A molecular approach to the phylogeny of the moss genus Pseudocrossidium(Pottiaceae,Bryopsida)and its taxonomic implications
文献摘要：
Pseudocrossidium is a genus of 21 species belonging to the Pottiaceae with the highest concentration of taxa and morphological variation found in South America.To investigate the evolutionary relationships among the species of Pseudocrossidium and other members of the Pottioideae,molecular phylogenetic reconstructions,using the nuclear ITS1-5.8S-ITS2,and the plastid atpB-rbcL,trnG,and trnL-F,has been performed because this genus has only been partially tested using molecular markers.Bayesian and maximum likelihood topologies show that the genus,as presently circumscribed,is polyphyletic.Consequently,the circumscription of Pseudocrossidium is amended and numerous taxonomic changes resulting from the molecular,morphological,and nomenclatural studies are proposed.The phylogenetic and morphologically divergent Pseudocrossidium mendozense is renamed as Gertrudiella mendozensis.Pseudocrossidium linearifolium and P.porphyreoneurum are representatives of the new genera Barbulastrum and Helicobarbula,respectively.Pseudocrossidium carinatum and P.santiagense are accommodated in a new genus Austrobarbula.Aloinella,nested in a paraphyletic Pseudocrossidium,is maintained at generic rank,apparently derived from Pseudocrossidium.Barbula integrifolia,B.riograndensis,and Tortula jaffuelii are transferred to Pseudocrossidium.The remaining species of Pseudocrossidium are maintained in this genus,pending further studies.Conflicts of the trees observed could be evidence of interspecific or intergeneric gene flow in various lineages in the Pottioideae.
