Base on the analysis, organophosphate inducible system has been established by treatment of the swimming seedling and drenching roots with organophosphate solution. This inducible system consists of model plant Arabidopsis thaliana and methamidophos, folimat or methyl parathion which are the representative types of highly toxical OPs. Meanwhile, the responses of the esterase isozymes and the total soluble proteins to OPs in Arabidopsis thaliana have been detected by Native-PAGE and SDS-PAGE.
