| Outline of Research at the Start |
Abscisic acid (ABA) regulates plant responses and adaption to stress. Although accumulated ABA triggers such plant-physiological processes, how plants rapidly produce ABA remains to be elucidated. ABA is produced by the multi-step biosynthesis and the single-step hydrolysis of inactive ABA glucosides. Recently, we reported that the latter reaction occurs quickly preceding the former and is activated by stress-induced organellar dynamics involving membrane protein trafficking. We will investigate the mechanism for such quick ABA production as a crucial early step for plant stress adaptation.
