Figure 7

Plot of pairwise Fst values among accessions within the three groups of the phylogenetic tree using nuclear DNA data (Fig. 3): East-Honshu, West-Honshu, and Kyushu clades. Details of each Fst value are shown in Supplementary Table S2. The averaged value for each group is indicated by a cross mark. *: no significant difference, **: significantly different at the 5% level (p < 2.20 × 10−16 between East- and West-Honshu; p < 2.20 × 10−9 between East-Honshu and Kyushu).
