A ‘reverse translation’ strategy using gnotobiotic mice ascertains cause and effect relationships between bacterial members of the gut microbiota, dietary components and host physiology, which are difficult to establish in human nutritional trials.
Prevotella copri, together with other microbiota members, plays a key role in mediating the beneficial effects of a gut microbiota-directed complementary food for malnourished children on microbiota and host functions.
A DNA barcoding approach enables discrimination between bacterial strains that could not be distinguished with conventional microbial marker gene amplicon sequencing techniques.
WISH-tags can be used in combination with quantitative polymerase chain reaction or next-generation sequencing to decipher population dynamics at the strain level within plant and mammalian microbiotas.
Characterizing bacterial responses to mixtures of chemical pollutants reveals interactive effects among pollutants. Our study highlights the predictability and resilience of microbial responses to complex mixtures of pollutants, offering the potential for improvements in ecotoxicological assessments.
Testing 255 combinations of chemicals versus bacterial communities shows species diversity contributes to resilience against increasingly complex stressor mixtures.
Cryogenic electron microscopy analysis of the Mycobacterium tuberculosis membrane-bound phosphoribosyltransferase Rv3806c provides mechanistic insight into cell wall precursor synthesis.
Single-molecule imaging reveals that peptidoglycan synthesis and synthase activity, rather than FtsZ treadmilling, are rate limiting and drive septum constriction in Staphylococcus aureus.
Live-cell single-molecule imaging reveals a single population of processive septal peptidoglycan synthases moving asynchronously with FtsZ that drive Bacillus subtilis cell constriction in a manner partially dependent upon FtsZ treadmilling.
Cryoelectron microscopy analyses of the counter-clockwise and clockwise states of the Salmonella Typhimurium C-ring reveal the structural bases for changes in rotation of the bacterial flagellum.
Experimental evolution of Pseudomonas aeruginosa shows that the population is more vulnerable to invading cheaters in a spatially extended system due to a higher level of cooperation.
Two studies describe the discovery of proteins that harbour a photosynthetic reaction centre barrel domain and play pivotal roles in FtsZ-mediated cell division in archaea, with the photosynthetic reaction centre fold itself emerging as a key player in executing cytokinesis across archaea.
The bacterial alarmone (p)ppGpp induces β-lactam resistance through modification of RNA polymerase and ribosome function rather than regulation of peptidoglycan metabolism in Escherichia coli.
Biochemical, genetic and structural analyses show how phage ΦKZ co-opts the Pseudomonasaeruginosa gene expression machinery using a factor that binds to host ribosomes at 5S ribosomal RNA.
During archaeal cell division, proteins containing photosynthetic reaction centre domains enable the formation of a defined cell division plane by direct interaction with SepF.
Metabolic engineers and synthetic biologists can produce recombinant proteins at scale without royalty payments, or strain distribution constraints, using OPENPichia.
A set of computational tools to de novo recognize plasmids in complex environments, like the human gut microbiome, and to organize them into evolutionarily cohesive units.
