NAC — Daucus carota subsp. sativus

Summary

DCAR_017967, designated DcNAC, encodes a NAC domain-containing protein on carrot chromosome 5. The product is annotated with DNA-binding transcription activator activity and sequence-specific DNA binding, and localises to the nucleus and cytoplasm. In carrot, DcNAC is associated with regulation of root hair elongation, leaf senescence, photomorphogenesis, hypoxia and sucrose responses, heat acclimation, and glucosinolate metabolism. It is linked to brassinosteroid content, ethylene sensitivity, photosynthetic and respiration rates, seedling growth, root thickness, and disease tolerance. Related genes in other species are associated with drought tolerance, ABA sensitivity, thermomemory, pathogen resistance, bacterial resistance, and fruit ripening.
