Microbial pathogen suppression operates through two primary mechanisms. The first involves direct antagonism, where beneficial microbes parasitize or compete with pathogens for resources, produce antimicrobials, or disrupt quorum sensing. The second mechanism involves the indirect suppression of pathogens via priming or Induced Systemic Resistance (ISR) in the host plant. During ISR, non-pathogenic microbes trigger plant immune responses, modulating hormonal signaling and enhancing pathogen resistance. These mechanisms are highly interconnected and influenced by external conditions such as soil composition, microbial activity, and community structure. Microbial consortia may interact synergistically to suppress plant diseases through collective effects within the plant-microbiomeenvironment system (Maciag et al., 2023).Microbiome manipulation to suppress pathogens is an under-explored strategy to improve crop health and yield. There is an urgent need for sustainable disease management solutions, intensified by pathogen-resistance acceleration and even more by climate change. This Research Topic compiles studies examining the ecological, physiological, molecular, and functional aspects of pathogen suppression by plant microbiota, with a focus on symbiotic interactions.The six articles provide valuable methodological approaches and insights into how the plant microbiota contributes to pathogen suppression (Figure 1). Comparative microbiome analyses reveal how microbial diversit...
