CCS (TRAESCS2A02G399000) — triticum aestivum

Summary

TRAESCS2A02G399000 (TaCCS) on wheat chromosome 2A encodes a superoxide dismutase copper chaperone, a protein with a copper/zinc superoxide dismutase domain and a heavy-metal-associated domain. It possesses superoxide dismutase copper carrier activity and copper binding, and is associated with superoxide metabolism, cellular copper ion homeostasis, and responses to ozone, UV-B, light intensity, and salinity. TaCCS is linked to glutathione and polyamine anabolism, removal of superoxide radicals, cadmium transport, and fatty acid metabolism. It localises to the chloroplast stroma and cytoplasm. The gene has been connected to grain yield, grain size and weight, heading time, anthesis time, plant height, shoot dry weight, chlorophyll content, photosynthetic rate, heat tolerance, drought tolerance, stripe rust resistance, and phosphorus concentration. Related genes in other species link the family to copper homeostasis and superoxide dismutase activity.
