The cuticle and plant defense to pathogens

WebFeb 6, 2009 · For many fungi that infect plants, successful invasion is coupled to a series of differentiation steps that are necessary to breach the plant cuticle. Such fungi form specialized infection structures which allow direct penetration of the plant cuticle. WebIntroduction. Successful plant pathogens need to overcome preformed and activated defense barriers of their hosts for infection. To overcome such barriers at the cuticle and the cell wall, small wounds or penetration sites are created by invasive pathogens, using either disruptive enzymes or physical force or both (Hématy et al., 2009).The necrotrophic …
