| Outline of Final Research Achievements |
Abscisic acid (ABA) is an essential plant hormone in environmental stress responses such as seed dormancy, drought tolerance and salt tolerance. In this study, we aimed to identify unknown ABA receptors that are different from the known ABA receptor PYL and to elucidate a new signaling pathway of ABA (non-PYL pathway). We succeeded in selecting candidate genes for novel ABA receptors involved in the non-PYL pathway by a combination of biochemical and chemical genetic methods using antagonists of PYL with specific bioactivity.
