TL;DR: The pyrosequencing of the bacterial 16S ribosomal RNA gene of more than 600 Arabidopsis thaliana plants is reported to test the hypotheses that the root rhizosphere and endophytic compartment microbiota of plants grown under controlled conditions in natural soils are sufficiently dependent on the host to remain consistent across different soil types and developmental stages.
Primer and platform effects on 16S rRNA tag sequencing.

TL;DR: It is found that paired-end MiSeq reads produce higher quality data and enabled the use of more aggressive quality control parameters over 454, resulting in a higher retention rate of high quality reads for downstream data analysis and Beta diversity metrics are surprisingly robust to both primer and sequencing platform biases.
Genome-wide selective sweeps and gene-specific sweeps in natural bacterial populations

TL;DR: Examination of changes in single-nucleotide polymorphism (SNP) frequencies and patterns of gene gain and loss in 30 bacterial populations revealed substantial genetic heterogeneity within these populations, although the degree of heterogeneity varied by >1000-fold among populations.
Swarming motility: a multicellular behaviour conferring antimicrobial resistance
TL;DR: The hypothesis that antimicrobial resistance is a general feature of bacterial multicellularity is supported, as swarming motility might represent a form of social behaviour useful as a model to investigate biofilm antibiotic resistance.

Self-produced extracellular stimuli modulate the Pseudomonas aeruginosa swarming motility behaviour.
TL;DR: A model explaining how HAAs and di-RLs together modulate the behaviour of swarming migrating cells by acting as self-produced negative and positive chemotactic-like stimuli is proposed.
