Abstract

The sy19 mutation, which impairs the homology of meiotic chromosome synapsis in rye, were mapped using a specially created F2 population by means of isozyme Acph1 locus and microsatellite (SSR) markers. The sy19 gene was localized in the chromosome 7R in the pericentromeric region of long arm based on the linked inheritance with the Acph1 locus. The locus was linked with five rye SSR markers, with the Xrems1234 locus being located closest to the sy19 gene (6.4 cM). The genetic map of the analyzed chromosome 7R region includes ten markers and the sy19 locus. A possible function of the Sy1 and Sy19 genes based on the data on comparative genomics is discussed.
