Plants have developed efficient mechanisms to defend themselves against pathogen attack. Beside a number of preformed barriers they have a whole set of inducible defense reactions at their disposal, which appear to be similar in many diverse plant species and are used against different pathogens in non- host- and host-incompatible interactions (Hahlbrock and Scheel 1987). The induction of these responses requires recognition of the pathogen and consequent signal transduction. Both processes are difficult to study in the intact plant, since successful resistance reactions are usually limited to a few cells. In many plants, however, a typical resistance response is synchronously induced by treatment of cultured cells with plant- or pathogen-derived elicitors (DiCosmo and Misawa 1985). Some of these systems have been used with great success to elucidate the biochemistry and molecular biology of many plant defense responses and therefore represent excellent tools for studies on the mode of elicitor action (Ebel 1986; Hahlbrock and Scheel 1989).
