GAPC — Beta vulgaris subsp. vulgaris

Summary

BvGAPC (BVRB_5G110740) on sugar beet chromosome 5 encodes a protein with glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity, NAD+ binding, NADP binding, fructose-bisphosphate aldolase activity, phospholipase D activity, voltage-gated monoatomic anion channel activity, and histone acetyltransferase activity. It is associated with glycolysis, amino acid and carbohydrate metabolism, anaerobic respiration, phloem unloading, nitrogen utilization, and proline, glutamate, pectin, and phosphatidic acid metabolism. The gene is linked to grain yield, root weight and thickness, starch content, chlorophyll content, photosynthetic rate, seedling vigor, germinability at low temperature, and responses to drought, salinity, freezing, UV-B, high temperature, and ethylene and auxin. It is also connected to stomatal closure, leaf and stem senescence, floral development, disease tolerance, and mitochondrial localization. Studies of related genes in other species link the GAPC family to biomass, grain yield, thermotolerance, chilling tolerance, disease resistance, and actin organization.
