Gene Details:

• MSU gene ID: LOC_Os05g46040
• RAPdb gene ID: Os05g0537400
• Gene Symbol: OsABIL3 OsPP2C50
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Transgenic Arabidopsis plants overexpressing OsPP2C50 and OsPP2C50FM changed ABA sensitivity, validating the in vitro results.
• The effects of the second and forth residues on the interaction of OsPP2C50 with several OsPYL/RCAR proteins were investigated by systematic mutagenesis.
• The water-mediated interaction between the wedging Trp-259 of OsPP2C50 and pyrabactin is lost, undermining the structural integrity of the ABA receptor:co-receptor.
• OsPP2C50 and OsPP2C53 is major negative regulators of ABA signaling regarding stomata closing in rice.
• We identified that only OsPP2C50 and OsPP2C53 among 9 OsPP2CAs might be related with stomatal closure/opening signaling based on guard cell specific expression and subcellular localization.
• Transgenic rice overexpressing OsPP2C50 and OsPP2C53 showed significantly higher water loss than control.
