Molecular markers are important tools that have been used to identify the short arm of rye chromosome 1R 1RS which contains many useful genes introgressed into wheat background.
Wheat expressed sequence tag EST sequences are valuable for developing molecular markers since ESTs are derived from gene transcripts and more likely to be conserved between wheat and its relative species. In the present study, 35 sequence-tagged site STS primers were designed based on EST sequences distributed on homology group 1 chromosomes of Triticum aestivum and used to screen specific markers for chromosome 1RS of Secale cereale. Two primer pairs different from the early studies, STS WE3 , which amplified a bp and a bp fragment, and STS WE , which produced a bp fragment from rye genome, were proved to be specific to chromosome 1RS since the corresponding fragments were only amplified from 1R chromosome addition line and wheat-rye lines with chromosome 1RS, but not from wheat-rye 2R-7R chromosome addition lines and the other lines lacking chromosome 1RS.
The specific fragments of 1RS were amplified in 4 wheat-rye lines, but not in the other lines. Download to read the full article text. An, D. Introgression of resistance to powdery mildew conferred by chromosome 2R by crossing wheat nullisomic 2D with rye.
