The global challenges of food security and sustainable agriculture necessitate innovative approaches to crop protection. This project investigates the intriguing interkingdom signaling mechanisms between beneficial bacteria (Bacillus subtilis species complex) and a devastating fungal pathogen (Sporisorium scitamineum) that causes sugarcane smut disease. While bacterial lipopeptides are known for their antimicrobial properties, their potential roles as signaling molecules at sub-inhibitory concentrations remain largely unexplored, especially for basidiomycete plant pathogens.

This research aims to unravel how lipopeptides (iturin A, fengycins, and surfactins) impact S. scitamineum's growth, morphology, mating, and virulence in sugarcane. We will characterize lipopeptide effects at various concentrations, investigate their impact on fungal virulence, elucidate underlying molecular mechanisms, and explore their ecological relevance in soil and on plant surfaces.

By bridging fundamental research with practical applications, this project has the potential to revolutionize our understanding of microbial ecology in agricultural systems. The findings may lead to novel, eco-friendly biocontrol strategies, contributing significantly to sustainable agriculture and global food security. This timely research aligns with EU priorities and UN Sustainable Development Goals, promising substantial scientific, economic, and societal impacts.
