Genetic Analysis of Isozyme Loci in Adenophora potaninii Korsh.

Ge Song and Hong De-yuan   

Abstract: Enzyme polymorphism in Adenophora potaninii Korsh. was investigated using vertical slab polyacrylamide gel electrophoresis. Genetic analysis of the population samples and the progeny of intraspecific crosses allowed the verification of the isozyme loci from eight enzyme systems. The system studies included aspartate aminotransferase (AAT), esterase (EST). formate dehydrogenase (FDH), glutamate dehydrogenase (GDH), isocitrate dehydrogenase (IDH), lactate dehydrogenase (LDH), malic enzyme (ME) and superoxide dismutase (SOD). The results indicated that the eight enzyme systems are specified by at least 18 loci, 12 of which behaved as al|ozyme loci. Zymogram patterns showed that EST is monomeric and GDH is hexameric. AAT, FDH, IDH and SOD are apparently dimeric. The tissue and developmental variability are also discussed along with the genetic analysis of isozymes.
