GAPC — Triticum aestivum

Summary

TRAESCS7B02G213300, designated TaGAPC on bread wheat chromosome 7B, encodes a glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) with oxidoreductase activity acting on the aldehyde or oxo group of donors, NAD or NADP as acceptor, and also annotated for fructose-bisphosphate aldolase activity, phospholipase D activity, voltage-gated monoatomic anion channel activity, and salicylic acid binding. The gene is associated with cytosolic glycolysis, carbohydrate and amino acid metabolism, and a wide range of biological processes including ascorbate metabolism, redox signal response, response to anoxia, and pre-harvest sprouting. It has been linked to numerous agronomic traits such as grain yield, grain width and length, flour color, stem and culm strength, spike density, heading time, photoperiod sensitivity, stem rust, and stress tolerances including drought, salt, freezing, and UV-B light sensitivity. The protein localizes to multiple cellular compartments including the plasma membrane region, mitochondrial envelope, chloroplast envelope, vacuole, and apoplast. Studies of related genes in other species connect the GAPC family to drought, salt, heat, and chilling stress tolerance, grain yield, leaf senescence, and disease resistance.
