CSD1 — Zea mays

Summary

ZmCSD1 (ZM00001EB016940) on maize chromosome 1 encodes a protein with SOD_Cu/Zn domains and is annotated with copper binding and superoxide dismutase activity (EC 1.15.1.1). The gene is associated with removal of superoxide radicals, cellular responses to ozone, high light intensity, UV-B, and copper, as well as oxidative phosphorylation and lipid A metabolism. It localizes to the thylakoid, chloroplast stroma, cytosol, apoplast, and plasmodesmata. ZmCSD1 is associated with grain yield, grain number, ear length, seed longevity and viability, plant height, root length, leaf chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, and tolerance to drought, salt, and bacterial blight. Related genes in other species are associated with oxidative stress tolerance, aluminum tolerance, and fungal disease resistance.
