CSD2 — Brassica oleracea

Summary

BoCSD2 (CSD2) on cabbage chromosome 4 encodes a copper/zinc superoxide dismutase, an enzyme that catalyses the removal of superoxide radicals. The gene is associated with superoxide dismutase activity, copper binding, and protein kinase activity, and its product localises to the thylakoid, chloroplast stroma, apoplast and plasma membrane. BoCSD2 is associated with cellular responses to oxidative stress, ozone, UV-B, light intensity, chitin, and bacterial molecules, as well as with fermentation, gluconeogenesis, nitrate import, and gene silencing by miRNA. Trait associations include nitrate content and uptake, photosynthetic rate, biomass yield, bacterial blight disease resistance, leaf chlorosis, and salt tolerance. Related genes in other species link the family to superoxide detoxification, zinc deficiency response, and bacterial and fungal disease resistance.
