Meiotic chromosome pairing is one of the most fundamental biological processes. It provides not only for a regular disjunction of homologous chromosomes in anaphase I of meiosis, thus assuring production of gametes with balanced chromosome numbers, but also allows for recombination leading to the exchange of genetic information between the parental genomes and chromosomes. I am interested in the mechanisms responsible for chromosome pairing and recombination. Manipulation of at least some parameters of genetic recombination in agronomically important crops would allow the production of novel gene combination, or more efficient methods of producing desirable gene combinations. By creating special chromosome constructs and using genes affecting bread making properties of wheat as markers, we are trying to manipulate the distribution, frequency and stringency of crossing over. By manipulating the genetic system responsible for chromosome pairing, we induce crossing over between distantly related chromosomes and transfer genes for resistance to pests, diseases and environmental stresses from related species to wheat.
