General Information

General Information Comment Organism
malfunction genetically engineered plants having their OsPCS1 expression silenced via RNA interference (OsPCS1 RNAi) show no significant difference phenotype compared to wild-type plants. Treatment with buthionine sulfoximine, an inhibitor of GSH biosynthesis, significantly decreases Cd and As tolerance of rice seedlings. Concentrations of thiol peptides in the roots of OsPCS RNAi plants grown under Cd stress, overview Oryza sativa Japonica Group
malfunction genetically engineered plants having their OsPCS2 expression silenced via RNA interference (OsPCS2 RNAi) contain less phytochelatins (PCs) and more glutathione (GSH), the substrate of PC synthesis by PCS, than wild-type plants. OsPCS2 RNAi plants are sensitive to As(III) stress, but Cd tolerance is little affected. Treatment with buthionine sulfoximine, an inhibitor of GSH biosynthesis, significantly decreases Cd and As tolerance of rice seedlings. Concentrations of thiol peptides in the roots of OsPCS RNAi plants grown under Cd stress, overview Oryza sativa Japonica Group
physiological function isozyme OsPCS2 is a major isozyme controlling phytochelatin (PC) synthesis, and PCs are important for As tolerance in rice. PC synthesis may make a smaller contribution to Cd tolerance in rice. Synthesis of thiol peptides in response to Cd or As(III) stress in rice roots Oryza sativa Japonica Group
