GR — Solanum lycopersicum

Summary

SOLYC09G065900.3 (GR) on tomato chromosome 9 encodes a protein with glutathione reductase, thioredoxin reductase (NADPH), dihydrolipoyl dehydrogenase (NADH), and leghemoglobin reductase activities, along with FAD/NAD- and copper-binding domains. The gene is associated with cell redox homeostasis, glutathione metabolism, oxidative stress response, cellular respiration, ascorbate biosynthesis, and mitochondrial protein import. It localizes to mitochondrial membranes, the glycine cleavage system, and chloroplast stroma. GR is linked to fruit ripening, ethylene sensitivity, drought tolerance, low-temperature stress tolerance, aluminum tolerance, cadmium tolerance, blossom-end rot resistance, net photosynthetic rate, root morphology, germination rate, and fungal disease response. Related genes in other species are linked to embryo development, leaf senescence, stomatal aperture, and glutathione redox homeostasis.
