Rice phylogenetic trees showing three rice groups. (A) A rice SNP tree constructed by the SNPhylo. The three clusters in the tree reflect the three rice groups. The ellipses in red, blue and green represent japonica, indica and aus group, respectively. The bootstrap values determined with 1,000 samples are represented in red. (B) The tree in the original report for the rice SNPs . The clustered in red, blue and green represents japonica, indica and aus group, respectively as well.
