Genetic patterns of Hordeum jubatum L. (Poaceae) and × Elyhordeum arcuatum W. W. Mitch. et H. J. Hodgs. in Siberia and Far East of Russia
UDC 575.17:582.52
Abstract
Hordeum jubatum (foxtail barley) is a weed and ornamental plant with a natural range in Eastern Siberia, the Russian Far East and North America. Over the past decades, its range significantly expanded in Eurasia, rapidly spreading westward, while its genetic characteristics remain poorly understood. PCR, molecular cloning, and sequencing of nuclear (ITS) and chloroplast (matK) DNA markers were performed for comparative characteristics of H. jubatum from different parts of its modern range (Western and Eastern Siberia) and for one of the hybridogenic species × Elyhordeum arcuatum. Two variants of the Hordeum H-genome were found in all studied samples. No significant differences in the nucleotide structure of ITS and matK were found in H. jubatum from Western and Eastern Siberia and North America. ITS sequences specific to Elymus sibiricus and H. jubatum prove the participation of these species in the formation of × E. arcuatum, as well as the maternal origin of matK (chloroplast DNA) from H. jubatum. The obtained results complement the genetic characteristics of the studied species and determine further directions of their study.
