Traditional control methods for postharvest diseases rely on fungicides, which cause human health and environmental concerns. This study introduces a taxonomy-guided strategy for selecting biocontrol agents. By focusing on group, which harbors diverse plant-beneficial strains, the inadvertent selection of harmful strains was circumvented, thereby obviating the need for laborious screening assays. A highly promising candidate, strain P39, has been identified, exhibiting remarkable biocontrol activity against . Through comprehensive genomic, physiological, and biochemical analyses, P39 was characterized as a novel species within the genus and designated . Moreover, these findings deepen our understanding of bacterial-fungal interactions, as they elucidate a potential pathway for the utilization of fungal chitin, thereby enhancing our understanding of bacterial mycophagy. is a promising source of antifungal volatiles and putative novel secondary metabolites.
传统的采后病害防治方法依赖于杀菌剂，这引起了人类健康和环境方面的关注。本研究介绍了一种基于分类群指导的生物防治剂选择策略。通过关注含有多种植物有益菌株的组，避免了有害菌株的意外选择，从而无需进行繁琐的筛选试验。已经确定了一个很有前途的候选菌株 P39，它对表现出显著的生防活性。通过全面的基因组、生理和生化分析，P39被鉴定为属内的一个新种，并命名为。此外，这些发现加深了我们对细菌-真菌相互作用的理解，因为它们阐明了利用真菌几丁质的潜在途径，从而增强了我们对细菌食真菌的理解。是一种有前途的抗真菌挥发物和潜在新型次生代谢物的来源。
