NADPH oxidase enzymes encoded by the Rboh gene could cause the accumulation of ROS, which is critical in the defense system of plants, because it can inhibit the pathogens infection process by directly inhibiting pathogen or inducing hypersensitivity at the infection site (Torres and Dangl, 2005; Lehmann et al., 2015; Camejo et al., 2016; Segal and Wilson, 2018). This evidence concerns the gene FMO5 and infection.
