Aquaporins are water channel proteins of intracellular and plasma membranes that play a crucial role in plant water relations. The family of aquaporins, also called water channels or major intrinsic proteins, is characterized by six transmembrane domains that together facilitate the transport of water and a variety of low molecular weight solutes. Understanding of plant response mechanisms will aid in strategies aimed at improving stress tolerance in crop plants. Recent progress was made in understanding the molecular bases of aquaporin transport selectivity and gating. On the other hand, pathogens utilize aquaporins to mediate reactive oxygen species (ROS) signaling and regulate their normal growth, development, secondary or specialized metabolite production and pathogenicity.

The plasma membrane forms a permeable barrier that separates the cytoplasm from the external environment, defining the physical and chemical limits in each cell in all organisms. FUNCTIONS OF PLANT AQUAPORINS 1.Water transport in plant roots and leaves 2.Plant nutrient acquisition. Plant aquaporins: multifunctional water and solute channels with expanding roles. Aquaporins (AQPs) are a class of small, membrane channel proteins present in a wide range of organisms. They facilitate the rapid, passive exchange of water across cell membranes and are responsible for up to 95% of the water permeability of plasma membranes (Henzler and Steudle, 2004).
