G6PD5 — Solanum tuberosum

Summary

PGSC0003DMG400020269 (symbol G6PD5, also known as StG6PD5 or StG6PD6) on potato chromosome 2 encodes a glucose-6-phosphate 1-dehydrogenase (EC 1.1.1.49) with NADP binding activity, belonging to the G6P_DH family. The encoded protein is associated with the pentose-phosphate shunt, glucose and carbohydrate metabolism, starch and sucrose anabolism and breakdown, protein synthesis, protein phosphorylation, post-translational modification, homeostasis, nitric oxide storage, and response to cold. It localises to the chloroplast stroma, cytosol, and cytoplasmic side of the endoplasmic reticulum membrane. The gene has been connected to starch yield, reducing sugar and sucrose content, water use efficiency, respiration rate, salt tolerance, root growth, oxidative stress tolerance, ABA sensitivity, seed germination, and both resistance and susceptibility to root-knot nematode. Related genes in other species link the family to salt stress tolerance and biomass accumulation.
