GAPC — Pisum sativum

Summary

PSAT2G076560, designated PsGAPC, encodes a glyceraldehyde-3-phosphate dehydrogenase (GAPDH) on garden pea chromosome 2LG1. The product possesses glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) and NADP-dependent activities, along with fructose-bisphosphate aldolase, phospholipase D, voltage-gated anion channel, and histone acetyltransferase functions. It is associated with glycolytic, gluconeogenic, pentose-phosphate, and oxidative phosphorylation pathways, as well as cellular respiration, redox signal response, phosphatidic acid metabolism, and responses to anoxia and ROS metabolic process. The protein localises to the plasma membrane region, mitochondrial envelope, chloroplast envelope, vacuole, apoplast, and plant-type cell wall. PsGAPC is linked to grain yield, drought tolerance, salt tolerance, freezing tolerance, stomatal closure, root morphology, stem senescence, photoperiod sensitivity, auxin sensitivity, and disease tolerance. Studies of related genes in other species connect the GAPC family to biomass, leaf senescence, heat and chilling tolerance, and basal immunity.
