Function
Figure 1. Growth of WT and transgenic plants cultured in soil pots.[1].
- The rice (Oryza sativa) purple acid phosphatase 10a (OsPAP10a) belongs to group Ia of purple acid phosphatases (PAPs), and clusters with the principal secreted PAPs in a variety of plant species including Arabidopsis.
- OsPAP10a can potentially be used for crop breeding to improve the efficiency of P use.
Phenotypic analysis
- 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.
- Furthermore, overexpression of OsPAP10a significantly improved ATP hydrolysis and utilization compared with wild type plants.
Expression
- The transcript abundance of OsPAP10a is specifically induced by Pi deficiency and is controlled by OsPHR2, the central transcription factor controlling Pi homeostasis. 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.
Evolution
- In plants, the PAP family has been previously classified into seven groups and OsPAP10abelongs to group Ia. In rice, group Ia contains 5 members, namely OsPAP10a to OsPAP10d, and OsPAP26.
