| 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,... |

| 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. |
| Keywords: | Antenoron filiforme ITS sect Persicaria |
