Plant defense against microorganisms consists of a variety of preformed barriers and dynamic responses. Numerous secondary metabolites are present in sufficient concentrations to be toxic and useful as chemical barriers. Structural materials, such as the cuticle and cell walls, are effective as physical barriers to invasion. Preformed barriers require no plant response to be effective deterrents to colonization by microorganisms. Plants can, however, also respond defensively to the presence of some microorganisms. These active responses encompass a complex of strategies to minimize the impact of the invading microorganism. But, active defenses must be triggered to be effective.
