[ Metbod] By employing polyacrylamide gel electrophoresis method, the expressions of AMY and SOD isozymes during seed germination process were analyzed. ~ Result] The main AMY bands remained strong during the whole peri- od and a new band A2 appeared in the middle and late period of seed germination. Some new SOD bands occurred at the early stage, then be- came weak or disappeared in the middle period, and band S6 became intense in the late peried. [ Conclusion.] The expression of AMY and SOD isozyme gene has temporal difference during germination of E. henryi Oliv seeds.展开更多

[Method] Non-denaturing polyacrylamide gel electrophoresis was used to analyze isozyme patterns such as esterase (EST),acid phosphatase (ACP),ATP enzyme (ATPase),amylase (AMY),superoxide dismutase (SOD) and peroxidase (POD) in long-term subculture callus of Emmenopterys henryi Oliv. [Result] The research showed that there were differences among the 6 kinds of isozymes in embryogenic callus and non-embryogenic callus of Emmenopterys henryi Oliv.,and both levels could be taken as the basis for identification,the EST,ACP,and POD of non-embryogenic callus were significantly higher than embryogenic callus. The browning of non-embryogenic callus was non-level in the AMY,SOD and POD isozymes when was compared with normal non-embryogenic callus,while the EST,ACP and ATPase isozymes decreased; When the browning of embryogenic callus was contrasted with normal embryogenic callus,EST isozyme increased and the other 5 kinds of enzymes decreased. [Conclusion] The study provided theoretical basis for research morphological difference and browning of long-term tissue culture of Emmenopterys henryi Oliv..展开更多
