|a Abiotic stress seriously affects the growth, yield, and fiber quality of cotton. It is of great importance to cultivate drought-resistant and salt-tolerant cotton. NAC (NAM, ATAF1/2, and CUC2) is a plant-specific transcription factor, which is widely involved in the response to abiotic stress. Here, we discovered the GhNAC3 gene isolated from the expression profile of drought stress in cotton and verified its functions in cotton. First, GhNAC3 was strongly induced expression by drought and salt stresses. Gene structure analysis revealed that GhNAC3 had a conserved NAC domain and was homologous to several stress-related NAC transcription factors gene of Arabidopsis. Subcellular localization and transcriptional activation assays revealed that GhNAC3 was a nuclear protein with a C-terminal transcriptional activation domain. Overexpression of GhNAC3 enhanced Arabidopsis tolerance to drought stress with reduced sensitivity to ABA, characterized by increased germination and cotyledon rates under drought stress, and promoted root elongation. VIGS silencing of GhNAC3 reduced cotton tolerance to drought stress as indicated by the low water content of the leaves under drought treatment, significantly faster water loss and lower ABA content in detached leaves, along with the accumulation of more hydrogen peroxide (H2O2) and malondialdehyde (MDA). In conclusion, GhNAC3 plays an important role in the abiotic stress of cotton, which might have great application potential in molecular breeding of cotton varieties with drought resistance
