The hDNA content and number of histone genes in the genomes of different wheat and Aegilops species have been determined by molecular hybridization of DNA with /sup 125/I-histone DNA of Drosophila (L-repeat) on nitrocellulose filters. It has been demonstrated that the proportion of hDNA in the total DNA of diploid and polyploid wheat species is (1.3-7.7) x 10/sup -3/% (57-850 genes), and in the ploidy series of Aegilops species (2.0-8.0) x 10/sup -3/% (89-780 genes). The repeatability of the histone genes generally increases at each ploidy level in the species with higher DNA content. At the same time, it has been demonstrated that the DNA content is not the only factor determining repeatability of the histone genes, as some diploid and allopolyploid species have similar number of these genes. It has been concluded that genetic mechanisms are involved in the regulation of the number of histone genes.
