NAC — Capsicum annuum

Summary

CaNAC (T459_16867) on pepper chromosome 6 encodes a NAC-domain transcription factor with DNA-binding and transcription activator activity, localised to the nucleus and cytosol. 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 responses to salinity and other stimuli. It is linked to traits such as fruit size, leaf size, carotenoid and chlorophyll content, photosynthetic rate, germination rate, ethylene sensitivity, lignin content, proline content, disease tolerance, and brassinosteroid content. Studies of related genes in other species connect the family to drought tolerance, pathogen resistance, salt stress sensitivity, thermomemory, and jasmonic and salicylic acid signalling.
