Description:
Potato (Solanum tuberosum L.) is the world's most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031 protein-coding genes and present evidence for at least two genome duplication events indicative of a palaeopolyploid origin. As the first genome sequence of an asterid, the potato genome reveals 2,642 genes specific to this large angiosperm clade. We also sequenced a heterozygous diploid clone and show that gene presence/absence variants and other potentially deleterious mutations occur frequently and are a likely cause of inbreeding depression. Gene family expansion, tissue-specific expression and recruitment of genes to new pathways contributed to the evolution of tuber development. The potato genome sequence provides a platform for genetic improvement of this vital crop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Potato Genome Sequencing Consortium -- Xu, Xun -- Pan, Shengkai -- Cheng, Shifeng -- Zhang, Bo -- Mu, Desheng -- Ni, Peixiang -- Zhang, Gengyun -- Yang, Shuang -- Li, Ruiqiang -- Wang, Jun -- Orjeda, Gisella -- Guzman, Frank -- Torres, Michael -- Lozano, Roberto -- Ponce, Olga -- Martinez, Diana -- De la Cruz, German -- Chakrabarti, S K -- Patil, Virupaksh U -- Skryabin, Konstantin G -- Kuznetsov, Boris B -- Ravin, Nikolai V -- Kolganova, Tatjana V -- Beletsky, Alexey V -- Mardanov, Andrei V -- Di Genova, Alex -- Bolser, Daniel M -- Martin, David M A -- Li, Guangcun -- Yang, Yu -- Kuang, Hanhui -- Hu, Qun -- Xiong, Xingyao -- Bishop, Gerard J -- Sagredo, Boris -- Mejia, Nilo -- Zagorski, Wlodzimierz -- Gromadka, Robert -- Gawor, Jan -- Szczesny, Pawel -- Huang, Sanwen -- Zhang, Zhonghua -- Liang, Chunbo -- He, Jun -- Li, Ying -- He, Ying -- Xu, Jianfei -- Zhang, Youjun -- Xie, Binyan -- Du, Yongchen -- Qu, Dongyu -- Bonierbale, Merideth -- Ghislain, Marc -- Herrera, Maria del Rosario -- Giuliano, Giovanni -- Pietrella, Marco -- Perrotta, Gaetano -- Facella, Paolo -- O'Brien, Kimberly -- Feingold, Sergio E -- Barreiro, Leandro E -- Massa, Gabriela A -- Diambra, Luis -- Whitty, Brett R -- Vaillancourt, Brieanne -- Lin, Haining -- Massa, Alicia N -- Geoffroy, Michael -- Lundback, Steven -- DellaPenna, Dean -- Buell, C Robin -- Sharma, Sanjeev Kumar -- Marshall, David F -- Waugh, Robbie -- Bryan, Glenn J -- Destefanis, Marialaura -- Nagy, Istvan -- Milbourne, Dan -- Thomson, Susan J -- Fiers, Mark -- Jacobs, Jeanne M E -- Nielsen, Kare L -- Sonderkaer, Mads -- Iovene, Marina -- Torres, Giovana A -- Jiang, Jiming -- Veilleux, Richard E -- Bachem, Christian W B -- de Boer, Jan -- Borm, Theo -- Kloosterman, Bjorn -- van Eck, Herman -- Datema, Erwin -- Hekkert, Bas te Lintel -- Goverse, Aska -- van Ham, Roeland C H J -- Visser, Richard G F -- BB/F012640/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F012640/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT 083481/Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 10;475(7355):189-95. doi: 10.1038/nature10158.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Chinese Ministry of Agricultural, Key Lab of Genomics, Beishan Industrial Zone, Yantian District, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21743474" target="_blank"〉PubMed〈/a〉
