    Regulated aggregative multicellularity in a close unicellular relative of metazoa

    Arnau Sebé-Pedrós, Manuel Irimia ... Iñaki Ruiz-Trillo
    The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.

    A secreted Ustilago maydis effector promotes virulence by targeting anthocyanin biosynthesis in maize

    Shigeyuki Tanaka, Thomas Brefort ... Regine Kahmann
    A fungal effector secreted by the corn smut pathogen increases the virulence of the pathogen by elevating anthocyanin production and reducing lignification in maize.

    MELK is an oncogenic kinase essential for mitotic progression in basal-like breast cancer cells

    Yubao Wang, Young-Mi Lee ... Jean J Zhao
    Maternal embryonic leucine zipper kinase (MELK) is a new anti-cancer target that is highly selective for basal-like breast cancer.

    Loss of the multifunctional RNA-binding protein RBM47 as a source of selectable metastatic traits in breast cancer

    Sakari Vanharanta, Christina B Marney ... Joan Massagué
    Inactivation of a multifunctional RNA-binding protein can lead to the acquisition of pro-metastatic phenotypes, possibly by stabilizing large-scale transcriptomic changes that provide a selective advantage during cancer progression.

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

    Julia Mallmann, David Heckmann ... Udo Gowik
    Metabolic exaptation of an anaplerotic nitrogen cycle between bundle sheath and mesophyll cells may explain the remarkably frequent convergent evolution of C4 photosynthesis.

    Prediction and characterization of enzymatic activities guided by sequence similarity and genome neighborhood networks

    Suwen Zhao, Ayano Sakai ... Matthew P Jacobson
    Genome neighborhood networks provide an efficient large-scale approach to mine metabolic pathway context for entire families of proteins and enzymes.

    The long non-coding RNA Dali is an epigenetic regulator of neural differentiation

    Vladislava Chalei, Stephen N Sansom ... Chris P Ponting
    Dali regulates transcription of the Pou3f3 locus locally and binds and regulates active promoters in trans by modulating DNA methylation status.

    Genes associated with ant social behavior show distinct transcriptional and evolutionary patterns

    Alexander S Mikheyev, Timothy A Linksvayer
    Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.

    Systematic imaging reveals features and changing localization of mRNAs in Drosophila development

    Helena Jambor, Vineeth Surendranath ... Pavel Tomancak
    Genome wide analysis reveals that many transcripts are localized in cells of the ovary and that the localization status of mRNAs changes over time and in different cell types.

    Dosage compensation can buffer copy-number variation in wild yeast

    James Hose, Chris Mun Yong ... Audrey P Gasch
    Dosage-compensated gene expression facilitates chromosomal aneuploidy, which presents a rapid route to phenotypic evolution in natural yeast isolates.
