Isolation of polymorphic microsatellite markers from Hymeniacidon sinapium (Porifera: Demospongiae: Halichondrida)


S. Hoshino, E-mail:


Eight dinucleotide microsatellite markers were developed on Hymeniacidon sinapium (Porifera: Demospongiae), common littoral sponge around Japan, to investigate population genetic structure. Two to 10 alleles were identified in an analysis of 24 individuals of H. sinapium, with observed heterozygosity ranging from 0.04 to 0.83. All loci did not deviate from the Hardy–Weinberg expectations; however, significant linkage disequilibrium between Sinp126 and Sinp142 was found.
