Development of microsatellite markers for the Mediterranean gorgonian coral Corallium rubrum

Corallium rubrum, an endemic Mediterranean gorgonian coral, has undergone an intensive exploitation leading to the extinction of local commercial banks and changes in the structure and dynamics of coastal populations. Management and conservation of this species requires a better understanding of the genetic structuring and connectivity among populations. With this aim, seven microsatellite loci have been isolated. All loci were polymorphic with allele numbers ranging from five to 26 and observed heterozygosity ranging from 0.18 to 0.68. Significant deviations from Hardy–Weinberg expected genotype frequencies due to heterozygote deficiency were detected at all loci.
