Fungi constitute a highly versatile group of eukaryotic carbonheterotrophic organisms that have successfully occupied most natural habitats. The vast majority of fungi are strict saprophytes; <10% of the *lOO,OOO known fungal sp-ecies are able to colonize plants, and an even smaller fraction of these are to a plant pathogen? Second, what mechanisms control the degree of virulence on the host once pathogenicity has been established?
