This study follows on from a previous showing that binary mixtures of wheat cultivars affect the evolution Zymoseptoria tritici populations within field epidemic beginning (t1) to end (t2) growing season. Here, we focused impact interseason sexual reproduction this evolution. We studied susceptible and resistant (carrying Stb16q, recently broken-down resistance gene) in proportions 0.25, 0.5 0....

The speciation of pathogens can be driven by divergent host specialization. Specialization to a new host is possible via the acquisition of advantageous mutations fixed by positive selection. Comparative genome analyses of closely related species allows for the identification of such key substitutions via inference of genome-wide signatures of positive selection. We previously used a comparativ...

BACKGROUND The development of novel highly efficacious fungicides that lack cross-resistance is extremely desirable. Fenpicoxamid (Inatreq™ active) possesses these characteristics and is a member of a novel picolinamide class of fungicides derived from the antifungal natural product UK-2A. RESULTS Fenpicoxamid strongly inhibited in vitro growth of several ascomycete fungi, including Zymosepto...
