    Secondary metabolites are widely used in human health and nutrition, but extraction yields from plants are often low. Nakagawaet al. have engineered the metabolism of Escherichia colito develop a fermentation system that produces plant alkaloids from simple carbon sources.

    Plasmids are present in many bacteria and are often transferred between different species causing horizontal gene transfer. By comparing the sequences of 25 plasmid DNA backbones, the authors show that homologous recombination is prevalent in plasmids and that the plasmids have adapted to persist in different host bacteria.

    Proteorhodopsin is used by prokaryotes to generate energy from light. In this study, the authors describe a prokaryote-to-eukaryote horizontal gene transfer of a bacterial proteorhodopsin gene to dinoflagellates, suggesting that these eukaryotes can also use proteorhodopsin to obtain light and produce energy.

    HrpR and HrpS enhancer-binding proteins ofPseudomonas syringae activate σ54-dependent transcription of the HrpL promoter and are required for type-three secretion pathogenicity. Here, the authors demonstrate that, despite being co-regulated, HrpR and HrpS each have distinct functions for activating σ54.

    Microorganisms are abundant in many environments and understanding their dispersal between ecosystems is important for ecology and conservation. These authors demonstrate that cyanobacterial populations are specific to hot or cold deserts and that gene flow between different populations does not occur.

    Insertion sequences are transposable elements that are found in the genomes of many bacteria. Here, the authors identify an enhancer element that results in a high frequency of excision of insertion elements, and suggest that the excision enhancer element coevolved with the insertion sequences.

    Up to 20% of bacterial genomes are made up of cryptic prophages, but their function is relatively unknown. In this study, the authors demonstrate that prophages influence the response of the host cell to stress and provide a competitive growth advantage in the presence of antibiotics.

    Identifying the transcripts and proteins that fluctuate in response to stimuli provides important information for understanding cell physiology. In this study, 52% of theBacillus subtilispredicted proteome is identified following glucose starvation, revealing further insight into protein dynamics at a global scale.

    Hydrogen production using photosynthetic bacteria is an appealing energy source, but typically the bacteria require anaerobic conditions. Here, the authors report a wild-type cyanobacterium strain that shows very high rates of hydrogen production under aerobic environmental conditions.

    Candidate anti-tuberculosis drugs are often identified in whole-cell screens. Here, Petheet al. show that inappropriate carbon-source selection can lead to the identification of compounds devoid of efficacy in vivo, underlining the importance of developing predictive in vitroscreens.

    The spatial distribution and parameters that affect soil microorganism communities are largely unknown. In this study, bacterial communities up to 240 metres apart are shown to be similar and are affected by soil pH, plant abundance and snow depth.

    To ensure correct cell division Staphylococci must remember which plane they previously divided along, but the mechanism by which this is achieved is unclear. In this article, using atomic force microscopy, peptidoglycan ribs are reported to mark previous planes of division.

    Peptidoglycans provide bacterial cell walls with mechanical strength. The spatial organization of peptidoglycan has previously been difficult to study. Here, atomic force microscopy, together with cells carrying mutations in cell-wall polysaccharides, has allowed an in-depth study of these molecules.
