GPX1 — triticum aestivum

Summary

TaGPX1 (TRAESCS7B02G054400) on chromosome 7B encodes a phospholipid-hydroperoxide glutathione peroxidase with glutathione peroxidase and peroxidase activities, containing a thioredoxin domain and belonging to the glutathione peroxidase family. The gene is associated with photosynthesis, including light harvesting in photosystem II, as well as carotenoid biosynthesis and glutathione redox reactions. It has been linked to several agronomically important traits, including grain yield, seed dormancy, seed germination, stripe rust, drought tolerance, osmotic adjustment capacity, and salinity tolerance. The encoded protein localizes to the chloroplast stroma and cytosol. Studies of related genes in other species link the family to osmotic stress and salinity tolerance.
