Abstract
Fungi are eukaryotic, carbon-heterotrophic microorganisms most of which are living saprophytically by degrading dead organic material. However, a small minority of them have acquired the capability to recruit nutrients from living plants, thereby usually causing disease in the host. However, plants are far from being the unprotected prey of any potential pathogen. Instead, they successfully ward off most offenders through the utilization of a large array of passive and active defense mechanisms. Hence, fungal pathogenicity and high virulence, the extreme form of which has become apparent in several devastating epidemics of crop plants, require the interplay of a number of factors and processes on both the fungal and the plant side. Over the years, many review articles have covered the manifold plant resistance reactions (Alexander et al., 1994; Bowles, 1990; Kombrink and Somssich, 1995; Lamb, 1994; Tzeng and DeVray, 1993), so that this topic will be dealt with only briefly in the present chapter. Instead, molecular aspects of fungal pathogenicity and virulence will be illustrated using a number of selected examples. In addition, recent results on the mechanisms of genetically defined resistance of plants will be described that may allow the development of a general concept of the plant defense system.
