한국산 논우렁이과 ( Family Viviparidae ) 2종에서의 동위효소 변이

Isozyme Variability in Two Species of Freshwater Viviparid Snails in Korea : Cipangopaludina chinensis malleata and C. Japonica

Abstract

A horizontal starch gel electrophoresis for enzyme proteins extracted from 2 species of Korean viviparid snails; Cipangopaludina chinensis malleata and C. japonica was carried out in order to elucidate their genetic relationships. A total of 10 enzymes were employed in three different kinds of buffer systems. Two loci from each enzyme of alcohol dehydrogenase, esterase, glucose phosphate isomerase, isocitrate dehydrogenase, iditol dehydrogenase, malate dehydrogenase and peptidase(VL); and only one locus dach from two enzymes, glycerlo-3-phosphate dehydrogenase and phosphoglucomutase were detected; but, four loci from peptidase(LGG) were observed. Most of loci in two viviparid species showed homozygous monomorphic banding patterns and some of them were specific as genetic markers between two different species. However, EST-1, MDH-1, PEP(VL)-1loci showed polymorphic banding patterns. Foru populations of C. chinensis malleata were more closely clustered in a dendrogram within the range of genetic identity values of 0.928-1.00, and these clusters were lineated with C. japonica at the value of 0.355. In summarizing the above results, two viviparid snail species dmployed in this study mostly showed monomorphic enzyme protein banding patterns, and genetic differences specific between two species.
