MAP Kinases, MPK9 and MPK12, Regulate Chitosan-Induced Stomatal Closure
Copyright policy )MAP Kinases, MPK9 and MPK12, Regulate Chitosan-Induced Stomatal Closure
Chitosan (CHT)-induced stomatal closure was inhibited by an MAPKK inhibitor, PD98059, and was impaired in mpk9 mpk12 but not in mpk9 or mpk12. CHT induced the production of reactive oxygen species, cytosolic alkalization, and cytosolic Ca(2+) oscillation in mpk9 mpk12. These results suggest that MPK9 and MPK12 are involved in CHT-induced stomatal closure.
