Admixture analysis of the L. cruciata accessions. The number of populations (K) is set to 3 for admixture analysis. The accessions are horizontally aligned according to the three clades (East-Honshu, West-Honshu, and Kyushu) components of the phylogenetic tree using nuclear DNA data (Fig. 3). The colour of each accession indicates the sample collection area; the eastern area of Honshu is red, the western area of Honshu is blue, and Kyushu is green (Fig. 1). The vertical axis indicates the ancestry ratio of the three hypothetical ancestral populations coloured purple, orange, and brown, respectively.
