| Outline of Final Research Achievements |
Tolnifanide is an antifungal agent with sulfonamide structure, which inhibits mycelial growth of Pleosporales fungi including Bipolaris spp. For understanding its mode of the action, we developed tolnifanide-resistant mutants of Bipolaris maydis by chemical mutagenesis and characterized them, genetically. By crossings, two mutant genes (Tfr1, Tfr2) were identified. Comparisons of whole genomes from the wild type and the resistant offsprings revealed TFR1 and TFR2 encode geranylgeranyl transferase and farnesyl diphosphate farnesyl transferase, respectively. We also revealed that polyoxin-resistant genes POL2 and POL4 encode ferrochelatase and porphobilinogen deaminase, respectively.
