Gene Details:

Functional Descriptions:

  • Microarray analysis of transgenic plants overexpressing OsNAP revealed that many stress-related genes were up-regulated, including OsPP2C06/OsABI2, OsPP2C09, OsPP2C68 and OsSalT, and some genes coding for stress-related transcription factors (OsDREB1A, OsMYB2, OsAP37 and OsAP59).
  • OsPP2C09 positively affected plant growth but acted as a negative regulator of drought tolerance through ABA signaling.
  • The transcript and protein levels of OsPP2C09 were rapidly induced by exogenous ABA treatments, which suppressed excessive ABA signaling and plant growth arrest.
  • This study shed new light on the roles of OsPP2C09 in coordinating plant growth and drought tolerance.
  • The OsPP2C09 protein interacted with the core components of abscisic acid (ABA) signaling and showed PP2C phosphatase activity in vitro.
  • Further analysis showed that OsPP2C09 interacts with DRE-binding (DREB) transcription factors and activates reporters containing DRE.
  • By contrast, overexpression of the OsPYL/RCAR3-interacting protein OsPP2C09 rendered plant growth more sensitive to osmotic stress.
  • We conclude that, through activating DRE-containing promoters, OsPP2C09 positively regulates the drought response regulon and activates an ABA-independent signaling pathway.
  • OsPP2C09 Is a Bifunctional Regulator in Both ABA-Dependent and Independent Abiotic Stress Signaling Pathways.
