Molecular phylogeny study of Xamilenis Raf. recognition as the segregate genus in the tribe Sileneae
Background. Xamilenis is oligotypic genus recognised in tribe Sileneae sinse 2001. Conception of the Xamilenis recognition as small segregate genus was examined by molecular phylogeny methods. Materials and methods. We analyzed nuclear (ITS1-5,8S-ITS2) and chloroplast (gene trnL intron) sequences obtained from several species of the genus from different localities and compared with other Sileneae species. Phylogeny trees were constructed via neigbor joining and bayesian approaches. Results. ITS p-distances within Xamilenis genus were similar to those between Xamilenis and Silene species. Xamilenis species did not form monophyletic clade in the ITS tree. They were closely related with Silene species from subgenus Siphonomorpha. Synapomorphicindelsspecific for Xamilenis were not observedin intron trnL. Conclusion. Conception Xamilenis as the segregate genus is not confirmed by molecular phylogeny data.
