    Gene Drive: A family of killers

    Mickaël De Carvalho, Sarah E Zanders
    Spok genes are meiotic drivers that increase their own chances of transmission by killing gametes that do not inherit them.

    wtf genes are prolific dual poison-antidote meiotic drivers

    Nicole L Nuckolls et al.
    Selfish wtf meiotic drive genes use overlapping transcripts to encode both a trans-acting poison to kill gametes that do not inherit the gene and a gamete-autonomous antidote to specifically rescue the gametes that do.

    An updated phylogeny of the Alphaproteobacteria reveals that the parasitic Rickettsiales and Holosporales have independent origins

    Sergio A Muñoz-Gómez et al.
    Diverse sophisticated phylogenetic analyses update the phylogeny of the Alphaproteobacteria and show that the parasitic Holosporales is a derived group within the Rhodospirillales order which comprises primarily free-living alphaproteobacteria.

    A complete toolset for the study of Ustilago bromivora and Brachypodium sp. as a fungal-temperate grass pathosystem

    Franziska Rabe et al.
    The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.

    Bacterial cell cycle control by citrate synthase independent of enzymatic activity

    Matthieu Bergé et al.
    A key enzyme of central energy metabolism, citrate synthase, regulates bacterial cell cycle progression at a very specific stage (S-phase) and independently of its enzymatic activity.

    Loss of centromere function drives karyotype evolution in closely related Malassezia species

    Sundar Ram Sankaranarayanan et al.
    The centromeres in Malassezia species, by breakage or inactivation, facilitate genome rearrangements that can result in varying karyotypes and contribute to the evolution of these species.

    Structural basis for Scc3-dependent cohesin recruitment to chromatin

    Yan Li et al.
    The Cohesin subunit Scc3 contains a hook-shaped domain that binds to DNA substrate, thus revealing that Cohesin-chromatin transactions are driven not only by topological interactions, but also by direct protein-DNA contacts.

    Changes of mitochondrial ultrastructure and function during ageing in mice and Drosophila

    Tobias Brandt et al.
    Respiratory activity and inner membrane organisation of mitochondria from Drosophila melanogaster break down during ageing, but mouse heart mitochondria appear to be protected against age-related damage.
