Microsatellite markers previously developed for other leguminous species were tested for cross-genus transferability and evaluated for their potential usefulness in providing an improved assessment of the genetic relationships between two closely related taxa belonging to Onobrychis genus (Fabaceae). Candidate microsatellite markers were tested for polymorphism and replicability in sixteen populations of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. and O. montana. Out of the 23 SSRs, there were identified seven polymorphic loci. In total 32 alleles were detected and the number of alleles per locus varied from two to six. PIC values ranged from 0.375 to 0.6454, and four SSRs displayed a PIC > 0.5. Relative uniform rates of genetic diversity were obtained. In case of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. the observed and expected heterozygosity ranged from 0.100 to 0.952 and from 0.219 to 0.525, respectively, while for O. montana ranged from 0.166 to 0.750 and from 0.083 to 0.375, respectively. Seven polymorphic SSRs with clear and reproducible amplification were identified. These markers proved to be very efficient for unambiguous population discrimination based on both geographic and taxonomic criteria. Hereafter, these SSR markers can be used as tools for evolutionary studies in Onobrychis genus, as well in providing knowledge on patterns of the species phylogeography. |
