Abstract

Simple sequence repeat (SSR) or microsatellite markers are a valuable tool for several purposes such as evaluation of genetic diversity, fingerprinting, marker-assisted selection and breeding. In this study, a SSR genomic enriched library was developed in Lathyrus sativus (grass pea) by affinity capture of restriction fragments to biotinylated microsatellite oligonucleotides. About 400 randomly selected clones were sequenced, and SSRs were present in approximately 30% of them. Clones contained 75%, 9% and 16% of simple, interrupted and compound SSRs, respectively. Of the 10 SSRs tested, 7 primer pairs produced clearly distinguishable DNA banding patterns. Successively, SSR primer pairs were successfully tested to reveal polymorphism in a set of four different grass pea germplasm accessions. The transferability of SSR markers was high among three related species of Lathyrus, namely Lathyrus cicera, Lathyrus ochrus and Lathyrus tingitanus, and the legume crop, Pisum sativum. These results indicate that the novel SSR markers are informative and will be useful and convenient for genetic analysis in grass pea and related species.
