TH9 (TRAESCS1B02G132600) — triticum aestivum

Summary

TaTH9 (TRAESCS1B02G132600) on wheat chromosome 1B encodes a thioredoxin H-type-like protein with oxidoreductase activity acting on sulfur-group donors and protein-disulfide reductase activity, and is also associated with enzyme inhibitor activity and protein binding. The gene is associated with redox sensing, chlorophyll a anabolism, pre-harvest sprouting, hormone metabolism, secondary metabolite biosynthesis, and fatty acid metabolism, as well as response to freezing and photorespiration. It is 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.
