Dynamics of repetitive DNA sequences over the course of evolution and intraspecific divergence of tetraploid goat-grass species Aegilops biuncialis vis
Our study revealed complex genome structure of wild tetraploid grass Ae. biuncialis which might have occurred via multiple hybridization events resulting in formation of three distinct chromosomal groups. Their divergence was accompanied by different chromosomal rearrangements which resulted in formation of highly distinct karyotypes. By using FISH markers, we evaluated the relations between chromosomes of the three groups and developed genetic nomenclature of Ae. biuncialis chromosomes.
