sod — Cicer arietinum

Summary

LOC105851841 (symbol sod) on chickpea chromosome 3 encodes a copper‑zinc superoxide dismutase, confirmed by its superoxide dismutase activity, copper‑binding capacity, and the presence of a SOD_Cu_Zn domain. The gene is associated with a wide range of biological processes, including the ascorbate‑glutathione cycle, cellular responses to ozone, UV‑B, and light intensity, as well as polyamine metabolism, protein oxidation, and cellular respiration. It is linked to numerous agronomically important traits such as grain yield per plant, grain size, biomass yield, leaf chlorophyll content, net photosynthetic rate, canopy temperature, days to maturity, and root and shoot dry weights. Additional associations include lycopene, carotenoid, flavonoid, proline, and hydrogen peroxide content, as well as flower abortion and leaf relative water content. The encoded protein localises to the cytoplasm. Studies of related genes in other species connect the family to seed viability.
