VATA — Cucumis sativus

Summary

CSA_7G447770, designated VATA (also known as VHA-A or CsVHA-A) on cucumber chromosome 7, encodes the catalytic A subunit of the vacuolar-type H⁺-ATPase (V-ATPase) V1 domain, a proton-transporting ATPase that operates by a rotational mechanism and possesses ATP hydrolase activity. This gene is associated with a wide range of biological processes including proton transmembrane transport, ATP metabolism, cell cycle regulation (G1/S phase transition, symmetric and asymmetric cell division), seed trichome initiation and elongation, very-long-chain fatty acid metabolism, and response to zinc. It is linked to numerous agronomically relevant traits such as root volume and length, leaf senescence, disease tolerance, salt and temperature stress responses, herbicide sensitivity, and shoot apical meristem development. The V-ATPase subunit localises to the tonoplast, vacuole, nuclear envelope, and preprophase band. Related genes in other species are linked to cell cycle control, salt tolerance, and pollen development.
