[The genomic organization and localization on the chromosomes of the HvRT family of DNA repetitive sequences in barley].
HvRT family of repetitive DNA sequences from barley genome appears to have complex hierarchical organization. Tandem repetition of 118-bp monomers constitutes lower level of HvRT-family organization. Amplification units of the higher level consist of several contiguous 118-bp monomers. RFLP between different species and cultivars of barley resulted from the differences in the higher-order repeat structure. Individual chromosomes of barley contain specific HvRT subfamilies. This family also possesses separate domains differing in the restriction enzyme sites density. HvRT family is presented in the genomes of H. vulgare, H. leporinum, H. murinum, H. jubatum, but is absent in the genomes of H. marinum, H. geniculatum and wheat.
