Os08g0564000
The rice Os08g0564000 was reported as OsPT6 in 2009 [1] by researchers from the China.

Annotated Information
Gene Symbol
- Os08g0564000 <=> OsPT6
Function
- OsPT6 plays a broad role in Pi uptake and translocation throughout the plant.
Expression
- Expression of both genes OsPht1;2 (OsPT2) and OsPht1;6 (OsPT6) increased significantly under Pi deprivation in roots and shoots. By using transgenic rice plants expressing the GUS reporter gene, driven by their promoters, we detected that OsPT2 was localized exclusively in the stele of primary and lateral roots, whereas OsPT6 was expressed in both epidermal and cortical cells of the younger primary and lateral roots.
Evolution
- OsPT6, but not OsPT2, was able to complement a yeast Pi uptake mutant in the highaffinity concentration range.
- In transgenic rice, the knock-down of either OsPT2 or OsPT6 expression by RNA interference significantly decreased both the uptake and the long-distance transport of Pi from roots to shoots.
