摘要：

Nine polymorphic microsatellites markers were identified for Galaxea fascicularis symbionts and characterized in 29 samples from two populations. Four of them were derived from coral genome with 5-11 alleles, and the expected and observed heterozygosities ranging 0.67-0.89 and 0.25-0.69 respectively. Five were derived from zooxanthella genome amplified 0-3 alleles/locus per individual, while 2-4 alleles/locus with totally 13 genotypes in the two populations, which likely implied multiple DNA-polymorphic Symbiodinium species associated with single host and the populations. The genetic diversity of the two coral host populations was significantly greater than that of zooxanthella populations. These markers should be useful in various genetic applications involving both the coral host and the zooxanthella.
