Transcription activator that binds to the promoter of the stress response gene LEA19. Involved in tolerance to abiotic stresses (PubMed:20632034). Transcription activator involved in response to abiotic and biotic stresses. Involved in drought and salt stress responses, and defense response to the rice blast fungus (PubMed:17587305). Transcription activator involved tolerance to cold and salt stresses (PubMed:18273684). Transcription activator involved in tolerance to drought stress. Targets directly and activates genes involved in membrane modification, nicotianamine (NA) biosynthesis, glutathione relocation, accumulation of phosphoadenosine phosphosulfate and glycosylation in roots (PubMed:27892643). Controls root growth at early vegetative stage through chromatin modification and histone lysine deacytaltion by HDAC1 (PubMed:19453457). Interacts with NAC071. Widely expressed. Induced by drought stress, salt stress, cold stress and abscisic acid (ABA) (PubMed:20632034, PubMed:27892643). Induced by methyl jasmonate (PubMed:20632034, PubMed:11332734). Induced by infection with the rice blast fungus Magnaporthe oryzae (PubMed:11332734). The NAC domain includes a DNA binding domain and a dimerization domain. Increased root length in young seedlings. Plants overexpressing NAC048 exhibit growth retardation (PubMed:17587305, PubMed:20632034). Plants overexpressing NAC048 exhibit improved tolerance to drought stress (PubMed:17587305, PubMed:27892643). Plants overexpressing NAC048 show increased tolerance to salt stress (PubMed:17587305, PubMed:18273684). Plants overexpressing NAC048 exhibit increased tolerance to cold stress (PubMed:18273684). Plants overexpressing NAC048 show increased resistance to rice blast fungus (PubMed:17587305).
