Abstract

The structure, at the level of restriction endonuclease mapping, of rDNA spacer regions from representatives of the B, R, S, P, N, J₁J₂, and E genomes within the Triticeae are compared. The results indicate that the evolution of the main spacer region of rDNA units is sufficiently rapid to allow each genome to be clearly identified. The spacer regions can be successfully used to distinguish respective alien rDNA units when they are present in wheat.Key words: Triticeae, alien chromatin, molecular probes, NOR loci.
