《Nature》2012.10.25-水稻全基因组遗传变异图谱揭示栽培稻的起源 2012/12/05 | 归类于: 《自然》- Nature | 作者: 生物分子 PDF版本 中国科学院上海生命科学院、植物生理生态研究所、国家基因研究中心的科学家们最新研究表明，人类种植的第一个水稻株系是粳稻，该人类种植数千年之久的粳稻发源于中国华南地区的珠江流域，它来自于珠江的一种野生稻。 -2012年10月25日《自然》 中文翻译 【题目】 水稻全基因组遗传变异图谱揭示栽培稻的起源 【译文】 作物驯化是长期选择性的实验，大大促进了人类文明的发展。栽培稻的驯化被认为是作物驯化历史上最重要的发展之一。然而，它的起源和驯化过程存在矛盾，而且长期以来一直存在争论。本研究建立了来自446个不同地域的野生水稻物种野生稻（栽培稻的直接祖先）以及来自1083个种植籼稻和粳稻品种的全基因组序列，以构建水稻基因组差异的综合图谱。在探索筛选标志中，我们鉴定了发生在驯化过程期间的55个选择性清除。驯化范围和基因组范围模式的深度分析揭示粳稻是第一个在华南珠江流域中部从野生稻的特殊群体中被驯化出来的品种，而亚洲籼稻是随后由粳稻和当地野生稻之间发展成为遍布东亚和南亚的品种。我们利用高分辨率的遗传图谱分析了驯化相关特性。本研究为水稻培育提供了重要资源，并为作物驯化研究提供了有效的基因组学方法。 英文原稿 : A map of rice genome variation reveals the origin of cultivated rice : Xuehui Huang, Nori Kurata, Xinghua Wei, Zi-Xuan Wang, Ahong Wang, Qiang Zhao, Yan Zhao, Kunyan Liu, Hengyun Lu, Wenjun Li, Yunli Guo, Yiqi Lu, Congcong Zhou, Danlin Fan, Qijun Weng,1 Chuanrang Zhu,1 Tao Huang,1 Lei Zhang,1 Yongchun Wang,1 Lei Feng,1 Hiroyasu Furuumi,2 Takahiko Kubo,2 Toshie Miyabayashi,2 Xiaoping Yuan,3 Qun Xu,3 Guojun Dong,3 Qilin Zhan,1 Canyang Li,1 Asao Fujiyama,2 Atsushi Toyoda,2 Tingting Lu,1 Qi Feng,1 Qian Qian,3 Jiayang Li4 Bin Han1, 5 et al. ： Crop domestications are long-term selection experiments that have greatly advanced human civilization. The domestication of cultivated rice (Oryza sativa L.) ranks as one of the most important developments in history. However, its origins and domestication processes are controversial and have long been debated. Here we generate genome sequences from 446 geographically diverse accessions of the wild rice species Oryza rufipogon, the immediate ancestral progenitor of cultivated rice, and from 1,083 cultivated indica and japonica varieties to construct a comprehensive map of rice genome variation. In the search for signatures of selection, we identify 55 selective sweeps that have occurred during domestication. In-depth analyses of the domestication sweeps and genome-wide patterns reveal that Oryza sativa japonica rice was first domesticated from a specific population of O. rufipogon around the middle area of the Pearl River in southern China, and that Oryza sativa indica rice was subsequently developed from crosses between japonica rice and local wild rice as the initial cultivars spread into South East and South Asia. The domestication-associated traits are analysed through high-resolution genetic mapping. This study provides an important resource for rice breeding and an effective genomics approach for crop domestication research. 原文地址 http://www.nature.com/nature/journal/v490/n7421/full/nature11532.html 标签： NATURE , nature-2012-10-25 , 图谱 , 水稻基因组差异 , 起源 , 驯化
