SOD — Capsicum annuum

Summary

CaSOD (T459_02925) on pepper chromosome 1 encodes a copper-zinc superoxide dismutase, an enzyme with superoxide dismutase activity (EC 1.15.1.1) that removes superoxide radicals and is associated with reactive oxygen species homeostasis. The gene is associated with cellular responses to oxidative stress, ozone, UV-B, light intensity, and copper, as well as heat dissipation, the ascorbate-glutathione cycle, and gene silencing by miRNA. Its product localises to the cytosol, nucleus, endoplasmic reticulum, plasmodesma, and extracellular region. CaSOD is linked to agronomically important traits including bacterial blight disease resistance, fruit size, plant height, chlorophyll content, net photosynthetic rate, root length and volume, canopy temperature, and the stay-green trait. It has also been connected to oxidative stress tolerance, thermotolerance, salt stress response, and copper homeostasis.
