GRXC1 — Cicer arietinum

Summary

CaGRXC1 (GRXC1, LOC101493651) on chickpea chromosome 5 encodes a glutaredoxin family protein with glutathione disulfide oxidoreductase activity, 2Fe-2S cluster binding, and redox activity. It is associated with the ascorbate-glutathione cycle, glutathione and cysteine anabolism, cellular response to oxidative stress, nitrogen fixation, cell wall modification, root and flower morphogenesis, seed germination, pollen development, and salt response. The gene is linked to traits including net photosynthetic rate, water use efficiency, protein content, stomatal resistance, photochemical quenching, and salt tolerance. It localizes to the cytosol and endoplasmic reticulum. Studies of related genes in other species connect the family to phosphorus uptake and embryo development, but these associations are not yet established in chickpea.
