                                    Citation: Reddy, U.K., Padmavathi, N., Saha, S., Besong, S., Bates, G.T., Katam, R., Saha, S., Jenkins, J.N., Stommel, J.R., Quirin, E. 2003. Allelic plasticity of simple sequence repeats among domesticated and wild species of capsicum. Plant and Animal Genome Conference Proceedings. p. 523.Interpretive Summary: None required.
                                Technical Abstract: The genus Capsicum comprises >30 species, among which, five major cultivated species (C. annuum, C. chinense, C. frutescens, C. baccatum and C. pubescens) are well known. In the present study we used 25 SSRs known to be polymorphic between annuum, frutescens and chinense types.  The objective of the study is to understand the extent of gene flow within the domesticated forms and to further understand the genetic bottlenecks to improve the commonly cultivated species for different purposes such as food and ornamental uses. Our study identified distinct diagnostic SSR alleles to identify various cultivated and wild taxa. The average number of alleles per microsatellite being 5 (range 2-9 alleles per locus), this class of markers appears to be highly polymorphic. We further observed a high degree of convergence in allele sharing rather than the conserved motifs.
