Phylogenetic analysis of Kengyilia species based on nuclear ribosomal DNA internal transcribed spacer sequences
Year: 2008
Type: article
Abstract: Phylogenetic analysis was conducted based on sequences of the internal transcribed spacer region (ITS) of nuclear ribosomal DNA in 17 species of Kengyilia, together with those of 18 species from Pseudoroegneria, Agropyron, Roegneria and Douglasdeweya by the maximum parsimony, maximum likelihood and neighbor-joining distance methods. The results indicate that species of Kengyilia had close affinities to species of Douglasdeweya and Agropyron. The species in Kengyilia was identified as two subgroups with regard to geographic distribution, indicating that species from the same distribution had a closer phylogenetic relationship. The genus Kengyilia was found as a ligament-group between Roegneria and Agropyron. The ITS sequence is a useful tool for studying the phylogeny of closely related species.
