DTC — Beta vulgaris subsp. vulgaris

Summary

BvDTC (BVRB_7G180120) encodes a protein with domains including Mito_Metabolite_Transporter, MCP, MCP_transmembrane, and MCP_dom_sf, and has oxidative phosphorylation uncoupler activity and multiple transmembrane transporter activities including for tricarboxylic and dicarboxylic acids, coenzyme A, and thiamine diphosphate. The protein localises to mitochondrial and plastid inner membranes. In sugar beet, BvDTC is associated with cellular respiration, photorespiration, lipogenesis, lipolysis, mitochondrial biogenesis, proton transmembrane transport, ethylene signalling, and downregulation of defence responses. It has been linked to respiration rate, osmotic response sensitivity, ethylene sensitivity, leaf composition, plant growth and development, and salt tolerance. Associations with oxidative stress response, primary root growth, fertility, hypoxia tolerance, photosynthetic efficiency, cold acclimation, and grey mould resistance have also been reported. Related genes in other species connect the family to drought, salt, and cold tolerance, mitochondrial proton conductance, and organic acid levels.
