Changes in plasma membrane lipids, aquaporins and proton pump of broccoli roots, as an adaptation mechanism to salinity

The lipid composition and PIP1 and PIP2 aquaporin expression of plasma membrane vesicles of broccoli roots were evaluated for different levels of NaCl. Long time salt exposition caused an increase in the abundance of two PIPs isoforms and modified membrane lipid composition. These changes could affect the membrane stability and control the water permeability, as a mechanism of acclimation to salinity.
