CCS — Capsicum annuum

Summary

T459_00432 (CCS, CaCCS) on pepper chromosome 1 encodes a superoxide dismutase copper chaperone, possessing superoxide dismutase copper carrier activity and copper binding, and belongs to the SOD_Cu/Zn/chaperone and HMA domain families. The gene is associated with capsanthin and capsorubin anabolism, carotene and carotenoid anabolism and metabolism, pigmentation, fruit ripening, cellular responses to ozone, light intensity, UV-B and salinity, removal of superoxide radicals, cellular copper ion homeostasis, virus-induced post-transcriptional gene silencing, and stomatal movement. Its product localises to the chloroplast stroma, membrane and cytoplasm. The gene is linked to carotenoid content, fruit size and colour, thermotolerance, arsenate stress response, and compromised bacterial resistance. Studies of related genes in other species connect the family to copper homeostasis and superoxide dismutase activity.
