GR — Arabidopsis thaliana

Summary

AT3G54660 (GR, GR2) encodes a glutathione reductase (EC 1.8.1.7) with glutathione reductase activity, NADP binding, FAD binding, and protein translocase activity. This gene is associated with cellular redox homeostasis, reactive oxygen species response, antioxidant activity, and photosynthetic redox state response in Arabidopsis thaliana. GR2 is linked to glutathione accumulation, methionine and cysteine accumulation, sulfur assimilation, and growth under sulfur deficiency. It is associated with heat and cold tolerance, as well as ethylene sensitivity, high and low temperature stress responses, photosynthetic rate, leaf senescence, root meristem development, stomatal opening, chlorophyll content, and embryo development traits. The protein localizes to mitochondria, chloroplast stroma, and plastids, and is associated with glutathione metabolism, the ascorbate-glutathione cycle, mitochondrial protein import, and tetrapyrrole biosynthesis.
