    Genetic Architecture of Variation in the Lateral Line Sensory System of Threespine Sticklebacks (2012)
    Genetics Society of America (GSA)
    Details
    Publication Date: 2012-09-06
    Description: Vertebrate sensory systems have evolved remarkable diversity, but little is known about the underlying genetic mechanisms. The lateral line sensory system of aquatic vertebrates is a promising model for genetic investigations of sensory evolution because there is extensive variation within and between species, and this variation is easily quantified. In the present study, we compare the lateral line sensory system of threespine sticklebacks ( Gasterosteus aculeatus ) from an ancestral marine and a derived benthic lake population. We show that lab-raised individuals from these populations display differences in sensory neuromast number, neuromast patterning, and groove morphology. Using genetic linkage mapping, we identify regions of the genome that influence different aspects of lateral line morphology. Distinct loci independently affect neuromast number on different body regions, suggesting that a modular genetic structure underlies the evolution of peripheral receptor number in this sensory system. Pleiotropy and/or tight linkage are also important, as we identify a region on linkage group 21 that affects multiple aspects of lateral line morphology. Finally, we detect epistasis between a locus on linkage group 4 and a locus on linkage group 21; interactions between these loci contribute to variation in neuromast pattern. Our results reveal a complex genetic architecture underlying the evolution of the stickleback lateral line sensory system. This study further uncovers a genetic relationship between sensory morphology and non-neural traits (bony lateral plates), creating an opportunity to investigate morphological constraints on sensory evolution in a vertebrate model system.

    Complete Plastome Sequences from Glycine syndetika and Six Additional Perennial Wild Relatives of Soybean (2014)
    Genetics Society of America (GSA)
    Details
    Publication Date: 2014-10-17
    Description: Organelle sequences have a long history of utility in phylogenetic analyses. Chloroplast sequences when combined with nuclear data can help resolve relationships among flowering plant genera, and within genera incongruence can point to reticulate evolution. Plastome sequences are becoming plentiful because they are increasingly easier to obtain. Complete plastome sequences allow us to detect rare rearrangements and test the tempo of sequence evolution. Chloroplast sequences are generally considered a nuisance to be kept to a minimum in bacterial artificial chromosome libraries. Here, we sequenced two bacterial artificial chromosomes per species to generate complete plastome sequences from seven species. The plastome sequences from Glycine syndetika and six other perennial Glycine species are similar in arrangement and gene content to the previously published soybean plastome. Repetitive sequences were detected in high frequencies as in soybean, but further analysis showed that repeat sequence numbers are inflated. Previous chloroplast-based phylogenetic trees for perennial Glycine were incongruent with nuclear gene–based phylogenetic trees. We tested whether the hypothesis of introgression was supported by the complete plastomes. Alignment of complete plastome sequences and Bayesian analysis allowed us to date putative hybridization events supporting the hypothesis of introgression and chloroplast "capture."

    Genome sequence of the palaeopolyploid soybean (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-01-16
    Description: Soybean (Glycine max) is one of the most important crop plants for seed protein and oil content, and for its capacity to fix atmospheric nitrogen through symbioses with soil-borne microorganisms. We sequenced the 1.1-gigabase genome by a whole-genome shotgun approach and integrated it with physical and high-density genetic maps to create a chromosome-scale draft sequence assembly. We predict 46,430 protein-coding genes, 70% more than Arabidopsis and similar to the poplar genome which, like soybean, is an ancient polyploid (palaeopolyploid). About 78% of the predicted genes occur in chromosome ends, which comprise less than one-half of the genome but account for nearly all of the genetic recombination. Genome duplications occurred at approximately 59 and 13 million years ago, resulting in a highly duplicated genome with nearly 75% of the genes present in multiple copies. The two duplication events were followed by gene diversification and loss, and numerous chromosome rearrangements. An accurate soybean genome sequence will facilitate the identification of the genetic basis of many soybean traits, and accelerate the creation of improved soybean varieties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmutz, Jeremy -- Cannon, Steven B -- Schlueter, Jessica -- Ma, Jianxin -- Mitros, Therese -- Nelson, William -- Hyten, David L -- Song, Qijian -- Thelen, Jay J -- Cheng, Jianlin -- Xu, Dong -- Hellsten, Uffe -- May, Gregory D -- Yu, Yeisoo -- Sakurai, Tetsuya -- Umezawa, Taishi -- Bhattacharyya, Madan K -- Sandhu, Devinder -- Valliyodan, Babu -- Lindquist, Erika -- Peto, Myron -- Grant, David -- Shu, Shengqiang -- Goodstein, David -- Barry, Kerrie -- Futrell-Griggs, Montona -- Abernathy, Brian -- Du, Jianchang -- Tian, Zhixi -- Zhu, Liucun -- Gill, Navdeep -- Joshi, Trupti -- Libault, Marc -- Sethuraman, Anand -- Zhang, Xue-Cheng -- Shinozaki, Kazuo -- Nguyen, Henry T -- Wing, Rod A -- Cregan, Perry -- Specht, James -- Grimwood, Jane -- Rokhsar, Dan -- Stacey, Gary -- Shoemaker, Randy C -- Jackson, Scott A -- England -- Nature. 2010 Jan 14;463(7278):178-83. doi: 10.1038/nature08670.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉HudsonAlpha Genome Sequencing Center, 601 Genome Way, Huntsville, Alabama 35806, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075913" target="_blank"〉PubMed〈/a〉

    The amphioxus genome and the evolution of the chordate karyotype (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-06-20
    Description: Lancelets ('amphioxus') are the modern survivors of an ancient chordate lineage, with a fossil record dating back to the Cambrian period. Here we describe the structure and gene content of the highly polymorphic approximately 520-megabase genome of the Florida lancelet Branchiostoma floridae, and analyse it in the context of chordate evolution. Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization, as well as a description of two genome-wide duplications and subsequent reorganizations in the vertebrate lineage. These genome-scale events shaped the vertebrate genome and provided additional genetic variation for exploitation during vertebrate evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Butts, Thomas -- Ferrier, David E K -- Furlong, Rebecca F -- Hellsten, Uffe -- Kawashima, Takeshi -- Robinson-Rechavi, Marc -- Shoguchi, Eiichi -- Terry, Astrid -- Yu, Jr-Kai -- Benito-Gutierrez, E Lia -- Dubchak, Inna -- Garcia-Fernandez, Jordi -- Gibson-Brown, Jeremy J -- Grigoriev, Igor V -- Horton, Amy C -- de Jong, Pieter J -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kohara, Yuji -- Kuroki, Yoko -- Lindquist, Erika -- Lucas, Susan -- Osoegawa, Kazutoyo -- Pennacchio, Len A -- Salamov, Asaf A -- Satou, Yutaka -- Sauka-Spengler, Tatjana -- Schmutz, Jeremy -- Shin-I, Tadasu -- Toyoda, Atsushi -- Bronner-Fraser, Marianne -- Fujiyama, Asao -- Holland, Linda Z -- Holland, Peter W H -- Satoh, Nori -- Rokhsar, Daniel S -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Jun 19;453(7198):1064-71. doi: 10.1038/nature06967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18563158" target="_blank"〉PubMed〈/a〉

    The Trichoplax genome and the nature of placozoans (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-08-23
    Description: As arguably the simplest free-living animals, placozoans may represent a primitive metazoan form, yet their biology is poorly understood. Here we report the sequencing and analysis of the approximately 98 million base pair nuclear genome of the placozoan Trichoplax adhaerens. Whole-genome phylogenetic analysis suggests that placozoans belong to a 'eumetazoan' clade that includes cnidarians and bilaterians, with sponges as the earliest diverging animals. The compact genome shows conserved gene content, gene structure and synteny in relation to the human and other complex eumetazoan genomes. Despite the apparent cellular and organismal simplicity of Trichoplax, its genome encodes a rich array of transcription factor and signalling pathway genes that are typically associated with diverse cell types and developmental processes in eumetazoans, motivating further searches for cryptic cellular complexity and/or as yet unobserved life history stages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srivastava, Mansi -- Begovic, Emina -- Chapman, Jarrod -- Putnam, Nicholas H -- Hellsten, Uffe -- Kawashima, Takeshi -- Kuo, Alan -- Mitros, Therese -- Salamov, Asaf -- Carpenter, Meredith L -- Signorovitch, Ana Y -- Moreno, Maria A -- Kamm, Kai -- Grimwood, Jane -- Schmutz, Jeremy -- Shapiro, Harris -- Grigoriev, Igor V -- Buss, Leo W -- Schierwater, Bernd -- Dellaporta, Stephen L -- Rokhsar, Daniel S -- England -- Nature. 2008 Aug 21;454(7207):955-60. doi: 10.1038/nature07191.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrative Genomics and Department of Molecular and Cell Biology, University of California, Berkeley, California 94720, USA. msrivast@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719581" target="_blank"〉PubMed〈/a〉

    The genome of Laccaria bicolor provides insights into mycorrhizal symbiosis (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-07
    Description: Mycorrhizal symbioses--the union of roots and soil fungi--are universal in terrestrial ecosystems and may have been fundamental to land colonization by plants. Boreal, temperate and montane forests all depend on ectomycorrhizae. Identification of the primary factors that regulate symbiotic development and metabolic activity will therefore open the door to understanding the role of ectomycorrhizae in plant development and physiology, allowing the full ecological significance of this symbiosis to be explored. Here we report the genome sequence of the ectomycorrhizal basidiomycete Laccaria bicolor (Fig. 1) and highlight gene sets involved in rhizosphere colonization and symbiosis. This 65-megabase genome assembly contains approximately 20,000 predicted protein-encoding genes and a very large number of transposons and repeated sequences. We detected unexpected genomic features, most notably a battery of effector-type small secreted proteins (SSPs) with unknown function, several of which are only expressed in symbiotic tissues. The most highly expressed SSP accumulates in the proliferating hyphae colonizing the host root. The ectomycorrhizae-specific SSPs probably have a decisive role in the establishment of the symbiosis. The unexpected observation that the genome of L. bicolor lacks carbohydrate-active enzymes involved in degradation of plant cell walls, but maintains the ability to degrade non-plant cell wall polysaccharides, reveals the dual saprotrophic and biotrophic lifestyle of the mycorrhizal fungus that enables it to grow within both soil and living plant roots. The predicted gene inventory of the L. bicolor genome, therefore, points to previously unknown mechanisms of symbiosis operating in biotrophic mycorrhizal fungi. The availability of this genome provides an unparalleled opportunity to develop a deeper understanding of the processes by which symbionts interact with plants within their ecosystem to perform vital functions in the carbon and nitrogen cycles that are fundamental to sustainable plant productivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, F -- Aerts, A -- Ahren, D -- Brun, A -- Danchin, E G J -- Duchaussoy, F -- Gibon, J -- Kohler, A -- Lindquist, E -- Pereda, V -- Salamov, A -- Shapiro, H J -- Wuyts, J -- Blaudez, D -- Buee, M -- Brokstein, P -- Canback, B -- Cohen, D -- Courty, P E -- Coutinho, P M -- Delaruelle, C -- Detter, J C -- Deveau, A -- DiFazio, S -- Duplessis, S -- Fraissinet-Tachet, L -- Lucic, E -- Frey-Klett, P -- Fourrey, C -- Feussner, I -- Gay, G -- Grimwood, J -- Hoegger, P J -- Jain, P -- Kilaru, S -- Labbe, J -- Lin, Y C -- Legue, V -- Le Tacon, F -- Marmeisse, R -- Melayah, D -- Montanini, B -- Muratet, M -- Nehls, U -- Niculita-Hirzel, H -- Oudot-Le Secq, M P -- Peter, M -- Quesneville, H -- Rajashekar, B -- Reich, M -- Rouhier, N -- Schmutz, J -- Yin, T -- Chalot, M -- Henrissat, B -- Kues, U -- Lucas, S -- Van de Peer, Y -- Podila, G K -- Polle, A -- Pukkila, P J -- Richardson, P M -- Rouze, P -- Sanders, I R -- Stajich, J E -- Tunlid, A -- Tuskan, G -- Grigoriev, I V -- England -- Nature. 2008 Mar 6;452(7183):88-92. doi: 10.1038/nature06556.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UMR 1136, INRA-Nancy Universite, Interactions Arbres/Microorganismes, INRA-Nancy, 54280 Champenoux, France. fmartin@nancy.inra.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18322534" target="_blank"〉PubMed〈/a〉

    The Phaeodactylum genome reveals the evolutionary history of diatom genomes (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-10-17
    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.

    A role for a neo-sex chromosome in stickleback speciation (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-29
    Description: Sexual antagonism, or conflict between the sexes, has been proposed as a driving force in both sex-chromosome turnover and speciation. Although closely related species often have different sex-chromosome systems, it is unknown whether sex-chromosome turnover contributes to the evolution of reproductive isolation between species. Here we show that a newly evolved sex chromosome contains genes that contribute to speciation in threespine stickleback fish (Gasterosteus aculeatus). We first identified a neo-sex chromosome system found only in one member of a sympatric species pair in Japan. We then performed genetic linkage mapping of male-specific traits important for reproductive isolation between the Japanese species pair. The neo-X chromosome contains loci for male courtship display traits that contribute to behavioural isolation, whereas the ancestral X chromosome contains loci for both behavioural isolation and hybrid male sterility. Our work not only provides strong evidence for a large X-effect on reproductive isolation in a vertebrate system, but also provides direct evidence that a young neo-X chromosome contributes to reproductive isolation between closely related species. Our data indicate that sex-chromosome turnover might have a greater role in speciation than was previously appreciated.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2776091/" 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/PMC2776091/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kitano, Jun -- Ross, Joseph A -- Mori, Seiichi -- Kume, Manabu -- Jones, Felicity C -- Chan, Yingguang F -- Absher, Devin M -- Grimwood, Jane -- Schmutz, Jeremy -- Myers, Richard M -- Kingsley, David M -- Peichel, Catherine L -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50 HG002568-08/HG/NHGRI NIH HHS/ -- P50 HG02568/HG/NHGRI NIH HHS/ -- R01 GM071854/GM/NIGMS NIH HHS/ -- R01 GM071854-05/GM/NIGMS NIH HHS/ -- T32 GM07270/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Oct 22;461(7267):1079-83. doi: 10.1038/nature08441.

    The Sorghum bicolor genome and the diversification of grasses (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-02-04
    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〉
