• Information
  • Symbol: OsPAP10a
  • MSU: LOC_Os01g56880
  • RAPdb: Os01g0776600
• Publication
  • Overexpression of OsPAP10a, a root-associated acid phosphatase, increased extracellular organic phosphorus utilization in rice, 2012, J Integr Plant Biol.
• Genbank accession number
  • AK071643
• Key message
  • In gel activity assays of root and shoot protein extracts, it was revealed that OsPAP10a is a major acid phosphatase isoform induced by Pi starvation
  • Constitutive overexpression of OsPAP10a results in a significant increase of phosphatase activity in both shoot and root protein extracts
  • In vivo root 5-bromo-4-chloro-3-indolyl-phosphate (BCIP) assays and activity measurements on external media showed that OsPAP10a is a root-associated APase
  • Overexpression of OsPAP10a, a root-associated acid phosphatase, increased extracellular organic phosphorus utilization in rice
  • The transcript abundance of OsPAP10a is specifically induced by Pi deficiency and is controlled by OsPHR2, the central transcription factor controlling Pi homeostasis
  • These results indicate that OsPAP10a can potentially be used for crop breeding to improve the efficiency of P use
• Connection
  • OsPAP10a, OsPHR2, Overexpression of OsPAP10a, a root-associated acid phosphatase, increased extracellular organic phosphorus utilization in rice, The transcript abundance of OsPAP10a is specifically induced by Pi deficiency and is controlled by OsPHR2, the central transcription factor controlling Pi homeostasis
