title: Evolution of parasitic symbioses between plants and filamentous microorganisms.
abstract: Innate defense in wild plant populations is an invaluable resource for understanding how sustainable disease control can be achieved in crops through research that is rooted in molecular and evolutionary biology. Much progress has been made from molecular research into pathogen detection and defense induction. Bacterial pathology of the wild species Arabidopsis thaliana is at the forefront in revealing parallels with animal innate immunity against infectious diseases. In plants, unlike in animals, however, expansion in biodiversity has been mirrored by tremendous diversification in filamentous parasites. The fungal and oomycete pathology of Arabidopsis is exposing opportunities to investigate the molecular bases of compatibility, plant-driven speciation of parasites, and molecular epidemiology. Such research might reveal evidence that an arms race did occur in the evolution of plant-parasite symbioses.
