Nonhost resistance to Phytophthora: novel prospects for a classical problem.
Members of the oomycete genus Phytophthora are the most devastating pathogens of dicot plants. Recent developments in the study of these organisms have led to improved understanding of their phylogenetic relationships and trends in their evolution. Molecular analyses of nonhost (species-level) resistance offer exciting prospects for disease management. A model that evokes a complex interplay of several layers of specific resistance, mediated by a set of ancient broad-spectrum R-gene loci, is sufficient to explain existing cellular and molecular data on nonhost resistance to Phytophthora.
