This gene codes Arabidopsis vacuolar proton-pumping pyrophos- phatase (H+-PPase) gene (AVP1). AVP1 uses energy derived from the hydrolysis of cytosolic inorganic pyrophosphate (PPi) to orthophosphate (Pi) to actively pump protons into vacuoles. This increases acidification in vacuole, which establishes a difference in electrochemical potential for H+ across the tonoplast. The difference is used by other vacuolar transporters, such as Na+/H+ antiporters. By this process, transgenic plants overexpressing AVP1 can facilitate sequestration of Na+ into vacuole from cytoplasm  and survive under high salt conditions

This is a vacuolar H+-pyrophosphatase of Arabidopsis thaliana. This protein functions as a proton pump on the vacuolar membrane. Several papers have found that overexpression of AVP1 increases the salt tolerance of some plants such as tomato, rice and cotton. Experiments carried out on transgenic plants showed that as the AVP1 expression level increased the accumulation and retention of solutes was higher than that of the wild type.

TDH3-AVP1-6xHis-CYC

This is a vacuolar H+-pyrophosphatase of Arabidopsis thaliana. This protein functions as a proton pump on the vacuolar membrane. Several papers have found that overexpression of AVP1 increases the salt tolerance of some plants such as tomato, rice and cotton. Experiments carried out on transgenic plants showed that as the AVP1 expression level increased the accumulation and retention of solutes was higher than that of the wild type.
