图4 基于质体基因组和Angiosperms353核基因数据集的麻叶荨麻分支的系统发育关系和遗传结构。系统发育树节点处黑色圆点表示自展值大于90%, 灰色圆点表示自展值为70%-90%; 不同的背景颜色对应不同的物种。(A)基于最大似然法推断的质体的系统发育树; (B)基于质体基因组数据的4种荨麻属植物的Structure分析结果(最佳K = 5); (C)基于最大似然法推断的Angiosperms353核基因数据集的系统发育树; (D)基于Angiosperms353核基因数据集的4种荨麻属植物的Structure分析结果(最佳K = 3)。U. cannabina: 麻叶荨麻; U. triangularis subsp. triangularis: 三角叶荨麻原亚种; U. dioica subsp. afghanica: 尾尖异株荨麻; U. dioica subsp. gansuensis: 甘肃异株荨麻; U. dioica subsp. dioica: 异株荨麻原亚种; U. triangularis subsp. pinnatifida: 羽裂荨麻; U. hyperborea: 高原荨麻; Outgroups: 外类群。

Fig. 4 Phylogenetic relationships and genetic structure based on complete plastid genome and Angiosperms353 nuclear gene set. Black dots represent the bootstrap > 90%, gray dots represent the bootstrap 70%-90%; the different species are highlighted with different colored backgrounds. (A) Phylogenetic tree of complete plastid genome based on the maximum likelihood (ML) methods; (B) Structure analysis result of complete plastid genome for four species (optimal K = 5); (C) Phylogenetic tree of Angiosperms353 nuclear gene set based on the ML methods. (D) Structure analysis result of Angiosperms353 nuclear gene set for four species (optimal K = 3).
