5种虾虎鱼类线粒体COI基因序列变异及系统进化
Sequence Variation and Molecular Phylogeny of Mitochondrial COI Gene Segments from Five Species of Gobiidae Family
摘要
Abstract
45 mitochondrialCOI gene sequences offive kinds of goby juvenilesfrom Mangroves of Leizhou region were obtained,andtheaverage content ofT, C,A, Gwere29.9%, 28.4%, 23.9%, 17.8%, respectively.A total of23 haplotypes were found with 184 variable nucleotide positions,and the haplotype proportionofTridentiger bifasciatuswas thehighest(80.0%), and that ofGobiopterus lacustris was thelowest(18.2%).The inter- and intra-specific genetic distances (Kimura two-parameter, K2P) ranged from 0.1376 to 0.2635, and0.0000 to 0.0208, respectively.Based onNeighbor-Joining and Maximum Likelihood phylogenetic tree,among thegobiesclustered intofive branches, Mugilogobius abeiandM. chulaeare in theclosest relationship,while the relationship between Gobiopterus lacustris and the other fourpopulations is a little far.The neutrality tests indicated thatG. lacustriswasdominated by moderate-frequency allelic loci, while there were a large number of low-frequency allelic loci withinthe other fourpopulations.关键词
