Data from: Domestication and geographic origin of Oryza sativa in China: insights from multilocus analyses of nucleotide variation of O. sativa and O. rufipogon

Previous studies have indicated that China is one of the domestication
centres of Asian cultivated rice (Oryza sativa), and common wild rice (O.
rufipogon) is the progenitor of O. sativa. However, the number of
domestication times and the geographic origin of Asian cultivated rice in
China are still under debate. In this study, 100 accessions of Asian
cultivated rice and 111 accessions of common wild rice in China were
selected to examine the relationship between O. sativa and O. rufipogon
and thereby infer the domestication and evolution of O. sativa in China
through sequence analyses of six gene regions, trnC-ycf6 in chloroplast
genomes, cox3 in mitochondrial genomes and ITS, Ehd1, Waxy, Hd1 in nuclear
genomes. The results indicated that the two subspecies of O. sativa
(indica and japonica) were domesticated independently from different
populations of O. rufipogon with gene flow occurring later from japonica
to indica; Southern China was the genetic diversity centre of O.
rufipogon, and the Pearl River basin near the Tropic of Cancer was the
domestication centre of O. sativa in China.
