Microbial interactions within the metaorganism: mechanisms of bacterial niche specialization and warfare in symbiosis

Project B4 (PIs Dagan, Unterweger) aims to investigate the mechanisms of bacterial niche specialization, focusing on interactions with the host and competitive interactions within the host-associated microbiome. This includes identifying the currencies at the origin of symbiosis, with a focus on symbiosis plasmids, as well as mechanisms of competitive interactions within the microbiome via T6SS- or bacteriocin-mediated killing.
