Description:
Papaya, a fruit crop cultivated in tropical and subtropical regions, is known for its nutritional benefits and medicinal applications. Here we report a 3x draft genome sequence of 'SunUp' papaya, the first commercial virus-resistant transgenic fruit tree to be sequenced. The papaya genome is three times the size of the Arabidopsis genome, but contains fewer genes, including significantly fewer disease-resistance gene analogues. Comparison of the five sequenced genomes suggests a minimal angiosperm gene set of 13,311. A lack of recent genome duplication, atypical of other angiosperm genomes sequenced so far, may account for the smaller papaya gene number in most functional groups. Nonetheless, striking amplifications in gene number within particular functional groups suggest roles in the evolution of tree-like habit, deposition and remobilization of starch reserves, attraction of seed dispersal agents, and adaptation to tropical daylengths. Transgenesis at three locations is closely associated with chloroplast insertions into the nuclear genome, and with topoisomerase I recognition sites. Papaya offers numerous advantages as a system for fruit-tree functional genomics, and this draft genome sequence provides the foundation for revealing the basis of Carica's distinguishing morpho-physiological, medicinal and nutritional properties.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2836516/" 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/PMC2836516/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ming, Ray -- Hou, Shaobin -- Feng, Yun -- Yu, Qingyi -- Dionne-Laporte, Alexandre -- Saw, Jimmy H -- Senin, Pavel -- Wang, Wei -- Ly, Benjamin V -- Lewis, Kanako L T -- Salzberg, Steven L -- Feng, Lu -- Jones, Meghan R -- Skelton, Rachel L -- Murray, Jan E -- Chen, Cuixia -- Qian, Wubin -- Shen, Junguo -- Du, Peng -- Eustice, Moriah -- Tong, Eric -- Tang, Haibao -- Lyons, Eric -- Paull, Robert E -- Michael, Todd P -- Wall, Kerr -- Rice, Danny W -- Albert, Henrik -- Wang, Ming-Li -- Zhu, Yun J -- Schatz, Michael -- Nagarajan, Niranjan -- Acob, Ricelle A -- Guan, Peizhu -- Blas, Andrea -- Wai, Ching Man -- Ackerman, Christine M -- Ren, Yan -- Liu, Chao -- Wang, Jianmei -- Wang, Jianping -- Na, Jong-Kuk -- Shakirov, Eugene V -- Haas, Brian -- Thimmapuram, Jyothi -- Nelson, David -- Wang, Xiyin -- Bowers, John E -- Gschwend, Andrea R -- Delcher, Arthur L -- Singh, Ratnesh -- Suzuki, Jon Y -- Tripathi, Savarni -- Neupane, Kabi -- Wei, Hairong -- Irikura, Beth -- Paidi, Maya -- Jiang, Ning -- Zhang, Wenli -- Presting, Gernot -- Windsor, Aaron -- Navajas-Perez, Rafael -- Torres, Manuel J -- Feltus, F Alex -- Porter, Brad -- Li, Yingjun -- Burroughs, A Max -- Luo, Ming-Cheng -- Liu, Lei -- Christopher, David A -- Mount, Stephen M -- Moore, Paul H -- Sugimura, Tak -- Jiang, Jiming -- Schuler, Mary A -- Friedman, Vikki -- Mitchell-Olds, Thomas -- Shippen, Dorothy E -- dePamphilis, Claude W -- Palmer, Jeffrey D -- Freeling, Michael -- Paterson, Andrew H -- Gonsalves, Dennis -- Wang, Lei -- Alam, Maqsudul -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 GM083873-05/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- England -- Nature. 2008 Apr 24;452(7190):991-6. doi: 10.1038/nature06856.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Hawaii Agriculture Research Center, Aiea, Hawaii 96701, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18432245" target="_blank"〉PubMed〈/a〉
