摘要： Ralstonia solanacearum can induce severe wilt disease in vital crops. Therefore, there is an urgent need to develop novel antifungal solutions. The natural compound 2,4-di-tert-butylphenol (2,4-DTBP) exhibits diverse physiological activities and affects soil function. However, its specific impact on the R. solanacearum remains unclear. Here, we investigated the antimicrobial potential of 2,4-DTBP. The results demonstrated that 2,4-DTBP effectively inhibited its growth and altered morphology. In addition, it substantially impeded biofilm formation, motility, and exopolysaccharide secretion. Transcriptomic analysis revealed that 2,4-DTBP inhibited energy production and membrane transport. Additionally, 2,4-DTBP hindered the growth by interfering with the membrane permeability, reactive oxygen species (ROS) production, and electrolyte leakage. Concomitantly, this led to a significant reduction in pathogenicity, as evidenced by the biomass of R. solanacearum in the invaded roots. Overall, our data strongly support the potential utility of 2,4-DTBP as a potent antibacterial agent capable of effectively preventing the onset of bacterial wilt caused by R. solanacearum.
