英文摘要	NAC transcription factors play a pivotal role in plant growth, development and response to abiotic stress. However, their biological functions in desert trees are largely unknown. In this work, the NAC transcription factor HaNAC1 from Haloxylon ammodendron, a typical wooden plant normally grown in desert, was isolated, and its possible role in plant growth and resistance to drought stress was investigated. HaNAC1 encodes an ATAF subfamily transcription factor containing one NAC domain with five conserved regions. Quantitative real time PCR analyses revealed that HaNAC1 was ubiquitously expressed in various tissues and organs such as roots, stems, leaves and seeds, with a predominant expression in stems. Further studies demonstrated that expression of HaNAC1 was significantly induced by osmotic stress in Haloxylon ammodendron seedlings, and subcellular localization analysis indicated that GFP-HaNAC1 fusion protein was localized to the nucleus in Arabidopsis leaf protoplast. Ectopic expression of HaNAC1 led to promoted growth and drought tolerance in transgenic Arabidopsis, accompanied with up-regulated expression of stress-inducible marker genes, and increased accumulation of proline, IAA and ABA under both normal and drought stress conditions. In addition, co-immunoprecipitation and Bi-molecular fluorescence complementation assays illustrated that HaNAC1 directly interacted with AtNAC32. All these results suggest that HaNAC1 is involved in both the growth and drought resistance of Haloxylon ammodendron, and could be used as a promising candidate gene for the breeding of crops with augmented tolerance to drought stress.
