Genetic diversity based on RAPD of the fifteen wild freshwater mussel species in South Dongting Lake
2009
RAPD technology was used to study fifteen wild freshwater mussel species in South Dongting Lake, and 11 random primers were selected . 1 775 RAPD bands have been obtained, length between 500 bp and 1 500 bp, its band rate of primer 43.5, these bands have revealed genetic diversity maps of the fifteen wild freshwater mussel species in south dongting lake. Genetic analysis of these mussels indicated, the closest genetic distance among genera is 0.485 7, between Schistodesmus and Acuticosta, the farthest is 0.729 2,between Lamprotula and the others. The closest genetic distance among species is 0.333 3, between Cuneopsis heudei and Cuneopsis capitata, the farthest is 0.678 2, between Lamprotula triclavus and Lamprotula zonata. Lamprotula and Ptychorhychus pfisteri is Ambleminae. Anodonta is Amodontinae. Acuticosta, Unio, Arconaia, Cuneopsis, Lanceolaria, Schistodesmus, Arconaia is Unioninae.
