Abstract:In the present study,the population genetic structure and population genetic diversity of Mytilus coruscus along Zhej iang and Fuj ian coast waters were investigated by the mitochondrial COI gene.A 564 bp fragment was edited and aligned.The results showed that high level of haplotype diver-sity,nucleotide diversity and mean number of pairwise differences were detected for M.coruscus.Both the neighbor-j oining trees and haplotype networks showed that no significant genealogical structures corresponding to sampling locations existed,but a small clade with high bootstrap was detected.Net-work of M.coruscus was star-like which indicated signature of population expansion.Pairwise FST re-vealed no significant genetic differentiation among populations and not significant after sequential Bon-ferroni corrections.Both Tajima's (D=-1.828,P=0.017)and Fu's (Fs=-22.954,P=0.000)gave negative values,and both tests were significant,which indicated M.coruscus might have experienced a recent population expansion.
