OBJECTIVE: To reveal the population structure of Pomacea spp. using genetic markers so as to provide the evidence for studying the invasion and expansion of it in the mainland of China.
METHODS: The genetics of 581 specimens of Pomacea spp. from 60 sites was analyzed by sequencing CO I gene. The diversity of nucleotide and haplotypes were calculated in DnaSP 5.10.01. The haplotype network analysis was performed in Network 4.2.0.1. A phylogenetic tree was produced based on the haplotypes from the present study and those available from GenBank in order to understand the taxonomic status of Pomacea spp. in China.
RESULTS: A total of 556 sequences were acquired in the present study and produced 25 unique haplotypes. Six haplotypes frequently occurred in the specimens and accounted for 96.0%. The phylogenetic analysis identified two Pomacea species in China, i. e. P. canaliculata and P. insularum. The usage of haplotypes of P. insularum in China reversed from the existing pattern in other countries.
CONCLUSION: The complexity of population structure of Pomacea spp. in the mainland of China indicates multi-original introduction and complicated expansion patterns.
