Prevention of hypersensitive confluent‐necrosis in tobacco mesophyll, caused by Pseudomonas syringae pv. aptata , and tolerance towards the incompatible bacterium are induced 48 h after intercellular injection of protein‐lipopolysaccharide complexes. Histochemical analysis and ultrastructural observations were carried out to determine whether there was an association between this tolerance state and cell wall alterations due to callose, lignin and/or suberin deposition either before or after challenge with the incompatible bacterium. No evidence was obtained for such wall alterations.
