BACKGROUNDCrops are consistently under siege by a multitude of pathogens. These pathogenic microorganisms, including viruses and bacteria, result in substantial reductions in quality and yield globally by inducing detrimental crop diseases, thus posing a significant challenge to global food security. However, the biological activity sepectrum of commercially available pesticides is limited and the pesticide efficacy is poor, necessitating the urgent development of broad‐spectrum and efficient strategies for crop disease prevention and control.RESULTSThe bioassay results revealed that certain target compounds demonstrated outstanding in vivo antiviral efficacy against cucumber mosaic virus and tobacco mosaic virus. In particular, compound D6 showed remarkable antiviral activity against CMV, significantly higher than that of the control agent ningnanmycin. Mechanism of action studies have shown that compound D6 could enhance the activity of defense enzymes and upregulate the expression of genes related to disease resistance, thereby enhancing the antiviral effects in plants. In addition, these compounds displayed superior inhibitory activity against plant bacterial diseases. For Xoo, compound D10 showed an excellent inhibitory effect that was better than that of the control agent bismerthiazol. Scanning electron microscopy and fluorescence double‐staining experiments revealed that compound D10 effectively inhibited bacterial growth by disrupting the cell membrane.CONCLUSIONA series of trifluoromethyl hydrazone derivatives were designed and synthesized, and it was found that they have control effects on plant viruses and bacterial diseases. In addition, this study revealed the mechanism of action of the active compounds and demonstrated their potential as multifunctional crop protectants. © 2024 Society of Chemical Industry.

Militarine is a monomer molecule with abundant and distinctive biological properties, also the lead member of secondary metabolites in Bletilla striata, while its biosynthesis mechanism is still unknown. To improve the production efficiency of militarine, sodium acetate and salicylic acid (SA) were introduced as elicitors into the suspension-cultured callus of B. striata. Subsequently, samples were taken from callus at different culturing stages to investigate the synthesis mechanisms of militarine in B. striata through integrated metabolomics and transcriptomics. Metabolomics analysis revealed that acetate ions promoted militarine synthesis, while SA had an inhibitory effect. Additionally, regulators such as ferulic acid, 2-hydroxy-3-phenylpropionic acid, and cis-beta-D-Glucosyl-2-hydroxycinnamate were identified as influencing militarine synthesis. Transcriptomics analysis indicated that the expression levels of genes involved in phenylalanine metabolism, phenylpropanoid biosynthesis, and tyrosine metabolism were correlated with militarine content. This study sheds light on the regulatory mechanism of militarine biosynthesis in plants. The results suggested that acetate ions and SA impact militarine synthesis through specific metabolic pathways and gene expression changes. This knowledge serves as a foundation for future research on militarine biosynthesis and its industrial production.
