Abstract

In order to determine boundaries of genetic recombination among putative 'species' of endosymbiotic dinoflagellates, nine polymorphic microsatellite loci were developed and optimized for clade B Symbiodinium designated as type 7 (B7) and two related types, B13 and B13a. Together, they form a subclade in clade B that is specific to Caribbean corals in the genus Madracis. A total of 52 samples were analysed (including 43 B7, 2 B13, 7 B13a) originating from seven Caribbean locations. Diversity indices at each haploid locus ranged from 0.302 to 0.836 and four to 14 alleles were found per locus. The loci were preliminarily cross-tested on closely related 'ancestral' B1 populations found in maze coral Meandrina meandrites and that of another host specialist, B5, from the lesser starlet coral Siderastrea radians.
