NAC — Capsicum annuum

Summary

CaNAC (T459_12184) on pepper chromosome 4 encodes a NAC domain-containing transcription activator with DNA-binding and protein homodimerization activity. It is associated with diverse biological processes including carotenoid and capsorubin metabolism, chlorophyll breakdown, abscisic acid anabolism, pigment accumulation, leaf senescence, root hair elongation, and responses to salinity and other stimuli. The gene is linked to traits such as fruit size, leaf size, chlorophyll and carotenoid content, germination rate, photosynthetic rate, ethylene sensitivity, lignin content, proline content, disease tolerance, and brassinosteroid content. It localizes to the nucleus and cytoplasm. Studies of related genes in other species connect the family to drought tolerance, pathogen resistance, salt stress sensitivity, thermomemory, and abscisic acid and jasmonic acid signalling.
