title: Alcohol dehydrogenase of Biomphalaria glabrata (Molusca: Pulmonata): polymorphism, genetic analysis, and interspecific variations.
abstract: Alcohol dehydrogenase of Biomphalaria glabrata has been characterized by electrophoresis, substrate specificities, and other physiochemical means. It exists as a multiple molecular form possessing a minimum number of three bands in ovotestis, five in digestive gland, and six in albumen gland. Each organ shows characteristic electrophoretic forms which differ in substrate specificities and the response to the organomercurial inhibitor p-hydroxymercuribenzoate. Mercaptoethanol treatment has no effect on any electrophoretic form. Genetic analyses of the electrophoretic variants show that three different loci are responsible for the synthesis of the various electrophoretic forms observed in this species. Different species vary in their electrophoretic patterns. A possible role of alcohol dehydrogenase isozymes in the phylogenetic relationship among three species, B. glabrata, B. tenagophila, and B. straminea, has been discussed.
