| Abstract: | Objective] To study the role of G protein in light-regulated stomatal movement in Vicia faba L..Method] The means of pharmacological approach and stomatal analysis were adopted to study the role of G protein in light-regulated stomatal movement.Result] CTX induced stomatal closure under light,and it can be reversed by ascorbic acid and catalase.Conclusion] G protein was blunted by light,and H2O2 may be the downsteam signal in G protein participated signal pathway. |
