GSH2 — Triticum aestivum

Summary

TaGSH2 (TRAESCS6A02G140800) on wheat chromosome 6A encodes a glutathione synthase (EC 6.3.2.3) with glutathione synthase activity, glutathione binding, ATP binding, and magnesium binding, and forms a homodimer. This gene is associated with glutathione anabolism, nucleotide salvage, and primary metabolism, and its product localizes to the plastid and cytosol. TaGSH2 has been connected to flag leaf senescence, grain filling period, grain weight, grain yield, harvest index, grain protein content, plant height, drought tolerance, and stomatal resistance. It is also linked to root growth, seedling development, cadmium tolerance, ozone tolerance, cesium stress tolerance, jasmonate hypersensitivity, and endoplasmic reticulum stress response. Studies of related genes in other species link the family to stress tolerance, cadmium resistance, phytochelatin synthesis, and salinity stress tolerance.
