Abstract:

Proton pumps are types of important enzymes that promote proton(H+)transmembrane transport and cause potential difference between the membrane and participate in a variety of life processes. Organic acids are mainly stored in vacuoles and proton pump promotes proton transmembrane transport accompanied by energy release,which then provides power for the transmembrane transport and storage of organic acids in vacuoles. This paper focuses on the categories,structural characteristics and regulatory factors of proton pumps related to acid transport in horticultural plants,as well as the research status of different types of proton pumps in the regulation of organic acid accumulation,in order to provide reference for the research and regulation of proton pumps and organic acid accumulation in horticultural plants,and then provide a theoretical basis for regulating the quality of horticultural plants.

Key words: horticultural plant, organic acid, proton pump, fruit, regulating of quality
