Powdery mildew susceptibility and biotrophic infection strategies.
Plants are resistant to most potentially pathogenic microbes. This forces plant pathogens to develop sophisticated strategies to overcome basic plant resistance, either by masking intrusion or by suppression of host defences. This is particularly true for fungal pathogens, which establish long lasting interactions with living host tissue, without causing visible damage to invaded cells. The interactions of cereal crops and Arabidopsis with powdery mildew fungi are model systems for understanding host resistance. Currently, these systems are also promoting the understanding of fungal infection by identifying fungal pathogenicity and virulence factors and host target sites. This minireview focuses on recent findings about host susceptibility and the way powdery mildew fungi might induce it.
