Screening and effect analysis of specific small molecule inhibitors of programmed death moleculesin plant

Abstract

objective to conduct a screen for small molecule inhibitors that can inhibit programmed death of plant molecules and test their inhibitory effects. Methods small molecule drugs with inhibitory or alleviating effects on programmed death of plant cells were selected by screening a large number of literatures, and the indexes of plant root length and fresh weight, Results H2S could reduce the inhibition of root length and fresh weight of Cucumber Seedlings by Cd in a concentration dependent effect. CD induced the accumulation of endogenous H2S, indicating that H2S is involved in the response to CD. H2S reduces ROS accumulation and membrane lipid peroxidation by activating antioxidant systems. H2S reduces apical cell death by decreasing oxidative damage. Conclusions elevated endogenous H2S levels negatively regulate programmed death molecules in plants.
