A Novel ABC Transporter Gene ABC2 Involved in Multidrug Susceptibility but not Pathogenicity in Rice Blast Fungus, Magnaporthe grisea

Fungicide treatment is the most important method for the control of plant diseases caused by phytopathogenic fungi. But fungicide resistant strains have appeared in many phytopathogenic fungi. Until now, molecular mechanisms of fungicide resistance such as mutation of target protein, overproduction of target enzyme and detoxification of fungicide have been designated. Recently, it was demonstrated that active efflux of fungicides mediated by ATP-binding cassette (ABC) transporters also contributes to fungicide resistance in several filamentous fungi, such as Aspergillus nidulans, Penicillium digitatum and Botrytis cinerea.(중략)
