Recent increase in the availability of expressed sequence tag (EST) data has facilitated the development of microsatellite or simple sequence repeat (SSR) markers in a number of plant species groups, including cereals. As these SSRs are derived from ESTs/genes (EST-SSRs), they exhibit a higher potential for transfer through cross-amplification in related species than SSR markers generated from genomic DNA libraries. In this study, a sub-set of 165 EST-SSR markers from a total of 185 assigned to the genetic map of barley was examined for transferability to wheat, rye and rice. A higher proportion, i.e., 78.2% of barley markers showed amplification in wheat followed by 75.2% in rye and 42.4% in rice. Furthermore, in silico comparison of SSR-ESTs (ESTs containing SSRs) corresponding to 185 mapped barley EST-SSR loci against 1,369,182 publicly available cereal ESTs showed significant homology with …
