SOD — Cucumis sativus

Summary

CSA_1G573600 (SOD, also known as CSD1) encodes a copper/zinc superoxide dismutase, an enzyme with superoxide dismutase activity (EC 1.15.1.1) that binds copper and is associated with reactive oxygen species homeostasis and detoxification. In cucumber, this gene is associated with numerous agronomic traits including fruit fresh weight, stem fresh weight, seedling height, root volume, harvest index, leaf chlorophyll content, and bacterial blight disease resistance. It is linked to tolerance of drought, salt, chilling, heat, hypoxia, low light, and oxidative stress, as well as to copper homeostasis. The encoded protein localizes to the cytosol, nucleus, plasmalemma, and extracellular regions. Studies of related genes in other species connect the family to salt tolerance, superoxide detoxification, and defense responses against fungal and bacterial pathogens.
