2CPA — Daucus carota subsp. sativus

Summary

DCAR_016922 (Dc2CPA) on carrot chromosome 5 encodes a thioredoxin-dependent peroxiredoxin (EC 1.11.1.24) with a peroxiredoxin_C domain and AhpC/TSA family signature. The product is associated with cellular oxidant detoxification, response to stress, and negative regulation of the reductive pentose-phosphate cycle and stomatal complex development. It is linked to brassinosteroid breakdown, maintenance of seed dormancy, and regulation of chlorophyll biosynthesis. The protein localises to the thylakoid lumen and chloroplast thylakoid membrane. Associations with agronomic traits include photosynthetic ability, biomass yield, seed yield, leaf growth and development, stem elongation, and responses to biotic stress, aphids, viral disease, UV-B light, copper, zinc, and jasmonic acid. Studies of related genes in other species connect the family to seed dormancy, germination under stress, and abiotic stress tolerance.
