Multiple hydrolases in bean leaves (Phaseolus vulgaris L.) and the effect of the halo blight disease caused by Pseudomonas phaseolicola (Burkh.) Dowson.
Multiple forms of hydrolytic enzymes were demonstrated in extracts of healthy bean leaves (Phascolus vulgaris L.) and bean leaves infected with the halo blight organism [Pseudomonas phaseolicola (Burkh.) Dowson] by polyacrylamide disc electrophoresis. Bean leaves contained up to 4 acid phosphatase bands, 9 esterase bands active towards alpha-naphthyl acetate, and 7 esterase bands towards alpha-...

متن کاملEarly changes in apoplast composition associated with defence and disease in interactions between Phaseolus vulgaris and the halo blight pathogen Pseudomonas syringae Pv. phaseolicola
The apoplast is the arena in which endophytic pathogens such as Pseudomonas syringae grow and interact with plant cells. Using metabolomic and ion analysis techniques, this study shows how the composition of Phaseolus vulgaris leaf apoplastic fluid changes during the first six hours of compatible and incompatible interactions with two strains of P. syringae pv. phaseolicola (Pph) that differ in...
متن کاملVolatile Products of the Lipoxygenase Pathway Evolved from Phaseolus vulgaris (L.) Leaves Inoculated with Pseudomonas syringae pv phaseolicola.
Activation of the "lipoxygenase pathway" in plants gives rise to a series of products derived from fatty acids. Analysis by gas chromatography-mass spectroscopy of volatile products produced by Phaseolus vulgaris (L.) cv Red Mexican leaves during a hypersensitive resistance response (HR) to the plant pathogenic bacterium Pseudomonas syringae pv phaseolicola showed evolution of several lipid-der...
متن کاملInvolvement of phaseolotoxin in halo blight of beans: transport and conversion to functional toxin.
Phaseolotoxin ([N(delta)-phosphosulfamyl]ornithylalanylhomoarginine) is produced by Pseudomonas phaseolicola (Burkh.) Dows. in liquid culture. When phaseolotoxin was applied to leaves of bean (Phaseolus vulgaris L.) at 0.1 to 1 nmoles/g fresh weight of leaf by a prick-assay procedure, the characteristic "halo" symptom of bean halo blight disease developed after 24 to 48 hours. At higher concent...
