    Journal: Appl Plant Sci; 2014 Mar; 2(3):. PubMed ID: 25202608.
    Abstract:
    PREMISE OF THE STUDY: Vigna unguiculata is an economically important legume, and the complexity of its variability and evolution needs to be further understood. Based on publicly available databases, we developed chloroplast microsatellite primers to investigate genetic diversity within V. unguiculata and its related species Phaseolus vulgaris. • METHODS AND RESULTS: Twelve polymorphic chloroplast microsatellite markers were developed and characterized in 62 V. unguiculata individuals. The number of alleles per locus varied between two and four, the unbiased haploid diversity per locus ranged from 0.123 to 0.497, and the polymorphism information content varied from 0.114 to 0.369. In cross-species amplifications, nine of these markers showed polymorphism in 29 P. vulgaris individuals. • CONCLUSIONS: The newly developed chloroplast microsatellite markers exhibit variation in V. unguiculata as well as their transferability in P. vulgaris. These markers can be used to investigate genetic diversity and evolution in V. unguiculata and P. vulgaris.
