作物驯化是长期的选择实验，极大地促进了人类文明。栽培稻的驯化是历史上最重要的发展之一然而，它的起源和驯化过程是有争议的，长期以来一直争论不休。在这里，我们从446个地理上不同的野生稻物种普通野生稻（栽培稻的直接祖先）和1,083个栽培籼稻和粳稻品种中获得基因组序列，以构建水稻基因组变异的综合图谱。在寻找选择的签名，我们确定了55个选择性扫描驯化过程中发生的。对驯化扫描和全基因组模式的深入分析表明，日本稻是从一个特定的O。中国南方珠江中游地区的野生稻是普通稻的一种，而籼稻则是由粳稻与当地野生稻杂交而成，并作为最初的栽培品种传播到东南亚和南亚。通过高分辨率遗传图谱分析驯化相关性状。本研究为水稻育种提供了重要的资源，也为作物驯化研究提供了有效的基因组学方法。本文的在线版本（doi：10.1038/nature 11532）包含补充材料，可供授权用户使用。野生稻和栽培稻品种的全基因组序列被用来绘制水稻基因组变异图，并表明水稻可能是在中国南方首先驯化的。本文的在线版本（doi：10.1038/nature 11532）包含补充材料，可供授权用户使用。栽培稻（Oryza sativa）被认为是数千年前从野生稻（Oryza rufipogon）驯化而来的。这项中日合作报告了来自亚洲和大洋洲的446个野生稻分离物以及1,000多个栽培稻的籼稻和粳稻亚种的全基因组序列。由此产生的基因组变异图将是水稻育种和作物驯化研究的重要资源。本文的在线版本（doi：10.1038/nature 11532）包含补充材料，可供授权用户使用。
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.

Whole-genome sequences of wild rice and cultivated rice varieties are used to produce a map of rice genome variation, and show that rice was probably first domesticated in southern China. The online version of this article (doi:10.1038/nature11532) contains supplementary material, which is available to authorized users. Cultivated rice (Oryza sativa) is thought to have been domesticated from wild rice (Oryza rufipogon) thousands of years ago. This Chinese/Japanese collaboration reports whole-genome sequences from 446 wild rice isolates from across Asia and Oceana, and from more than 1,000 indica and japonica subspecies of cultivated rice. The resulting map of genome variation will be an important resource for rice breeding and for crop-domestication research.
