摘要:

为了解新疆裸重唇鱼的生化遗传特性,丰富新疆裸重唇鱼种质资源研究的内容,借助聚丙烯胺凝胶对新疆裸重唇鱼5种组织(心脏、眼睛晶状体、肝脏、肾脏和脾脏)中的乳酸脱氢酶(LDH)、苹果酸脱氢酶(MDH)以及酯酶(EST)进行了电泳分析。结果表明:新疆裸重唇鱼的LDH、MDH和EST同工酶系统具有个体差异性和组织特异性。组织特异性主要表现在同工酶位点表达及其表达活性程度不同两方面,可能受遗传和代谢双重调控,与各组织执行生理功能密切相关。LDH-C基因只在肝脏中表达,酶谱图上靠近阴极附近,为典型“肝带”。新疆裸重唇鱼同工酶个体差异性可能是其在漫长的进化过程中为了能适应特殊生境的需要。新疆裸重唇鱼心脏中上清液型苹果酸脱氢酶(s-MDH)最多表达出6条酶带,可能是新疆裸重唇鱼在进化过程中四倍体化使基因重复的结果。研究结果可从生化遗传角度为新疆裸重唇鱼种质资源保护利用提供一定理论依据。

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
