Cryptogein treatment stimulates clathrin-endocytosis correlated with ROS production in tobacco cells

2007

International audience; During plant pathogen interactions, specific molecules elicit defense response of plant cells. Cryptogein, an elicitin produced by the pathogenic fungus Phytophtora cryptogea, induces a hypersensitive response (HR) in tobacco plants. The mode of action for cryptogein starts with recognition of this elicitor by an unidentified plasma membrane (PM) receptor. This ligand-receptor binding trigger a cascade of events at the PM level including rapid calcium influx, ions effluxes, extracellular medium alcalinization and plasma membrane depolarization both in tobacco plants and suspension cells. These events lead to the activation of plasma membrane-bound NADPH oxidase, Ntrb…
