GAPC — Capsicum annuum

Summary

CaGAPC (T459_27945) on pepper chromosome 11 encodes a glyceraldehyde-3-phosphate dehydrogenase (NAD+) with additional annotated activities including fructose-bisphosphate aldolase, phospholipase D, voltage-gated anion channel, and histone acetyltransferase functions. The gene is associated with core metabolic processes such as glycolysis, gluconeogenesis, the pentose-phosphate shunt, TCA cycle, and aerobic respiration, as well as redox signalling, ROS metabolism, autophagy, and auxin polar transport. It localises to multiple cellular compartments including the plasma membrane, mitochondria, chloroplast envelope, vacuole, and cell wall. CaGAPC is associated with agronomically important traits including grain yield, photosynthetic rate, drought and salinity tolerance, freezing tolerance, disease tolerance, UV-B sensitivity, ethylene and auxin sensitivity, stomatal closure, root morphology, and leaf and stem senescence. Related genes in other species connect the family to additional processes such as thermotolerance, chilling tolerance, basal immunity, and actin organisation.
