A Rab GTPase-Activating Protein Links Secondary Metabolism and Virulence in the Nematophagous Fungus Purpureocillium lavendulum.

Key Points

• The research aims to explore the relationship between secondary metabolism and virulence in the fungus Purpureocillium lavendulum.
• Conducted pot experiments to evaluate enzyme secretion and metabolic pathways in the fungus.
• Identified PlGyp1 as a key protein involved in vesicular trafficking.
• PlGyp1 was found to be a central hub influencing enzyme secretion and secondary metabolism.
• The findings support the potential of PlGyp1 for genetic enhancement in biocontrol applications.
