GAPC — Daucus carota subsp. sativus

Summary

DCAR_011294 (GAPC, DcGAPC) on carrot chromosome 3 encodes a glyceraldehyde-3-phosphate dehydrogenase (NADP) with additional annotated activities including fructose-bisphosphate aldolase, phospholipase D, voltage-gated anion channel, and histone acetyltransferase. The gene is associated with glycolytic, gluconeogenic, and pentose-phosphate shunt processes, as well as aerobic respiration, redox and ROS metabolism, anoxia and UV responses, phosphatidic acid metabolism, auxin polar transport, and epigenetic regulation via RdDM. It localizes to multiple compartments including the plasma membrane, mitochondrial envelope, chloroplast envelope, vacuole, and cell wall. Associations with agronomic traits include grain yield, photosynthetic rate, respiration rate, root morphology and thickness, stem and leaf senescence, seedling growth, germinability at low temperature, and responses to drought, salinity, freezing, high temperature, UV-B, cadmium, ethylene, and auxin. Related genes in other species are linked to drought resistance, leaf senescence, thermotolerance, chilling tolerance, and disease resistance.
