Multiple origin but single domestication led to Oryza sativa

Abstract

The domestication scenario that led to Asian rice (Oryza sativa) 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, de novo domestication appears to have occurred only once and the domestication alleles were transferred between rice subpopulations through introgression.
