ALLOZYME MARKERS IN SCALLOP MIZUHOPECTEN- YESSOENSIS JAY

In a search for reliable gene markers for population studies of scallo p (Mizuhopecten yessoensis), seven highly polymorphic markers were sel ected from more than 30 proteins examined: glucose-6-phosphate isomera se, aspartate aminotransferase, esterase D, glutathione reductase, oct opine dehydrogenase, phosphoglucomutase, and a water-soluble muscle pr otein. AH these proteins were analyzed by electrophoresis in starch ge l using the same buffer system. Their activity was high even after pro longed storage of frozen tissue samples (as tissue, the adductor muscl e was used). Good allozyme separation and repeatability of results all owed us to avoid errors in genotype scoring. Identification of allozym e phenotypes of these proteins, detected in scallop by different autho rs, was conducted.
