Abstract

The majority of plants are highly resistant to attack by most micro-organisms (non-host or species resistance). The number of true host/ pathogen combinations is comparatively small, but these interactions cause signifieant losses in agriculture. Within a susceptible plant species, resistance may be expressed in a number of host cultivars to certain races of a pathogen (cultivar resistance). The biochemieal mechanisms of non-host resistance and cultivar resistance are similar and include a wide range of inducible defense responses. Many of these responses involve gene activation (e.g., the phytoalexin response), whereas others do not (e.g., callose formation). Compatible plant/pathogen combinations are characterized by a de1ay or apparent absence of the typical defense response, which may be caused by pathogen-mediated disturbances at any level of the reaction sequence(s) leading to successful resistance.
