Description: Bacterial interactions in a synthetic plant leaf microbial community.

Description: RNA-sequencing of gut and different brain regions of gnotobiotic honeybees.

Description: Here we use honeybees to probe the effect of the gut microbiota on host social behavior. We found that the microbiota increased the rate of interaction between bees and the complexity of the emergent colony social network. Microbiota colonization was associated with higher abundances of one third of the metabolites detected in the brain, including amino acids with roles in synaptic transmission and brain energetic function. A subset of these metabolites were significant predictors of the number of social interactions of bees. Microbiota colonization also affected brain transcriptional processes related to amino acid metabolism and epigenetic modifications, particularly in areas of the brain implicated in sensory perception. These results demonstrate considerable effects of the gut microbiota on honeybee social organization and highlight the associated changes in individual neurophysiology.

Description: Profiling the taxonomic composition of microbial communities commonly involves the classification of ribosomal RNA gene fragments. As a trade-off to maintain high classification accuracy, existing tools are typically limited to the genus level. Here, we present mTAGs, a taxonomic profiling tool that implements the alignment of metagenomic sequencing reads to degenerate consensus reference sequences of small subunit ribosomal RNA genes. It uses DNA fragments, that is, paired-end sequencing reads, as count units and provides relative abundance profiles at multiple taxonomic ranks, including operational taxonomic units based on a 97% sequence identity cutoff. At the genus rank, mTAGs outperformed other tools across several metrics, such as the F1 score by >11% across data from different environments, and achieved competitive (F1 score) or better results (Bray–Curtis dissimilarity) at the sub-genus level. The software tool mTAGs is implemented in Python.

Description: The goal of this study was to quantify genome-wide gene expression differences of the aromatic-compound degrading bacterium Pseudomonas veronii 1YdBTEX2 upon inoculation in a variety of soils, contaminated or not with external toluene.

Description: Culture-independent profiling of the bacterial root microbiota shows that different plant species are colonized by distinct bacterial communities that provide beneficial services to the host. It is, however, not known to what extent the host actively selects these communities and whether commensal bacteria are adapted to a specific plant species. Here, we report a sequence-indexed culture collection from roots and nodules of the model legume Lotus japonicus that contains representatives from the majority of species found in culture-independent profiles.

Description: There is accumulating evidence that the lower airway microbiota impacts lung health. However, the link between microbial community composition and lung homeostasis remains elusive. We combine amplicon sequencing and bacterial culturing to characterize the viable bacterial community in 234 longitudinal bronchoalveolar lavage samples from 64 lung transplant recipients and establish links to viral loads, host gene expression, lung function, and transplant health.

Description: Here, we describe longitudinal tracking for four cystic fibrosis patients. Following metagenomics sequencing of lung sputum, we find that the taxonomic identity of individual colonizer lineages can be easily established. Crucially, even superficially clonal pathogens can be subdivided into multiple sub-lineages at the sequence level. By tracking individual allelic differences over time, an assembly-free clustering approach allows us to reconstruct multiple lineage-specific genomes with clear structural differences.
