图5 第三极荨麻属麻叶荨麻分支物种质体基因组和Angiosperms353核基因数据集的主成分分析(PCA)及遗传分化热图。(A)-(B): 分别基于4种荨麻50个个体的质体基因组和Angiosperms353核基因数据集的PCA分析; (C)-(D): 分别基于4种荨麻50个个体质体基因组和Angiosperms353核基因数据集的遗传分化热图。滇藏荨麻和膜叶荨麻与上述4个物种的系统发育位置较远, 排除在该分析中。UC: 麻叶荨麻; UT: 三角叶荨麻原亚种; UA: 尾尖异株荨麻; UG: 甘肃异株荨麻; UD: 异株荨麻原亚种; UP: 羽裂荨麻; UH: 高原荨麻。FST: 遗传分化指数。

Fig. 5 Principal component analysis (PCA) and genetic differentiation heat map of four Urtica species within cannabina Clade from the Third Pole based on complete plastid genome and Angiosperms353 nuclear gene set. A-B, The result of PCA of plastid genome and concatenated Angiosperms353 nuclear gene set based on 50 individuals of four species, respectively; C-D, The genetic differentiation heat map of plastid genome and concatenated Angiosperms353 nuclear gene set based on 50 individuals of four species, respectively. U. mairei and U. membranifolia are phylogenetically distant from the four species, so they were excluded from this analysis. UC, U. cannabina; UT, U. triangularis subsp. triangularis; UA, U. dioica subsp. afghanica; UG, U. dioica subsp. gansuensis; UD, U. dioica subsp. dioica; UP, U. triangularis subsp. pinnatifida; UH, U. hyperborea. FST: Genetic differentiation index.
