Abstract:

This paper was to learn about the biochemical heredity characteristics and to enrich the research data about the germplasm resources of Gymnodiptychus dybowskii.Lactate dehydrogenase(LDH)isozymes,malate dehydrogenase(MDH)isozymes and Esterase(EST)isozymes in five kinds of tissues(heart,crystalline lens,liver,kidney and spleen)of Gymnodiptychus dybowskii were preliminarily studied by using the vertical polyacrylamide gel electrophoresis.The results showed that:LDH isozymes,MDH isozymes and EST isozymes showed tissue specificity and individual variations.The tissue specificity mainly reflected in expression of isozyme sites and degree of isozyme activity,which may be regulated by both heredity and metabolism and were related to the specific physiological functions of various kinds of tissues.LDH-C gene only expressed in liver.Its isozyme bands were near to negative pole in electrophoretogram, which were typical liver bands.In order to adapt the unique habitant,the isozymes of Gymnodiptychus dybowskii showed individual variations.Six supernate type of MDH isozyme bands expressed in heart may be the result of gene redundancy due to tetraploid during the evolution of Gymnodiptychus dybowskii.The research results could provide theoretical basis for the conservation and utilization of germolasm resources for Gymnodiptychus dybowskii from the biochemical genetics level.

Key words: Gymnodiptychus dybowskii, LDH isozymes, MDH isozymes, EST isozymes, Tissue specificity, Individual variations
