As our understanding of the human microbiome progresses, so does the need for natural
experimental animal models that promote a mechanistic understanding of beneficial …

Microorganisms shape, and are shaped by, their environment. In host–microbe associations,
this environment is defined by tissue chemistry, which reflects local and organism-wide …

Most terrestrial plants, including crops, engage in beneficial interactions with arbuscular
mycorrhizal fungi. Vital to the association is mutual recognition involving the release of …

Outer membrane vesicles (OMVs) are continuously produced by Gram-negative bacteria
and are increasingly recognized as ubiquitous mediators of bacterial physiology. In …

Host immune and physical barriers protect against pathogens but also impede the
establishment of essential symbiotic partnerships. To reveal mechanisms by which …

Genome erosion is a frequently observed result of relaxed selection in insect nutritional
symbionts, but it has rarely been studied in defensive mutualisms. Solitary beewolf wasps …

The marine bacterium Vibrio fischeri is the monospecific symbiont of the Hawaiian bobtail
squid, Euprymna scolopes, and the establishment of this association involves a number of …

Availability and efficient utilization of host-derived nutrients by pathogens decide the fate of
host-pathogen interaction. In Magnaporthe oryzae, N-acetylglucosamine (GlcNAc) catabolic …

Many proteobacteria modulate a suite of catabolic genes using the second messenger cyclic
3′, 5′-AMP (cAMP) and the cAMP receptor protein (CRP). Together, the cAMP-CRP …

Acetylation is a broadly conserved mechanism of covalently modifying the proteome to
precisely control protein activity. In bacteria, central metabolic enzymes and regulatory …
