CCS (TRAESCS2B02G417000) — triticum aestivum

Summary

TRAESCS2B02G417000 (TaCCS) on wheat chromosome 2B encodes a superoxide dismutase copper chaperone, a protein with copper-binding and superoxide dismutase copper carrier activity. The gene is associated with superoxide metabolism, cellular copper ion homeostasis, and glutathione and polyamine anabolism. It has been linked to chloroplast stroma localisation and to traits including grain size, grain weight, grain yield, plant height, heading time, anthesis time, photosynthetic rate, chlorophyll content, drought tolerance, salt tolerance, stripe rust, and phosphorus concentration. Associations with auxin content, seed development, and hormone signaling pathways have also been noted. Studies of related genes in other species connect the family to copper homeostasis and superoxide dismutase activity in multiple cellular compartments.
