RabE- and RabA-mediated trafficking define two functionally distinct branches of plant pre-invasive immunity, with RabE specifically supporting powdery mildew defense and RabA broader oomycete-linked defense.
- Why it matters: Pre-invasive immunity relies on membrane trafficking, but the specific trafficking routes that tailor defenses to different pathogens are not well understood.
- What they did: They inhibited RabE and RabA GTPase subfamilies and measured immunity to powdery mildew fungi (including mlo durable immunity) versus Phytophthora infestans, alongside PEN1 focal accumulation and callose deposition.
- The result: RabE inhibition rapidly compromised powdery mildew immunity and reduced PEN1 accumulation at papillae without substantially affecting callose, whereas RabA inhibition disrupted plasma membrane localization of multiple proteins and preferentially compromised Phytophthora infestans immunity.
