Gene Details:

• MSU gene ID: LOC_Os09g15670
• RAPdb gene ID: Os09g0325700
• Gene Symbol: OsSIPP2C1 OsPP2C68 OsPP108
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsSIPP2C1 expression was up-regulated by high salt, PEG6000 and exogenous ABA, and enhanced in the abl1 mutant under normal, salt, or drought condition.
• Interestingly, OsSIPP2C1 expression was increased during the early panicle development.
• Together, it is suggested that a nuclear PP2C protein OsSIPP2C1 negatively regulated by ABL1 is involved in abiotic stress and panicle development in rice.
• 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).
• Genetic analysis revealed that Arabidopsis plants overexpressing OsPP108 are highly insensitive to ABA and tolerant to high salt and mannitol stresses during seed germination, root growth and overall seedling growth.
• At adult stage, OsPP108 overexpression leads to high tolerance to salt, mannitol and drought stresses with far better physiological parameters such as water loss, fresh weight, chlorophyll content and photosynthetic potential (Fv/Fm) in transgenic Arabidopsis plants.
• Expression profile of various stress marker genes in OsPP108 overexpressing plants revealed interplay of ABA dependent and independent pathway for abiotic stress tolerance.
