TH9 (TRAESCS1D02G114000) — triticum aestivum

Summary

TaTH9, encoded by the bread wheat gene TRAESCS1D02G114000 on chromosome 1D, is a thioredoxin H-type-like protein with oxidoreductase activity acting on sulfur-group donors, protein-disulfide reductase activity, and enzyme inhibitor activity. It is associated with redox sensing, chlorophyll a anabolism, protein storage, pre-harvest sprouting, hormone metabolism, carbohydrate transport, secondary metabolite biosynthesis, fatty acid metabolism, photorespiration, wax anabolism, and response to freezing. The protein localises to the plastid, cytosol, and plasmalemma. TaTH9 is associated with grain iron and zinc content, grain protein content, grain yield per plant, harvest index, test weight, stand establishment, plant vigor, water use efficiency, net photosynthetic rate, and drought sensitivity. Studies of related genes in other species connect the family to oxidative stress response.
