DTC — Beta vulgaris subsp. vulgaris

Summary

BvDTC (BVRB_5G112640) on sugar beet chromosome 5 encodes an uncoupling protein, a member of the mitochondrial metabolite transporter family. The gene product is annotated with oxidative phosphorylation uncoupler activity and multiple transmembrane transporter activities, including for tricarboxylic and dicarboxylic acids, coenzyme A, and thiamine diphosphate. BvDTC is associated with mitochondrial membrane permeability regulation, cellular respiration, photorespiration, lipogenesis, and lipolysis. It localizes to the mitochondrial inner membrane, chloroplast inner membrane, and amyloplast inner membrane. The gene is linked to traits including respiration rate, osmotic response sensitivity, ethylene sensitivity, leaf composition, and plant growth and development. Associations with primary root growth, fertility, hypoxia tolerance, photosynthetic efficiency, cold acclimation, and gray mold resistance have also been noted. Studies of related genes in other species connect the family to drought and salt tolerance, oxidative stress tolerance, and mitochondrial uncoupling.
