Application of two microsatellite sequences in wheat storage proteins as molecular markers

Abstract

In eukaryotes, tandem arrays of simple-sequence repeat sequences can find applications as highly variable and multi-allelic PCR-based genetic markers. In hexaploid bread wheat, a large-genome inbreeding species with low levels of RFLP, di- and trinucleotide tandem repeats were found in 22 published gene sequences, two of which were converted to PCR-based markers. These were shown to be genome-specific and displayed high levels of variation. These characteristics make them especially suitable for intervarietal breeding applications.
