DMAS1 — Triticum aestivum

Summary

TRAESCS1D02G281300 (symbol DMAS1, preferred name DMAS1-B) on bread wheat chromosome 1D encodes a NADP-dependent oxidoreductase domain-containing protein belonging to the AKR4C aldo/keto reductase family. The enzyme has 3''-deamino-3''-oxonicotianamine reductase activity and aldose reductase (NADPH) activity, acting on CH-OH group donors with NAD or NADP as acceptor. This gene is associated with cellular response to zinc starvation, siderophore anabolism, indole alkaloid anabolism, response to iron ion starvation, and secondary metabolite biosynthesis. It is linked to grain iron content, grain zinc content, zinc content trait, and grain protein content. The protein localises to the cytosol. Studies of related genes in other species connect the family to EC 1.1.1.440 and EC 1.1.1.21.
