Zhao K, Wright M, Kimball J, Eizenga G, McClung A, Kovach M, Tyagi W, Ali ML, Tung C-W, Reynolds A, Bustamante CD & McCouch SR 2010 Genomic diversity and introgression in O. sativa reveal the impact of domestication and breeding on the rice genome. PLoS ONE 5:e10780.

• there is clear evidence that gene flow between the subpopulations and even back into the wild rice [19] has resulted in the introgression of genomic segments over the course of the domestication process
