TH9 — triticum aestivum

Summary

TRAESCS1A02G112400, designated TaTH9 on wheat chromosome 1A, encodes a thioredoxin H-type-like protein with oxidoreductase activity acting on a sulfur group of donors with disulfide as acceptor, and protein-disulfide reductase activity. This gene is associated with redox sensing, chlorophyll a anabolism, pre-harvest sprouting, hormone metabolism, and secondary metabolite biosynthesis. It has been linked to grain protein content, grain yield, days to maturity, heat tolerance, drought tolerance, chlorophyll content, stomatal resistance, root length, and salt tolerance. The product localises to the plastid, cytosol, and plasmalemma. Studies of related genes in other species link the family to oxidative stress response and disulfide isomerase activity.
