Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Changes in plant genomes of hybrid origin which become apparent on different levels of phenotypic manifestation of genetic and epigenetic changes are an important object of cytogenetics and molecular genetics. The changes in expression of the glaucousness trait in the artificial Triticinae amphidiploid Aurotica (AABBTT) were investigated; haplotypes of plants with the appearance of glaucous and non-glaucous genes were determined by hybridization experiments. It was suppoted that the changes in expression can be explained by (epi)mutations abolishing the efficiency of dominant alleles of orthologous series of glaucous inhibitor gene Iw. Analysis of F2 population with SSR markers specific to 2B and 2D wheat chromosomes and 2T chromosome of Aegilops mutica manifested associated inheritance of the Wms 102 and Wms 702 loci, which mapped to the short arm of chromosome 2D. The Wms 702 marker was linked to the Iw2(T) gene and can now be used to detect that gene. |
