Site‐directed mutagenesis of the cytochrome <i>b</i> gene and development of diagnostic methods for identifying QoI resistance of rice blast fungus

Abstract

As the management of rice blast disease is often dependent on chemicals, the rational design of control programmes requires a proper understanding of the fungicide resistance phenomenon in field populations of the pathogen. Mutation of the cytochrome b gene of rice blast fungus would be specifically detected from diseased leaves and seeds using the molecular methods developed in this study.
