Tailocins play a pivotal role in mediating microbial interactions among the economically significant plant pathogens within the <i>Pseudomonas syringae</i> species complex, with the potential to alter community structure and disease progression in host plants. Previous work looking at 45 <i>P.syringae</i> strains has demonstrated that at least two phylogenetic clades of tail fibers are encoded in the conserved tailocin region across the species complex, which roughly corresponds to two clusters of targeting activity. To better understand the full diversity of tail fibers associated with tailocins in the species complex, we screened 2161 publicly available genomes for their tailocin tail fiber content, predicted protein structures that represent the diversity of fibers, and investigated forces possibly driving the distribution of fibers throughout the species complex. Here we present evidence that, while the two previously described tail fiber clades are indeed widespread among virulent <i>P. syringae</i> strains, their distribution displays low congruency with phylogeny. Instead, we found that the presence of one tail fiber or the other is strongly correlated with the allelic diversity of another gene, associated with lipopolysaccharide O-antigen structure, dTDP-4-dehydrorhamnose reductase.

Despite the urgency of safeguarding these ecosystems, we know little about the ecological impacts of losing coral reef host-associated microbial communities (microbiomes). Here, we experimentally studied the microbiomes attached to or released from seven benthic reef hosts belonging to the functional groups of stony corals, soft corals, macroalgae, and sponges while manipulating the coral reef metacommunity to mimic biodiverse or degraded reef habitats. Developing an ecological framework, we found host species and functional groups to show distinct patterns of interacting with the environment (i.e. by exuding, maintaining, acquiring, or exchanging microbiome members), with habitat biodiversity primarily influencing microbial acquisition. In a degraded compared to a biodiverse habitat, the microbiomes of stony corals were less connected to soft corals and sponges, while those of soft corals, macroalgae, and sponges became more tightly linked. Our study demonstrates that a decline in metacommunity biodiversity is not merely associated with a proportional loss in microbial diversity; rather, it triggers complex changes in the microbial interactions among the persisting hosts with each other and the environment.
