GLRX — Solanum tuberosum

Summary

PGSC0003DMG400019088 (symbol GLRX, also known as GRX3) on potato chromosome 6 encodes a glutaredoxin with glutathione disulfide oxidoreductase activity, 2Fe-2S cluster binding, and redox activity. The gene is associated with cell redox homeostasis, cellular response to oxidative stress, photoprotection, and immune and defense responses. It is linked to hormone metabolism and anabolism, secondary metabolism, virus-induced PTGS, and seed germination. Associations with response to water, drought tolerance, water use efficiency, quantum yield, and root length are reported. The encoded protein localizes to the cytosol, plastid, ER, Golgi, secretory vesicle, plant-type vacuole, and plasmalemma. Studies of related genes in other species link the family to protein glutathionylation.
