2CPA — Daucus carota subsp. sativus

Summary

DCAR_023383 (symbol 2CPA, also known as Dc2CPA, DcPER1, PER1, REHY, Dc2-CYS-PRX-B, 2-CYS-PRX-B, BAS1, 2CPB, Dc2CPB, DcBAS1) on carrot chromosome 7 encodes a thioredoxin-dependent peroxiredoxin with multiple additional annotated molecular functions including carbonic anhydrase, glutamate synthase, and linoleate 13S-lipoxygenase activities, as well as salicylic acid binding and autophagy adaptor activity. The product belongs to the peroxiredoxin AhpC/TSA family and contains thioredoxin and peroxiredoxin domains. In carrot, 2CPA is associated with brassinosteroid breakdown, maintenance of seed dormancy, cellular oxidant detoxification, negative regulation of stomatal complex development and the reductive pentose-phosphate cycle, response to carbon dioxide, regulation of chlorophyll biosynthesis and leaf morphogenesis, and protein targeting to vacuole during autophagy. It localizes to the thylakoid lumen, chloroplast thylakoid membrane, stromule, and proteasome. The gene is linked to numerous agronomic traits including photosynthetic ability, biomass yield, seed yield, leaf shape, rolled leaf, stem senescence, herbicide sensitivity, viral disease response, aphid response, jasmonic acid sensitivity and content, UV-B light sensitivity, copper and zinc sensitivity, and pollen fertility restoration
