recurrent mutations in the active site of isocitrate dehydrogenase 1 (IDH1) in 12% of GBM patients. Mutations in IDH1 occurred in a large fraction of young patients and in most patients with secondary GBMs and were associated with an increase in overall survival. These studies demonstrate the value of unbiased genomic analyses in the characterization of human brain cancer and identify a potentially useful genetic alteration for the classification and targeted therapy of GBMs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820389/" 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/PMC2820389/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, D Williams -- Jones, Sian -- Zhang, Xiaosong -- Lin, Jimmy Cheng-Ho -- Leary, Rebecca J -- Angenendt, Philipp -- Mankoo, Parminder -- Carter, Hannah -- Siu, I-Mei -- Gallia, Gary L -- Olivi, Alessandro -- McLendon, Roger -- Rasheed, B Ahmed -- Keir, Stephen -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Busam, Dana A -- Tekleab, Hanna -- Diaz, Luis A Jr -- Hartigan, James -- Smith, Doug R -- Strausberg, Robert L -- Marie, Suely Kazue Nagahashi -- Shinjo, Sueli Mieko Oba -- Yan, Hai -- Riggins, Gregory J -- Bigner, Darell D -- Karchin, Rachel -- Papadopoulos, Nick -- Parmigiani, Giovanni -- Vogelstein, Bert -- Velculescu, Victor E -- Kinzler, Kenneth W -- 5P50-NS-20023/NS/NINDS NIH HHS/ -- CA09547/CA/NCI NIH HHS/ -- CA108786/CA/NCI NIH HHS/ -- CA11898/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- NS052507/NS/NINDS NIH HHS/ -- P50 CA062924/CA/NCI NIH HHS/ -- P50 CA062924-160017/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-04/CA/NCI NIH HHS/ -- R01 CA140316/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37 CA043460-27/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-13/CA/NCI NIH HHS/ -- R37 CA057345-17/CA/NCI NIH HHS/ -- R37 CA057345-18/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1807-12. doi: 10.1126/science.1164382.

    Description: The genome of the eukaryotic protist Giardia lamblia, an important human intestinal parasite, is compact in structure and content, contains few introns or mitochondrial relics, and has simplified machinery for DNA replication, transcription, RNA processing, and most metabolic pathways. Protein kinases comprise the single largest protein class and reflect Giardia's requirement for a complex signal transduction network for coordinating differentiation. Lateral gene transfer from bacterial and archaeal donors has shaped Giardia's genome, and previously unknown gene families, for example, cysteine-rich structural proteins, have been discovered. Unexpectedly, the genome shows little evidence of heterozygosity, supporting recent speculations that this organism is sexual. This genome sequence will not only be valuable for investigating the evolution of eukaryotes, but will also be applied to the search for new therapeutics for this parasite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrison, Hilary G -- McArthur, Andrew G -- Gillin, Frances D -- Aley, Stephen B -- Adam, Rodney D -- Olsen, Gary J -- Best, Aaron A -- Cande, W Zacheus -- Chen, Feng -- Cipriano, Michael J -- Davids, Barbara J -- Dawson, Scott C -- Elmendorf, Heidi G -- Hehl, Adrian B -- Holder, Michael E -- Huse, Susan M -- Kim, Ulandt U -- Lasek-Nesselquist, Erica -- Manning, Gerard -- Nigam, Anuranjini -- Nixon, Julie E J -- Palm, Daniel -- Passamaneck, Nora E -- Prabhu, Anjali -- Reich, Claudia I -- Reiner, David S -- Samuelson, John -- Svard, Staffan G -- Sogin, Mitchell L -- AI42488/AI/NIAID NIH HHS/ -- AI43273/AI/NIAID NIH HHS/ -- AI51687/AI/NIAID NIH HHS/ -- R01 AI043273/AI/NIAID NIH HHS/ -- R01 AI048082/AI/NIAID NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-01/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 28;317(5846):1921-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Biological Laboratory, Woods Hole, MA 02543-1015, USA. morrison@mbl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17901334" target="_blank"〉PubMed〈/a〉

    Description: The inflammatory bowel diseases Crohn's disease and ulcerative colitis are common, chronic disorders that cause abdominal pain, diarrhea, and gastrointestinal bleeding. To identify genetic factors that might contribute to these disorders, we performed a genome-wide association study. We found a highly significant association between Crohn's disease and the IL23R gene on chromosome 1p31, which encodes a subunit of the receptor for the proinflammatory cytokine interleukin-23. An uncommon coding variant (rs11209026, c.1142G〉A, p.Arg381Gln) confers strong protection against Crohn's disease, and additional noncoding IL23R variants are independently associated. Replication studies confirmed IL23R associations in independent cohorts of patients with Crohn's disease or ulcerative colitis. These results and previous studies on the proinflammatory role of IL-23 prioritize this signaling pathway as a therapeutic target in inflammatory bowel disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410764/" 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/PMC4410764/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duerr, Richard H -- Taylor, Kent D -- Brant, Steven R -- Rioux, John D -- Silverberg, Mark S -- Daly, Mark J -- Steinhart, A Hillary -- Abraham, Clara -- Regueiro, Miguel -- Griffiths, Anne -- Dassopoulos, Themistocles -- Bitton, Alain -- Yang, Huiying -- Targan, Stephan -- Datta, Lisa Wu -- Kistner, Emily O -- Schumm, L Philip -- Lee, Annette T -- Gregersen, Peter K -- Barmada, M Michael -- Rotter, Jerome I -- Nicolae, Dan L -- Cho, Judy H -- DK62413/DK/NIDDK NIH HHS/ -- DK62420/DK/NIDDK NIH HHS/ -- DK62422/DK/NIDDK NIH HHS/ -- DK62423/DK/NIDDK NIH HHS/ -- DK62429/DK/NIDDK NIH HHS/ -- DK62431/DK/NIDDK NIH HHS/ -- DK62432/DK/NIDDK NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- P30 DK063491-019004/DK/NIDDK NIH HHS/ -- P30 DK063491-029004/DK/NIDDK NIH HHS/ -- P30 DK063491-039004/DK/NIDDK NIH HHS/ -- P30 DK063491-049004/DK/NIDDK NIH HHS/ -- U01 DK062420/DK/NIDDK NIH HHS/ -- U01 DK062422/DK/NIDDK NIH HHS/ -- U01 DK062423/DK/NIDDK NIH HHS/ -- U01 DK062429/DK/NIDDK NIH HHS/ -- U01 DK062432/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1461-3.

    Description: CD4+ T helper 1 (TH1) cells are important mediators of inflammation and are regulated by numerous pathways, including the negative immune receptor Tim-3. We found that Tim-3 is constitutively expressed on cells of the innate immune system in both mice and humans, and that it can synergize with Toll-like receptors. Moreover, an antibody agonist of Tim-3 acted as an adjuvant during induced immune responses, and Tim-3 ligation induced distinct signaling events in T cells and dendritic cells; the latter finding could explain the apparent divergent functions of Tim-3 in these cell types. Thus, by virtue of differential expression on innate versus adaptive immune cells, Tim-3 can either promote or terminate TH1 immunity and may be able to influence a range of inflammatory conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Ana C -- Anderson, David E -- Bregoli, Lisa -- Hastings, William D -- Kassam, Nasim -- Lei, Charles -- Chandwaskar, Rucha -- Karman, Jozsef -- Su, Ee W -- Hirashima, Mitsuomi -- Bruce, Jeffrey N -- Kane, Lawrence P -- Kuchroo, Vijay K -- Hafler, David A -- R01 AI067544/AI/NIAID NIH HHS/ -- R01 AI067544-01A2/AI/NIAID NIH HHS/ -- R56 AI067544/AI/NIAID NIH HHS/ -- R56 AI067544-01A1/AI/NIAID NIH HHS/ -- R56 AI067544-02/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1141-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Immunology, Center for Neurologic Diseases, Brigham and Women's Hospital and Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006747" target="_blank"〉PubMed〈/a〉

    Description: We report that developmental competition between sympathetic neurons for survival is critically dependent on a sensitization process initiated by target innervation and mediated by a series of feedback loops. Target-derived nerve growth factor (NGF) promoted expression of its own receptor TrkA in mouse and rat neurons and prolonged TrkA-mediated signals. NGF also controlled expression of brain-derived neurotrophic factor and neurotrophin-4, which, through the receptor p75, can kill neighboring neurons with low retrograde NGF-TrkA signaling whereas neurons with high NGF-TrkA signaling are protected. Perturbation of any of these feedback loops disrupts the dynamics of competition. We suggest that three target-initiated events are essential for rapid and robust competition between neurons: sensitization, paracrine apoptotic signaling, and protection from such effects.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612357/" 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/PMC3612357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deppmann, Christopher D -- Mihalas, Stefan -- Sharma, Nikhil -- Lonze, Bonnie E -- Niebur, Ernst -- Ginty, David D -- EY016281/EY/NEI NIH HHS/ -- F32 NS053187/NS/NINDS NIH HHS/ -- NS053187/NS/NINDS NIH HHS/ -- NS34814/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Apr 18;320(5874):369-73. doi: 10.1126/science.1152677.

    Description: Angiogenesis does not only depend on endothelial cell invasion and proliferation: it also requires pericyte coverage of vascular sprouts for vessel stabilization. These processes are coordinated by vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) through their cognate receptors on endothelial cells and vascular smooth muscle cells (VSMCs), respectively. PDGF induces neovascularization by priming VSMCs/pericytes to release pro-angiogenic mediators. Although VEGF directly stimulates endothelial cell proliferation and migration, its role in pericyte biology is less clear. Here we define a role for VEGF as an inhibitor of neovascularization on the basis of its capacity to disrupt VSMC function. Specifically, under conditions of PDGF-mediated angiogenesis, VEGF ablates pericyte coverage of nascent vascular sprouts, leading to vessel destabilization. At the molecular level, VEGF-mediated activation of VEGF-R2 suppresses PDGF-Rbeta signalling in VSMCs through the assembly of a previously undescribed receptor complex consisting of PDGF-Rbeta and VEGF-R2. Inhibition of VEGF-R2 not only prevents assembly of this receptor complex but also restores angiogenesis in tissues exposed to both VEGF and PDGF. Finally, genetic deletion of tumour cell VEGF disrupts PDGF-Rbeta/VEGF-R2 complex formation and increases tumour vessel maturation. These findings underscore the importance of VSMCs/pericytes in neovascularization and reveal a dichotomous role for VEGF and VEGF-R2 signalling as both a promoter of endothelial cell function and a negative regulator of VSMCs and vessel maturation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605188/" 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/PMC2605188/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenberg, Joshua I -- Shields, David J -- Barillas, Samuel G -- Acevedo, Lisette M -- Murphy, Eric -- Huang, Jianhua -- Scheppke, Lea -- Stockmann, Christian -- Johnson, Randall S -- Angle, Niren -- Cheresh, David A -- GM 68524/GM/NIGMS NIH HHS/ -- P01 CA078045/CA/NCI NIH HHS/ -- P01 CA078045-050004/CA/NCI NIH HHS/ -- P01 CA078045-100004/CA/NCI NIH HHS/ -- P01 CA078045-109001/CA/NCI NIH HHS/ -- R01 CA095262/CA/NCI NIH HHS/ -- R01 CA095262-06/CA/NCI NIH HHS/ -- R01 CA118165/CA/NCI NIH HHS/ -- R01 HL078912/HL/NHLBI NIH HHS/ -- R01 HL078912-04/HL/NHLBI NIH HHS/ -- R21 CA129660/CA/NCI NIH HHS/ -- R21 CA129660-02/CA/NCI NIH HHS/ -- R37 CA050286/CA/NCI NIH HHS/ -- R37 CA050286-19/CA/NCI NIH HHS/ -- R37 CA050286-20/CA/NCI NIH HHS/ -- R37-CA082515/CA/NCI NIH HHS/ -- R37-CA50286/CA/NCI NIH HHS/ -- England -- Nature. 2008 Dec 11;456(7223):809-13. doi: 10.1038/nature07424.

    Description: Diatoms are photosynthetic secondary endosymbionts found throughout marine and freshwater environments, and are believed to be responsible for around one-fifth of the primary productivity on Earth. The genome sequence of the marine centric diatom Thalassiosira pseudonana was recently reported, revealing a wealth of information about diatom biology. Here we report the complete genome sequence of the pennate diatom Phaeodactylum tricornutum and compare it with that of T. pseudonana to clarify evolutionary origins, functional significance and ubiquity of these features throughout diatoms. In spite of the fact that the pennate and centric lineages have only been diverging for 90 million years, their genome structures are dramatically different and a substantial fraction of genes ( approximately 40%) are not shared by these representatives of the two lineages. Analysis of molecular divergence compared with yeasts and metazoans reveals rapid rates of gene diversification in diatoms. Contributing factors include selective gene family expansions, differential losses and gains of genes and introns, and differential mobilization of transposable elements. Most significantly, we document the presence of hundreds of genes from bacteria. More than 300 of these gene transfers are found in both diatoms, attesting to their ancient origins, and many are likely to provide novel possibilities for metabolite management and for perception of environmental signals. These findings go a long way towards explaining the incredible diversity and success of the diatoms in contemporary oceans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowler, Chris -- Allen, Andrew E -- Badger, Jonathan H -- Grimwood, Jane -- Jabbari, Kamel -- Kuo, Alan -- Maheswari, Uma -- Martens, Cindy -- Maumus, Florian -- Otillar, Robert P -- Rayko, Edda -- Salamov, Asaf -- Vandepoele, Klaas -- Beszteri, Bank -- Gruber, Ansgar -- Heijde, Marc -- Katinka, Michael -- Mock, Thomas -- Valentin, Klaus -- Verret, Frederic -- Berges, John A -- Brownlee, Colin -- Cadoret, Jean-Paul -- Chiovitti, Anthony -- Choi, Chang Jae -- Coesel, Sacha -- De Martino, Alessandra -- Detter, J Chris -- Durkin, Colleen -- Falciatore, Angela -- Fournet, Jerome -- Haruta, Miyoshi -- Huysman, Marie J J -- Jenkins, Bethany D -- Jiroutova, Katerina -- Jorgensen, Richard E -- Joubert, Yolaine -- Kaplan, Aaron -- Kroger, Nils -- Kroth, Peter G -- La Roche, Julie -- Lindquist, Erica -- Lommer, Markus -- Martin-Jezequel, Veronique -- Lopez, Pascal J -- Lucas, Susan -- Mangogna, Manuela -- McGinnis, Karen -- Medlin, Linda K -- Montsant, Anton -- Oudot-Le Secq, Marie-Pierre -- Napoli, Carolyn -- Obornik, Miroslav -- Parker, Micaela Schnitzler -- Petit, Jean-Louis -- Porcel, Betina M -- Poulsen, Nicole -- Robison, Matthew -- Rychlewski, Leszek -- Rynearson, Tatiana A -- Schmutz, Jeremy -- Shapiro, Harris -- Siaut, Magali -- Stanley, Michele -- Sussman, Michael R -- Taylor, Alison R -- Vardi, Assaf -- von Dassow, Peter -- Vyverman, Wim -- Willis, Anusuya -- Wyrwicz, Lucjan S -- Rokhsar, Daniel S -- Weissenbach, Jean -- Armbrust, E Virginia -- Green, Beverley R -- Van de Peer, Yves -- Grigoriev, Igor V -- England -- Nature. 2008 Nov 13;456(7219):239-44. doi: 10.1038/nature07410.
