Gene Details:

• MSU gene ID: LOC_Os06g43640
• RAPdb gene ID: Os06g0643900
• Gene Symbol: OsSAP1 OsPAP26
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Their stress-inducible expression provided the protection against yield loss in transgenic plants, indicating the agronomic relevance of OsSAP11 and OsRLCK253 in conferring abiotic stress tolerance.
• Functionally, both OsSAP11 and OsRLCK253 could improve the water-deficit and salt stress tolerance in transgenic Arabidopsis plants via a signaling pathway affecting the expression of several common endogenous genes.
• While the abundance of OsPAP26 transcript is not affected by Pi supply, it is upregulated during leaf senescence.
• Furthermore, Pi deprivation and leaf senescence greatly increased the abundance of OsPAP26 protein.
• Overexpression or RNA interference (RNAi) of OsPAP26 in transgenic rice significantly increased or reduced APase activities in leaves, roots and growth medium, respectively.
• Western blot analysis of protein extracts from callus growth medium confirmed that OsPAP26 is a secreted PAP.
• OsPAP26-overexpressing plants were capable of converting more ATP into inorganic Pi in the growth medium, which further supported the potential role of OsPAP26 in utilizing organic P in rhizosphere.
• In summary, we concluded that OsPAP26 perform dual functions in plants: Pi remobilization from senescing to non-senescing leaves and organic P utilization.
• OsPAP26 encodes a major purple acid phosphatase and regulates phosphate remobilization in rice.
