    Flexible nitrogen utilisation by the metabolic generalist pathogen Mycobacterium tuberculosis

    Aleksandra Agapova et al.
    Metabolomics and stable isotope labelling studies of virulent Mycobacterium tuberculosis reveal a de-centralised metabolic network able to utilise various amino acids as nitrogen sources to a better extent than ammonium.

    A tRNA modification balances carbon and nitrogen metabolism by regulating phosphate homeostasis

    Ritu Gupta et al.
    The role of an amino acid-dependent tRNA modification as a nutrient sensor and regulator of metabolic homeostasis has been discovered.

    The role of photorespiration during the evolution of C4 photosynthesis in the genus Flaveria

    Julia Mallmann et al.
    Metabolic exaptation of an anaplerotic nitrogen cycle between bundle sheath and mesophyll cells may explain the remarkably frequent convergent evolution of C4 photosynthesis.

    Phytotoxin production in Aspergillus terreus is regulated by independent environmental signals

    Markus Gressler et al.
    Elevated methionine levels, or a shortage of nitrogen or iron, induce terrein production in the fungus Aspergillus terreus.

    Health benefits attributed to 17α-estradiol, a lifespan-extending compound, are mediated through estrogen receptor α

    Shivani N Mann et al.
    17α-Estradiol, a life-span extending compound, signals through estrogen receptor α (ERα) in the liver and hypothalamus to elicit health benefits in a sex-specific manner.

    Quantifying absolute gene expression profiles reveals distinct regulation of central carbon metabolism genes in yeast

    Rosemary Yu et al.
    Global gene expression control mechanisms are modeled using a large dataset consisting of absolute-quantitative proteomics, transcriptomics, and partial metabolomics of Saccharomyces cerevisiae at a wide range of growth conditions.

    Metabolic co-dependence drives the evolutionarily ancient Hydra–Chlorella symbiosis

    Mayuko Hamada et al.
    The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.

    Chromatin mapping identifies BasR, a key regulator of bacteria-triggered production of fungal secondary metabolites

    Juliane Fischer et al.
    Genome-wide chromatin mapping during bacterial-fungal cocultivation identifies the Myb-like transcription factor BasR as the major regulatory node of bacteria-triggered production of fungal secondary metabolites.

    Transcriptome analysis illuminates the nature of the intracellular interaction in a vertebrate-algal symbiosis

    John A Burns et al.
    The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

    Ecology and evolution of viruses infecting uncultivated SUP05 bacteria as revealed by single-cell- and meta-genomics

    Simon Roux et al.
    Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.
