* Phylogenetic analysis of Pomacea canaliculata isolates collected from rice fields in different origins of China by combined mitochondrial 12S and 16S genes.
- To study the genetic relationships of Pomacea canaliculata collected from rice fields in China, the mitochondrial (mt) 12S and 16S of 9 P. canaliculata isolates from 5 southern provinces in China were sequenced and analyzed. The intra-specific sequence variations of P. canaliculata were 0-1.1% for 12S and 0--0.6% for 16S, while the inter-specific variations among common Pomacea species in mt 12S and 16S were 3.0-11.7% and 2.3-10.1%, respectively. Phylogenetic analysis based on combined sequences of mt 12S and 16S revealed complex genetic structure of P. canaliculata in China. Two phylogenetic groups of P. canaliculata were indicated in China with one group sistered to P. canaliculata isolates from USA, and two groups were even found in the same province. The phylogenetic relationships of Pomacea spp. also could be effectively inferred by combined sequences of mt 12S and 16S. These findings provided basic information for further study of population genetics and diffusion pattern of P. canaliculata in China as well as in the world.
