GAPC — Beta vulgaris subsp. vulgaris

Summary

BvGAPC (BVRB_6G151550) on sugar beet chromosome 6 encodes a protein with glyceraldehyde-3-phosphate dehydrogenase domains and NAD(P)-binding domains, and is annotated with glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity, fructose-bisphosphate aldolase activity, phospholipase D activity, voltage-gated monoatomic anion channel activity, histone acetyltransferase activity, and salicylic acid binding. The gene is associated with glycolysis, gluconeogenesis, the pentose-phosphate shunt, aerobic respiration, redox and ROS metabolism, anoxia and UV responses, auxin polar transport, phosphatidic acid and pectin metabolism, and melatonin anabolism. It localizes to the plasma membrane, mitochondria, chloroplast envelope, vacuole, cell wall, and microtubule cytoskeleton. Associations include grain yield, starch content, chlorophyll content, photosynthetic and respiration rates, root morphology and thickness, stem and leaf senescence, floral development, germinability at low temperature, and tolerance to drought, salinity, freezing, high temperature, UV-B, and disease. Studies of related genes in other species link the GAPC family to biomass, drought resistance, leaf senescence, thermotolerance, grain yield, and chilling tolerance.
