SOD — Pisum sativum

Summary

PSAT3G008560 (symbol SOD, preferred name SODCC) on garden pea chromosome 3LG5 encodes a copper‑zinc superoxide dismutase (EC 1.15.1.1) with superoxide dismutase activity and copper binding, localised to the cytoplasm. The gene is associated with cellular responses to ozone, light intensity, UV‑B, and salinity, as well as removal of superoxide radicals and reactive oxygen species homeostasis. It is linked to root gravitropism, root angle formation, and recognition of fungal and bacterial pathogens. Annotated associations include seed viability, photosynthetic rate, and the SALTTL trait. Studies of related superoxide dismutase genes in other species connect the family to grain yield, grain size, biomass yield, leaf chlorophyll content, water use efficiency, and stress‑related traits such as hydrogen peroxide, proline, and carotenoid content.
