Abstract
Hydrogen sulfide (H2S) and hydrogen peroxide (H2O2) as important plant signaling molecules both participate in ethylene induced stomatal closure in Arabidopsis thaliana, but the relationship between them is unclear. So we used A. thaliana wide type and related mutants as materials to study the interaction between H2S and H2O2 in mediating ethylene induced stomatal closure. The results showed that ethylene triggered raise of H2S content and L-/D-cysteine desulfhydrase (L-/D-CDes) activity as well as stomatal closure in leaves of A. thaliana wild type, but not in those of H2O2 deficient mutants AtrbohD, AtrbohF, Atpao2 and Atpao4, ethylene induced increase in H2O2 content in H2S deficient mutants Atl-cdes and Atd-cdes, but couldn’t induce stomatal closure. H2O2 scavenger and synthesis inhibitors depressed the inducing effect of ethylene on H2S content, L-/D-CDes activity as well as stomatal closure in leaves of A. thaliana. However, although H2S scavenger and synthesis inhibitors suppressed ethylene-induced stomatal closure, but had no significant effect on ethylene-induced increase in H2O2 content in guard cells of A. thaliana. From these data it can be deduced that H2S acts downstream of H2O2 mediating ethylene-induce stomatal closure in A. thaliana.
