The Fungal Biorevolution: A Trifecta of Genome Mining, Synthetic Biology, and RNAi for Next-Generation Fungicides

Modern agriculture faces a critical challenge from escalating fungicide resistance and the ecological impact of conventional agrochemicals. A paradigm shift is required, moving beyond simple product substitution toward an integrated technological platform. This review outlines such a platform, built on the synergy of three technologies: genome mining for rational discovery of novel antifungal compounds, synthetic biology for their scalable and cost-effective production, and RNA interference (RNAi) for highly specific pathogen control and resistance management. We argue that the integration of this trifecta—discovery, production, and targeted application—creates an adaptable pipeline for developing next-generation biofungicides. This approach transforms crop protection from a static defense to a dynamic, sustainable system capable of co-evolving with pathogens, ensuring future food security while minimizing environmental impact.
