| 摘 要： | 为研究紫茎泽兰(Eupatorium adenophorum Spreng)在菊科的系统发育,利用通用引物对紫茎泽兰叶绿体DNA的rpl16内含子及psbA-trnH与trnL-F两个基因间隔区进行PCR扩增并测序,将其序列分别与GenBank中部分菊科(Asteraceae)植物的基因序列进行比对分析。应用Mega 4.0软件进行分子遗传进化分析,采用邻接法构建系统进化树。结果表明,菊科植物在系统分类上呈现出两大类群,滨菊、野菊构成一个大类,和紫茎泽兰关系较远;紫茎泽兰和毛叶泽兰、圆叶泽兰、线叶泽兰等泽兰属植物及油菊的关系最近,与向日葵和银胶菊次之,与莴苣、滨菊、野菊关系最远,表明紫茎泽兰确实隶属于泽兰属;序列组合(rpl16+ps-bA-trnH+trnL-F)长度变异范围为2 140~2 203 bp,排序后的比对长度为2 399 bp,有381个变异位点,190个信息位点,为紫茎泽兰的系统进化提供了一定的信息。

| Abstract: | In order to analyze the taxonomic status of Eupatorium adenophorum Spreng in Asteracea,the chloroplast rpl16,psbA-trnH and trnL-F of Eupatorium adenophorum Spreng were amplified and sequenced.All the sequences were analyzed basing on sequence alignment with other chloroplast genes of Asteracea species in GenBank.Phylogenetic analysis was conducted with Mega 4.0 software.Phylogenetic relationships were estimated by neighbor-joining method.The results indicated that,The Composite plants can be classified as t... |
