Domestication scenario that led to Asian rice. Each domesticated rice subpopulation had separate wild rice progenitor; however, because the geographic origin of the progenitor is heavily debated, its location is omitted from the map. Geographic position of the domesticated rice represents hypothesized domestication areas and was based on Fuller et al. (2010). Red arrow indicates a gene flow event that transferred the japonica originating domestication haplotypes from the genes LABA1, PROG1, and sh4 into the progenitors of aus and indica, which led to their domestication.
