With the exception of Phytophthora parasitica var. nicotianae (Ppn), the tobacco black-shank causing agent, Phytophthoras give rise to non-host interactions with tobacco. The resulting local hypersensitive response (HR) is accompanied by necrotic spots on the leaves at distance from the infection site [1]. Low molecular weight proteins are excreted by these Phytophthoras, both in planta and in vitro. They form a family of highly homologous holoproteins, called elicitins [2]. Tobacco plants treated with purified elicitins develop necrotic symptoms similar to those induced by the live fungus, and become resistant to further inoculation with Ppn [3]. Elicitin-treated tobacco represent an attractive model for the analysis of HR and its relation to acquired resistance.
