One of most highly expressed aquaporin gene in the leaves and roots of rice, highly responsible to environmental stresses.[1]
Contents
Introduction
According to the nomenclature of PIP genes in maize, this gene has been designated as OsPIP1-1. PIP genes are the protein encoding genes of plasma membrane intrinsic proteins (PIPs) -- a subfamily of aquaporins that enable fast and controlled translocation of water across the membrane. There are recently 10 designated PIP genes in the gnome of rice, they are classified into two groups, that is OsPIP1-1 to OsPIP1-3 and OsPIP2-1 to OsPIP2-7, based on the similarity of their amino acid sequences.[2] The ubiquitously expression of OsPIP1-1 gene in rice leaves and roots indicates its important physiological role.
Function
Experiments show that when transiently expressed as EGFP-OsPIP1 in rice cell protoplasts, it is mainly distributed in cytoplasm, While co-expressing with EGFP-OsPIP1 make it re -translocate to plasma membrane. This observation is further confirmed by the water permeability measuring experiment.[1]
Seed germination
Transgenic rice seeds with overexpressed OsPIP1 exhibit a significant higher germination rate than the control, this is consistent with the higher α-amylase activity in transgenic seeds.[1]
Salt tolerance
Experiments show that when not overexpressed at high level,OsPIP1 will efficiently promote salt resistance in rice, but when has high OsPIP1 expression level, rice will become more sensitive to high salt environment than control.[1]
Seed yield
Transgenic rice plants with various OsPIP1 express level show that, appropriate low level of overexpressed OsPIP1 will increase seed yield, while high level of OsPIP1 expression will decrease seed yield, and extremely high expression will even make rice sterile.[1]
Expression
From the data in 2006, we can see OsPIP1 is highly expressed in both the roots and leavels of rice, with transcript copy numbers more than 10^3.[2]
