A Survey of Plant Pathogenic Bacteria in the Great Smoky Mountain National Park
Lu S. 2016. A Survey of Plant Pathogenic Bacteria in the Great Smoky Mountain National Park
PI surveyed plant-associated bacteria present in the park. More than 50 plant samples with suspected bacterial disease symptoms were collected. Bacterial cell streaming was observed from 11 of the collected samples under microscope. Twenty-six bacterial isolates were obtained from the 11 plant samples. One isolate recovered from solomon's seal (Polygonatum sp.) is Erwinia billingiae, which was confirmed by DNA sequence analysis. E. billingiae is a plant pathogenic bacterium reported as a tree pathogen. Pseudomonas syringae pv. tomato, which is the tomato pathogen causing bacterial speck disease, was recovered from three locations and different plants. In addition, of the other 24 isolates, eight were the bacteria with diverse roles in nature, which including saprophytic and suppressive to plant pathogens.
