摘要
目的：研究石杉科17种植物的系统发育关系和石杉科植物条形码。方法：使用叶绿体trnH-psbA基因序列构建了石杉科的系统发育树。结果：表明石杉科植物高度聚类为两个分支,自展支持率达91%。结论：支持Hol-ub和秦仁昌将石杉科分为石杉属和马尾杉属的分类学观点。17种石杉科植物种具有良好的单系性,trnH-psbA基因能在种水平很好区分石杉科植物,可以作为本科分类鉴定条形码。
Objective：The purpose of study was to discover the phylogenetic relations and plant barcoding of 17 plants from Huperziaceae.Methods：Phylogenetic tree of chloroplast trnH-psbA gene of 17 plants from Huperziaceae was constructed by software.Results：It showed that Huperziaceae could be divided into two genera Huperzia and Phlegmariurus and bootstrap value reached 91%.Conclusions：Holub and Qing′ taxonomy was supported and 17 species in Huperziaceae were monophyletic groups and it suggested that trnH-psbA could be used as a DNA barcode to identify plants.
