Isolation and Characterization of Metabolites from Pseudomonas syringae-strain 3366 and their Phytotoxicity Against Certain Weed and Crop Species1
@article{Gealy1996IsolationAC, title={Isolation and Characterization of Metabolites from Pseudomonas syringae-strain 3366 and their Phytotoxicity Against Certain Weed and Crop Species1}, author={David R. Gealy and S. Gurusiddaiah and Alex G. Ogg}, journal={Weed Science}, year={1996}, volume={44}, pages={383-392} }
Phytotoxic effects of metabolites from a naturally occurring rhizobacterial isolate, Pseudomonas syringae strain 3366, were determined on downy brome and 'Hill 81' winter wheat, along with 10 other weed and crop species. Centrifuged supernatant and concentrated ethyl acetate extracts from aerobic shake cultures of strain 3366 suppressed germination of seeds and reduced root and shoot growth in agar diffusion assays, soil assays, and under fileld conditions. Generally, root growth was inhibited…

In steamed and natural soils, roots from which the antibiotic was recovered had significantly less disease than roots with no antibiotic, indicating that suppression of take-all is related directly to the presence of the antibiotic in the rhizosphere.

The results indicate that production of phenazine antibiotics by strains 2-79 and 30-84 can contribute to the ecological competence of these strains and that the reduced survival of the Phz- strains is due to a diminished ability to compete with the resident microflora.
