Vicia Faba L

By means of pharmacological approach and stomatal analysis，the role of G protein in light-regulated stomatal movement in Vicia faba L. was studied. The result shows that CTX, the activator of heterotrimeric G protein α-subunit, induced stomatal closure under light, but this effect can be reversed by ascorbic acid(Vc) and catalase(CAT). It indicated that G protein was blunted by light, and H2O2 may be one downsteam signal molecule in G protein participated light-regulated stomatal movement.
