NAC — Nicotiana attenuata

Summary

A4A49_11037 (NaNAC) on chromosome 6 of coyote tobacco encodes a NAC domain-containing transcription factor with DNA-binding transcription activator activity. It is associated with diverse biological processes including secondary thickening, root hair elongation, dehiscence, pigmentation, jasmonic acid and zeatin anabolism, and viral genome replication. The gene is linked to traits such as leaf relative water content, chlorophyll content, photosynthetic and respiration rates, ethylene sensitivity, leaf senescence, root thickness, and disease tolerance. It has been connected to phenotypes including oxidative stress response, carbon and nitrogen metabolism, abiotic stress tolerance, brassinosteroid catabolism, pathogen susceptibility, and drought resistance. Studies of related genes in other species link the family to drought tolerance, thermomemory, ABA sensitivity, salt stress sensitivity, and resistance to bacterial pathogens.
