GAPC — Capsicum annuum

Summary

CaGAPC (T459_27594) 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 ascorbate-glutathione cycling, as well as redox signalling, autophagy, and auxin polar transport. It localises to multiple cellular compartments including the plasma membrane, mitochondrial envelope, chloroplast envelope, vacuole, and cell wall. CaGAPC is linked to agronomically important traits including grain yield, photosynthetic rate, respiration rate, drought and salinity tolerance, freezing tolerance, disease tolerance, UV-B sensitivity, ethylene and auxin sensitivity, stomatal closure, and root and shoot development. Studies of related genes in other species connect the GAPC family to stress tolerance, basal immunity, and actin organisation.
