Extended Data Fig. 7: Population genetic structure of Corydalis hemidicentra.

a, Maximum-likelihood phylogenies of the six populations of C. hemidicentra and the outgroup (Corydalis calcicola). Caishichang (CSC), Huaguangfeng (HGF), Pujinlangba (PJ) come from the Northwest lineage, and Dongbaxueshan (DB), Tianbaoshan (TBS), Shikaxueshan (SK) belong to the Southeast lineage. b, The ML tree inferred from the chloroplast genome sequence. Sample numbers in green font represent green-leaved individuals, those in grey font camouflaged individuals. c, Distribution of cross validation error in the ADMIXTURE analyses, each K conducted 10 independent runs. The box represents the 25th and 75th percentiles, with the middle line indicating the median, while the whiskers extend up to 1.5 times the interquartile range. d, ADMIXTURE results based on whole-genome SNPs with K = 2 to 6. e, Principal component analysis of PC1 and PC2.
