CSD1 — Oryza sativa Japonica

Summary

Rice gene CSD1 (Os03g0351500, also known as CSD2, CSD3, SOD1, SOD2, SODCC1) encodes a copper/zinc superoxide dismutase (SOD) family protein with copper-binding and superoxide dismutase activity (EC 1.15.1.1). The gene is associated with oxidative stress tolerance, salt stress tolerance, drought tolerance, and aluminum tolerance in rice. It has been linked to bacterial blight disease resistance, heat tolerance, grain yield, spikelet fertility, seedling vigor, photosynthetic rate, and stomatal complex closure time. The encoded protein localizes to the thylakoid, chloroplast stroma, apoplast, cytosol, and plasmodesmata. The gene is also associated with cellular responses to ozone, high light intensity, UV-B, copper, and chitin, as well as hydrogen peroxide biosynthesis and superoxide removal. Studies of related genes in other species link the gene family to defense responses, fungal and bacterial disease resistance, and zinc deficiency response.
