- Key message
- Biochemically, OsPAP21b showed hydrolysis of several organophosphates at acidic pH and possessed sufficient thermostability befitting for high temperature rice ecosystems with acidic soils
- Interestingly, OsPAP21b was revealed to be a secretory PAP and encodes a distinguishable major APase (acid phosphatase) isoform under low Pi in roots
- In light of these evidences, present study strongly proposes OsPAP21b as a useful candidate for improving Pi acquisition and utilization in rice
- Connection
- OsPAP21b, OsPHR2, Improvement of Phosphate Acquisition and Utilization by a Secretory Purple Acid Phosphatase OsPAP21b in Rice., OsPAP21b was found to be under the transcriptional control of OsPHR2 and strictly regulated by plant Pi-status at both transcript and protein levels
- OsPAP21b, OsPIE1, A phosphate-starvation induced RING-type E3 ligase maintains phosphate homeostasis partially through OsSPX2 in rice., Under Pi-sufficient condition, overexpression of OsPIE1 upregulated the expression of OsPT2, OsPT3, OsPT10 and OsPAP21b, resulting in Pi accumulation and acid phosphatases (APases) induction in roots
