NAC — Capsicum annuum

Summary

CaNAC (T459_14050) on pepper chromosome 5 encodes a NAC domain-containing protein 48 with DNA-binding transcription activator activity, sequence-specific DNA binding, and protein homodimerization activity. It localizes to the nucleus and cytoplasm. This gene is associated with diverse biological processes including carotenoid and capsorubin metabolism, chlorophyll breakdown, abscisic acid anabolism, pigment accumulation, leaf senescence, root hair elongation, and cell size control. It has been linked to traits such as fruit size, leaf size, chlorophyll content, carotenoid content, lignin content, proline content, photosynthetic rate, respiration rate, ethylene sensitivity, germination rate, and disease tolerance. Associations also include responses to oxidative stress, carbon and nitrogen metabolism, brassinosteroid content and catabolism, pathogen susceptibility, drought resistance, and salt tolerance. Studies of related genes in other species link the family to drought tolerance, ABA sensitivity, thermomemory, and pathogen resistance.
