[Cytogenetic comparison of N-genome Aegilops L. species].
Genetika. 2012 May; 48(5):617-27.G

Abstract

Differential C-banding and in situ hybridization were employed in a cytogenetic comparison of thee N-genome Aegilops species: diploid Ae. uniaristata, tetraploid Ae. ventricosa, and hexaploid Ae. recta. The formation of Ae. recta was shown to involve only minor functional modifications of the parental genomes, while intraspecific divergence was accompanied by large genome rearrangements, namely, translocations involving the total chromosome arms of all of the three genomes. The formation of tetraploid Ae. ventricosa involved substantial structural chromosome rearrangements, including a partial deletion of the short arm of chromosome 5D, including the nucleolus-organizing region; a redistribution of C bands on chromosomes of the D and N genomes along with a reduction of the heterochromatin content; and a considerable decrease in the hybridization intensity of the pAs1 repeat. Chromosomes of the Ae. ventricosa D genome were more similar to chromosomes of the Ae. crassa D1 genome than to Ae. tauschii chromosomes.
