Abstract excerpt

We recently demonstrated that yeast elicitor (YEL)-induced stomatal closure requires a Ca(2+)-dependent kinase, CPK6. A Ca(2+)-independent kinase, Open Stomata 1 (OST1), is involved in stomatal closure induced by various stimuli including ABA. In the present study, we investigated the role of OST1 in YEL-induced stomatal closure in Arabidopsis using a knock-out mutant, ost1-3, and a kinase-deficient mutant,...
