GRX — Cicer arietinum

Summary

AhGRX, located on chickpea chromosome 6, encodes a glutaredoxin family protein with glutathione disulfide oxidoreductase activity, 2Fe-2S cluster binding, and enzyme activator activity. It is associated with cellular response to oxidative stress, iron-sulfur cluster assembly, nitrogen fixation, nodulation, and jasmonic acid anabolism. The gene is linked to anther development, seed germination, chlorophyll fluorescence, and photosynthetic traits including net photosynthetic rate, stomatal resistance, and respiration rate. It is associated with plant growth and development, embryo development, root morphology, and oxidative stress tolerance. The protein localizes to the cytoplasm, nucleus, chloroplast stroma, plastid, mitochondria, and cytosol. Studies of related genes in other species have linked the family to water use efficiency, soluble protein content, and photochemical quenching.
