GR — Phaseolus vulgaris

Summary

PHAVU_007G177200, designated PvGR or PvGR2 on chromosome 7 of French bean (Phaseolus vulgaris), encodes a protein with domains including GSHR, GSHR/TRXR-like, Pyr_nuc-diS_OxRdtase, and FAD/NAD-binding domains. It is associated with leghemoglobin reductase activity, dihydrolipoyl dehydrogenase (NADH) activity, glutathione reductase activity, thioredoxin reductase (NADPH) activity, protein translocase activity, and binding of FAD, NADP, copper, metals, ATP, and protein. The gene is associated with cell redox homeostasis, cellular response to oxidative stress, glutathione metabolism, 2-oxoglutarate metabolism, glycine decarboxylation, mitochondrial biogenesis, and protein import into the mitochondrial outer membrane and matrix. It is linked to photosynthetic rate, root morphology, amino acid content, oxidative stress tolerance, photosystem II function, leaf senescence, embryo development, root apical meristem maintenance, stomatal aperture, drought stress response, and glutathione redox homeostasis. Related genes in other species link the family to redox homeostasis, oxidative stress response, heat and cold tolerance, root growth, sulfur assimilation, and glutathione accumulation.
