Genomic insights into M. phaseolina: Multifactorial virulence via secreted effectors, carbohydrate enzymes and secondary metabolites.

Genomic analysis reveals that M. phaseolina possesses a highly diversified virulence arsenal, including 1070 extracellular proteins and 73 secondary metabolite gene clusters.

• Why it matters: Understanding the molecular basis of M. phaseolina's broad host range and virulence is crucial for developing effective disease management strategies, especially under climate change-driven stresses.
• What they did: De novo whole-genome sequencing and functional annotation identified 14,633 predicted protein-coding genes, with analyses highlighting secreted effectors, carbohydrate-degrading enzymes, and secondary metabolite pathways.
• The result: These insights provide a comprehensive genomic framework that advances host-pathogen interaction research and supports targeted approaches to control this pathogen's impact on over 500 plant species.
