Abstract
Elymus L. is a genus of the Poaceae family which includes allopolyploid species only. Taxa of the genus are widespread over all continents, at least half of them have been occured in Asia, and this continent is considered to be its motherland. However, the diversity, genetic characteristics, and evolutionary interactions among Elymus species of some regions of Asia are still vague, and the Asian part of Russia is one of such territories. Thus, investigation of evolutionary relations among species of Siberia, Far East and Kamchatka is promising. In this work, several sequences of two nuclear genes and rDNA Internal Transcribed Spacers annotated in databases are analyzed. Nuclear genes sequences are shown to be more useful in building phylogeny at the interspecies level. Also, a region of the nuclear gene waxy is shown to vary among different haplomes. This variation makes it useful in investigating the genome constitutions of novel Elymus species. Finally, systematical status of E. kamczadalorum (Nevski) Tzvel. was proven valid as a species.
