GAPC — Brassica oleracea

Summary

BoGAPC (BOLC102_C05P011400.1) on cabbage chromosome 5 encodes a glyceraldehyde-3-phosphate dehydrogenase (GAPDH) family protein with NAD(P)-binding and catalytic domains. The enzyme exhibits glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity, along with associated fructose-bisphosphate aldolase, phospholipase D, histone acetyltransferase, and voltage-gated anion channel activities. BoGAPC is associated with glycolytic, gluconeogenic, pentose-phosphate shunt, and oxidative phosphorylation processes, as well as redox signal response, ROS metabolic process, lipoxygenase pathway, and phosphatidic acid metabolism. It localises to multiple cellular compartments including chloroplast and mitochondrial envelopes, plasma membrane, vacuole, cell wall, and apoplast. The gene is associated with agronomically important traits such as grain yield, photosynthetic rate, heterosis, self-incompatibility, cytoplasmic male sterility, stress responses (high/low temperature, UV-B, salinity, drought), disease tolerance, root and shoot development, leaf and stem senescence, and seed germination at low temperature.
