The domestication scenario that led to Asian rice () is a contentious topic. Here, we have reanalyzed a previously published large-scale wild and domesticated rice data set, which was also analyzed by two studies but resulted in two contrasting domestication models. We suggest that the analysis of false-positive selective sweep regions and phylogenetic analysis of concatenated genomic regions may have been the sources that contributed to the different results. In the end, our result indicates that Asian rice originated from multiple wild progenitor subpopulations; however, domestication appears to have occurred only once and the domestication alleles were transferred between rice subpopulations through introgression.
导致亚洲栽培稻（）的驯化过程是一个有争议的话题。在此，我们重新分析了一个先前发表的大规模野生和驯化稻数据集，另外两项研究也分析过该数据集，但得出了两种截然不同的驯化模型。我们认为，假阳性选择清除区域的分析以及串联基因组区域的系统发育分析可能是导致不同结果的原因。最终，我们的结果表明，亚洲栽培稻起源于多个野生祖先亚群；然而，驯化似乎只发生过一次，驯化等位基因通过渐渗在水稻亚群之间转移。
