VP — Daucus carota subsp. sativus

Summary

DCAR_006358, designated DcVP on carrot chromosome 2, encodes a member of the PPase-energised H-pump family with proton-translocating pyrophosphatase and inorganic diphosphatase activities. The gene is associated with proton transmembrane transport, establishment of transmembrane electrochemical gradients, and localisation to the tonoplast, vacuolar membrane, Golgi cis cisterna, and endosome. DcVP is linked to cell wall pectin metabolism, sucrose metabolism, auxin polar transport, regulation of starch biosynthesis, cold acclimation, and responses to abscisic acid, salinity, and thirst. It is associated with leaf length, biomass yield, stomatal opening, root growth, fruit development, salt tolerance, and transplant survival. Related genes in other species are linked to drought tolerance, phosphorus use efficiency, and grain yield.
