Fig. 2From: Role of genetic introgression during the evolution of cultivated rice (Oryza sativa L.)PCA of the cultivated O. sativa groups and the identified ancestral gene pools. A total of 5,759,207 genome-wide SNPs were transformed into 700 axes of variation. The first two axes represent 9.7% of the total variation. Rice accessions are coloured according to their domestication classBack to article page
