We created a mutant in the MAP kinase-encoding Pmk1 gene of the rice blast fungus Magnaporthe oryzae (pmk1AS) that renders the gene sensitive to inhibition by 1NA-PP1. Fungal gene expression was compared during infection of rice sheath by the M. oryzae pmk1AS mutant in the presence and absence of 1NA-PP1. Overall design: Rice leaf sheaths inoculated with pmk1AS mutant of Magnaporthe oryzae with or without 1NA-PP1 (three independent biological replicates for each condition).
