2CPA — Daucus carota subsp. sativus

Summary

DCAR_031759 (Dc2CPA) encodes a protein with multiple annotated molecular functions, including TPx activity, carbonic anhydrase activity, linoleate 13S-lipoxygenase activity, thioredoxin reductase (NADPH) activity, and peroxidase activity, among others. The product localises to the chloroplast thylakoid lumen and thylakoid membrane. In carrot, Dc2CPA is associated with brassinosteroid breakdown, maintenance of seed dormancy, negative regulation of stomatal complex development, cellular oxidant detoxification, and regulation of chlorophyll biosynthesis and leaf morphogenesis. The gene is linked to numerous agronomic traits including photosynthetic ability, biomass yield, seed yield, rolled leaf, leaf shape, stem elongation, viral disease response, aphid response, herbicide sensitivity, and jasmonic acid sensitivity. Studies of related genes in other species connect the family to seed dormancy, abiotic stress tolerance (drought, salt, heat, cold, freezing), and resistance to fungal pathogens.
