CSD1 — Phaseolus vulgaris

Summary

PHAVU_006G097000, designated PvCSD1, encodes a protein with a copper-zinc superoxide dismutase domain on chromosome 6 of French bean (Phaseolus vulgaris). The product is annotated with superoxide dismutase activity, copper binding, and additional functions including protein kinase activity and chitosan binding. PvCSD1 is associated with cellular responses to oxidative stress, ozone, UV-B, light intensity, copper, and sucrose stimulus, as well as cysteine homeostasis, gene silencing by miRNA, and fermentation. The gene is linked to traits including bacterial blight disease resistance, photosynthetic rate, anthocyanin content, proline content, stomatal complex closure time, and salt tolerance. Phenotypic associations include oxidative stress tolerance, high light stress tolerance, thermotolerance, copper homeostasis, disease resistance, and arsenic tolerance. The protein localizes to the cytosol, nucleus, plasmalemma, plasmodesma, and plant-type vacuole. Related genes in other species link the family to superoxide detoxification, bacterial and fungal disease resistance, and innate immunity.
