Genetic diversity of Pseudomonas solanacearum detection of restriction fragment lenght polymorphisms with DNA probes that specify virulence and the hypersensitive response
Soluble peroxidase in fluid from the intercellular spaces of tobacco leaves.
Specific activity data suggest that an active process is responsible for the transfer of soluble peroxidase to the inter cellular space and that the intercellular fluid fraction is not simply composed of material moving out of leaf cells by diffusion. Expand
Increases in peroxidase activities are not directly involved in induced resistance in tobacco
It was concluded that peroxidase increases are not directly involved in disease resistance, and probably result from injury caused by toxic compounds in the bacterial cell suspension. Expand
Lipopolysaccharide-Defective Mutants of the Wilt Pathogen Pseudomonas solanacearum
The hypothesis that differences in LPS structure are associated with the ability or inability of different strains to induce a hypersensitive response in tobacco was tested but the evidence did not support the hypothesis that the initial interaction between rough LPS and tobacco cell walls is the determining factor in HR initiation.

Production of EPS appears to be essential for virulence; EPS may prevent agglutination of bacteria in the host, thus allowing their multiplication. Expand
