Development of microsatellite loci for Cryptocarya mandioccana Meisner (Lauraceae) and their genotyping success in different tissues

ABSTRACT Nine polymorphic microsatellite loci were isolated and characterized for Cryptocarya mandioccana Meisner, a tree from the Atlantic Rainforest with seeds dispersed by large animals. The loci were characterized using 48 individuals from two populations and their genotyping success tested in four tissues: leaves from adults and seedlings, and two diaspore maternal tissues. Maternity analyses were also performed on diaspores and leaves from nine adult trees. The number of alleles per locus ranged from nine to 15 and the observed and expected heterozygosities ranged from 0.214 to 0.864 and 0.745 to 0.892, respectively. The loci genotyping success did not significantly differ between tissues and varied from 56 to 96%. The microsatellites showed enough polymorphism to assign the nine adult trees to their diaspores. The successful genotyping in all tissues and identification of mother trees show that the microsatellites are suitable for studies such as spatial genetic structure and maternity analyses.
