Mutualist-pathogen co-colonisation modulates phosphoinositide signatures at host intracellular interfaces

Caption

Mutualist-pathogen co-colonisation modulates phosphoinositide signatures at host intracellular interfaces: Nicotiana benthamiana plants expressing biosensors for PI4P and PI(4,5)P2. PI(4,5)P2 was tip-enriched at mutualist structures but evenly distributed around pathogen structures. PI4P was absent from pathogen extrahaustorial membranes but present at invasive hyphae and mutualist interfaces. Co-colonisation triggered PI4P recruitment at pathogen haustoria, and enhanced resistance to P. palmivora.
