Spotlight Articles Selected by the Editors of Plant Disease, Phytopathology, and Molecular Plant-Microbe Interactions (MPMI) Plant Disease Editor’s Pick Why does mefenoxam control grapevine downy mildew so effectively? In the October issue of Plant Disease, Megan Kennelly and co-authors report that in addition to mefenoxam’s systemic acroptetal movement, vapor activity of this fungicide enhances control on leaves and fruit clusters. Phytopathology Editor’s Pick In mixed infections, viruses identical except for expressing different fluorescent proteins, will infect different parts of the leaf and plant. No such spatial separation was observed in mixed infection of two different virus species (from different families) expressing these same fluorescent proteins. Thus, it was possible to visualize a viral turf war, where cross protection appears to be a key weapon. MPMI Editor’s Pick In the October issue of MPMI, Lee et al. show that WIN3 is an important component in the resistance of Arabidopsis to Pseudomonas syringae carrying avrRpt2. WIN3 acts downstream of RIN4 cleavage but upstream of the hypersensitive response and early SA accumulation. An online subscription is needed to access the full articles.
