摘要:
 金线草的系统位置一直存在争议,该试验以Triplaris weigeltiana为外类群,采用最大简约法对金线草及其近缘类群的ITS序列进行了系统发育分析。结果表明:(1)金线草和蓼属的春蓼组、刺蓼组形成三个并列的分支,因此,金线草没有必要独立成属,分子证据支持金线草成立为组;(2)金线草和春蓼组、刺蓼组植物聚在一起,自展支持率为96%,说明它们之间有很近的亲缘关系。
Abstract:
 Phylogenetic origin of Antenoron filiforme remains unknown. Phylogenetic analyses were conducted on sequences of nuclear ITS sequences for species of A.filiforme and allies. Triplaris weigeltiana was designed as outgroup. The analyses were performed using parsimony reconstruction methods. Some conclusions could be drawn as follows:(1)A.filiforme and sect.Persicaria,sect.Echinocaulon formed three paratactic clades. Therefore,it was unnecessary to accord A.filiforme as genus rank and it was appropriate to accord A.filiforme as section rank.(2)A.filiforme clustered with sect.Persicaria,sect.Echinocaulon with a bootstrap value of 96%,indicating their close affinity.
