COVER An Arabidopsis thaliana seedling with downy mildew disease, caused by the oomycete pathogen Hyaloperonospora arabidopsidis. Four Reports beginning on page 1540 present comparative genomic analyses of several plant pathogens that shed light on their biology, including their virulence, dependence upon their host, and host specifi city. Included are pathogens responsible for economically devastating diseases in crop plants. Also see the related Perspective on page 1486.
