Annotated Information
Gene Symbol
- Os09g0541000 <=> OsPIP2;7, PIP2.7, PIP2-7, OsPIP2-6
Function
- OsPIP2;7 was involved in rapid water transport and maintenance of the water balance in cells, and ultimately improves the tolerance of yeast and rice to low temperature stress.
Phenotypic analysis
- Yeast cells overexpressing OsPIP2;7 showed a higher survival rate after freeze–thaw stress.
- Furthermore, OsPIP2;7 enhanced the transpiration rate and tolerance to low temperature when overexpressed in rice.
Expression
- OsPIP2;7 was generally up-regulated in roots but down-regulated in shoots at the early stage of chilling stress.
Subcellular localization
- OsPIP2;7 was localized mainly in mesophyll cells of leaves.
- In roots OsPIP2;7 was detected in the vascular tissues, epidermis cells and exodermis cells at the elongation zone, as well as in the epidermis cells, exodermis cells and root hair at the maturation zone.
