GAPC — Pisum sativum

Summary

PSAT1G133920, designated GAPC (PsGAPC), encodes a protein with glyceraldehyde-3-phosphate dehydrogenase (NADP) activity, glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity, fructose-bisphosphate aldolase activity, phospholipase D activity, voltage-gated monoatomic anion channel activity, and histone H3K18 acetyltransferase activity. The gene is associated with glycolytic, gluconeogenic, pentose-phosphate shunt, and oxidative phosphorylation processes, as well as redox signal response, phosphatidic acid metabolism, and retrograde response. It localizes to the plasma membrane region, mitochondrial envelope, chloroplast envelope, plant cell papilla, and microtubule cytoskeleton. GAPC is linked to grain yield, drought tolerance, salt tolerance, freezing tolerance, disease tolerance, stem senescence, leaf senescence, photoperiod sensitivity, and seed oil accumulation. Studies of related genes in other species link the family to glycolytic pathway function, actin organization, and stress responses including drought resistance and chilling tolerance.
