Research highlight: The Fusarium oxysporum Avr2-Six5 effector pair alters plasmodesmatal exclusion selectivity
Pathogens use effector proteins to manipulate their hosts. During infection of tomato the fungus Fusarium oxysporum secretes the effectors Avr2 and Six5. Whereas Avr2 suffices to trigger I-2-mediated cell death in heterologous systems, both effectors are required for I-2-mediated disease …
