Ethanol-enhanced salt stress tolerance in Arabidopsis thaliana seedlings depends on TRB proteins that regulate Cu/ZnSOD genes, with ethanol boosting Cu/ZnSOD activity.
- Why it matters: Soil salinization threatens crop productivity, and while ethanol is known to improve salt tolerance via ROS detoxification, the broader transcriptional regulators and mechanisms were unclear.
- What they did: The study used transcriptome profiling and qRT-PCR to link TRB proteins to AtCSD1, AtCSD2, and AtCCS expression, then tested mutants (csd1 and ccs) for salt sensitivity and superoxide accumulation after ethanol treatment.
- The result: ChIP showed AtTRB3 associates with AtCSD1/AtCSD2/AtCCS and that ethanol increases H4K5 acetylation at these loci, implying TRB-driven chromatin activation supports Cu/ZnSOD-mediated ROS detoxification.
