SOD — Solanum lycopersicum

Summary

SlSOD (SOLYC01G067740.3) on tomato chromosome 1 encodes a copper/zinc superoxide dismutase, annotated with superoxide dismutase activity, copper binding, and protein homodimerization activity. The gene is associated with cellular responses to ozone, UV-B, light intensity, sucrose, copper, and oxidative stress, as well as the xanthophyll cycle, nonphotochemical quenching, energy homeostasis, and cellular respiration. It has been linked to leaf flattening, high light stress tolerance, oxidative stress tolerance, thermotolerance, arsenic and salt stress responses, and copper homeostasis. Associations also include traits such as net photosynthetic rate, chlorophyll content, anthocyanin content, starch and sugar content, germination rate, root length, stem length, bacterial blight disease resistance, and stomatal resistance. The protein localises to the cytosol, nucleus, ER, plasmodesma, and extracellular region. Studies of related genes in other species link the family to salt tolerance, superoxide detoxification, and fungal disease resistance.
