CCS (TRAESCS2D02G396500) — triticum aestivum

Summary

TRAESCS2D02G396500 (TaCCS) on wheat chromosome 2D encodes a copper chaperone for superoxide dismutase, containing a copper/zinc superoxide dismutase domain and a heavy-metal-associated domain. The gene product has superoxide dismutase copper carrier activity, binds copper, and is associated with superoxide metabolism, cellular copper ion homeostasis, glutathione and polyamine anabolism, and responses to ozone, UV-B, light intensity, salinity, and cadmium stress. TaCCS is linked to drought and heat tolerance, stripe rust resistance, photosynthetic rate, chlorophyll content, shoot dry weight, and phosphorus concentration. It localises to the chloroplast stroma and cytoplasm. Studies of related genes in other species connect the family to superoxide dismutase activity, copper homeostasis, and traits including rooting depth, leaf relative water content, plant height, and seed germination.
