G6PD5 — Capsicum annuum

Summary

CaG6PD5 (T459_07126) on pepper chromosome 2 encodes a glucose-6-phosphate 1-dehydrogenase (EC 1.1.1.49) with NADP binding activity, placing it in the pentose-phosphate shunt. The gene is associated with glucose metabolism, cellular respiration, reactive nitrogen species metabolism, protein oxidation, regulation of hormone levels, fruit ripening, cell death, and homeostasis. Its product localises to the cytosol, chloroplast stroma, and cytoplasmic side of the endoplasmic reticulum membrane. CaG6PD5 has been connected to pungency, respiration rate, root-knot nematode resistance and susceptibility, salt tolerance, oxidative stress tolerance, ABA sensitivity, root growth, seed germination, seed oil content, and NADPH production. Studies of related genes in other species link the family to salt stress tolerance, biomass accumulation, and carbon metabolism.
