Pseudomonas syringae pv. tomato
- infects Arabidopsis thaliana, Nicotiana benthamiana, and cause bacterial speck on tomato
- infects several Allium spp. and causes rotting diseases on onion
Bacterial pathogens are largely infect plants indirectly through wounds and natural openings. Infections can have devastating effects on a variety of crops. Some symptoms of various bacterial diseases include:
- Fruit/Leaf spots
- Soft rot
- Stem/Leaf Blight
The phytobacteriology course offered to graduate students, PATH 6290/L, teaches students about isolation, identification, inoculation, biology, and control of plant pathogenic bacteria. The lab portion will explore basic microbiological and molecular techniques to studying these pathogens.
Research in our lab focuses on understanding the mechanisms of plant immune action on bacteria. More specifically, we are interested in understanding how plant immunity effects the pathogenic bacteria. We hope to uncover the various processes by which plants restrict the colonization of phytobacteria. Our research aims to analyze the molecular plant-microbe interactions of various phytopathogenic bacteria. We use bacterial genetic and genomic engineering, transcriptome analyses, pathogenicity and host range assays to investigate these research objectives. Our lab also develops new genetic tools that can facilitate our research.
