Abstract:
Objective To analyze the genetic diversity of snail populations from five provinces in China mainland. Methods Genomic DNA was amplified by random primer and the products were electrophoresed by 8% polyacrylamide and stained by 0.6% silver nitrogen. The results were recorded and analyzed. Results The average similarity and match percentage among the nine snail populations were 0. 721 4 and 0. 680 9 respectively. The cluster trees showed that the nine snail populations could be divided into three groups ; snails from Dali of Yunnan Province and Puge of Sichuan Province were the first isolated group; snails from Fuqing of Fujian Province and Dongtai of Jiangsu Province were clustered into the second group; the other four populations from Anhui Province and snails from Yixing of Jiangsu Province belong to the last group. Conclusion There is a large diversity among smooth-shelled snails in China although close relationship exists. The cluster trees gained by different snail populations are basically the same and consistent with the distribution of these populations. However, further study should be carried out on the cluster of smooth-shelled snails from Dongtai of Jiangsu Province.
