Does Tssh Deletion In Paraburkholderia Bonniea Affect Its Symbiosis With Dictyostellum Discoideum?, Anna Chen
Honors Theses
Paraburkholderia are amoeba resistant, gram negative bacteria that form facultative symbiotic relationships with D. discoideum, a soil dwelling amoeba host. Three species of Paraburkholderia, P. agricolaris, P. hayleyella, and P. bonniea are able to persistently infect nonnative, or symbiont free, D. discoideum. These three species share a type III secretion system (T3SS) and type VI secretion system (T6SS) that is absent in other close relatives We hypothesized that the ability to persistently infect D. discoideum may be partially attributed to the T3SS and T6SS shared across the three species of Paraburkholderia.
The goal was to test the phenotypic effect of …
