G6PD5 — Pisum sativum

Summary

PsG6PD5 (PSAT1G084200) on chromosome 1LG6 encodes a glucose-6-phosphate 1-dehydrogenase (EC 1.1.1.49) with NADP binding activity, belonging to the G6P_DH family. The enzyme is associated with the pentose-phosphate shunt, glucose metabolism, cellular respiration, fermentation, the TCA cycle, starch breakdown, sucrose metabolism, nitrate assimilation, nitrogen fixation, the ascorbate glutathione cycle, protein oxidation, and seed germination. It is linked to response to folic acid and is localized to the cytosol, chloroplast stroma, and cytoplasmic side of the endoplasmic reticulum membrane. The gene is associated with sucrose and starch content, proline content, germination rate, root length, root growth, salt tolerance, oxidative stress tolerance, NADPH production, ABA sensitivity, seed oil content, and both resistance and susceptibility to root-knot nematode. Studies of related genes in other species link the family to salt stress tolerance and biomass accumulation.
