The rice Os03g0150600 was reported as OsPT1 in 2012 [1] by researchers from China.
Contents
Annotated Information
Function
- OsPT1 is a key member of the Pht1 family involved in Pi uptake and translocation in rice under Pi-replete conditions.
- OsPT1 expression was strongly enhanced by the mutation of Phosphate Overaccumulator2 (OsPHO2) but not by Phosphate Starvation Response2, indicating that OsPT1 is involved in the OsPHO2-regulated Pi pathway.
Phenotypic analysis
- Transgenic plants of OsPT1 overexpression lines and RNA interference knockdown lines contained significantly higher and lower phosphorus concentrations, respectively, compared with the wild-type control in Pi-sufficient shoots.
- These responses of the transgenic plants to Pi supply were further confirmed by the changes in depolarization of root cell membrane potential, root hair occurrence, 33 P uptake rate and transportation, as well as phosphorus accumulation in young leaves at Pi-sufficient levels.
Expression
- OsPT1 was expressed abundantly and constitutively in various cell types of both roots and shoots.
Evolution
- OsPT1 was able to complement the proton-coupled Pi transporter activities in a yeast mutant defective in Pi uptake.
