    The role of APETALA1 in petal number robustness

    Marie Monniaux et al.
    Variable petal number in Cardamine hirsuta is explained by regulatory changes in the MADS-box gene APETALA1 that relaxed its epistasis over mapped QTL in the C. hirsuta genome.

    Fine-tuning citrate synthase flux potentiates and refines metabolic innovation in the Lenski evolution experiment

    Erik M Quandt et al.
    A long-term evolution experiment with Escherichia coli shows that the appearance and optimization of a new trait can require both co-opting existing cellular pathways for new roles and reversing a history of previous adaptation.

    A map of directional genetic interactions in a metazoan cell

    Bernd Fischer et al.
    A systematic analysis of gene–gene dependencies using high-throughput imaging of cells detects causal and temporal relationships between genes.

    Adaptive substitutions underlying cardiac glycoside insensitivity in insects exhibit epistasis in vivo

    Andrew M Taverner et al.
    Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

    Science Forum: Viral factors in influenza pandemic risk assessment

    Marc Lipsitch et al.
    We identify key strengths and limitations in use of viral genotyping and phenotyping to estimate pandemic risk from influenza A viruses, focusing on 3 traits, hemagglutinin binding specificity, hemagglutinin pH of activation, and polymerase complex efficiency.

    Science Forum: The single-cell eQTLGen consortium

    MGP van der Wijst et al.
    The single-cell eQTLGen consortium aims to pinpoint the cellular contexts in which disease-causing genetic variants affect gene expression and its regulation.

    Systematic identification of cis-regulatory variants that cause gene expression differences in a yeast cross

    Kaushik Renganaath et al.
    Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.
