  Soil salinization severely threatens crop productivity. We previously revealed that ethanol treatment enhances abiotic stress tolerance, including salt stress, in plants. Ethanol up-regulated the transcription and activity of ascorbate peroxidase (APX1/2), key ROS detoxifing enzymes, thereby reducing ROS accumulation and improving salt stress tolerance. However, the transcriptional regulation underlying ethanol-mediated stress tolerance remains unclear. In this study, we identified Telomere repeat binding (TRB) proteins as transcription factors involved in ethanol-mediated salt stress tolerance. Transcriptome analysis revealed that copper/zinc superoxide dismutase (CSD) genes were down-regulated in TRB3-SRDX mutant. We further demonstrated that SOD activity was reduced in trb1/2/3 mutantm and csd mutant showed salt stress sensitivity even presence with ethanol, indicating that CSD are essential for ethanol-mediated salt stress tolerance. ChIP assays confirmed that TRB3 directly binds to CSD genes. Furthermore, ethanol treatment promoted H4K5 acetylation at CSD loci. These findings suggests that ethanol metabolism contributes to histone acetylation, and TRB3 facilitates its deposition at CSD loci, leading to enhanced CSD activation and improved salt stress tolerance.
