In the search for new crop protection microbial biocontrol agents, isolates from the genus are commonly found with promising attributes. are natural soil dwellers and have evolved as plant symbionts producing specialised metabolites with antibiotic and antifungal activities. biocontrol strains can effectively suppress plant pathogens via direct antimicrobial activity, but also induce plant resistance through indirect biosynthetic pathways. The investigation of factors stimulating the production and release of bioactive compounds is commonly conducted , between sp. and a plant pathogen. However, recent research is starting to shed light on the behaviour of these biocontrol agents , where the biotic and abiotic conditions share little similarity to those of controlled laboratory conditions. With a focus on specialised metabolites, this review details (i) the various methods by which biocontrol agents employ specialised metabolites as an additional line of defence against plant pathogens, (ii) the signals shared in the tripartite system of plant, pathogen and biocontrol agent, and (iii) an outlook on new approaches to expedite the identification and ecological understanding of these metabolites under a crop protection lens.
在寻找新型作物保护微生物生物防治剂的过程中，通常会发现该属的分离物具有令人期待的特性。它们是天然的土壤栖息者，已进化成为植物共生体，能产生具有抗生素和抗真菌活性的特殊代谢产物。生物防治菌株可通过直接抗菌活性有效抑制植物病原体，还能通过间接生物合成途径诱导植物抗性。刺激生物活性化合物产生和释放的因素研究通常在该属某一物种与植物病原体之间进行。然而，最近的研究开始揭示这些生物防治剂在自然环境中的行为，其中生物和非生物条件与受控实验室条件几乎没有相似之处。本综述聚焦于特殊代谢产物，详细阐述了：（i）生物防治剂利用特殊代谢产物作为抵御植物病原体的额外防线的各种方法；（ii）植物、病原体和生物防治剂三方系统中共享的信号；（iii）从作物保护角度加快这些代谢产物鉴定和生态理解的新方法展望。
