    The Aquilegia genome provides insight into adaptive radiation and reveals an extraordinarily polymorphic chromosome with a unique history

    Danièle L Filiault et al.
    The evolution columbine genus involved frequent mixing between incipient species, and one chromosome appears to have taken its own path.

    Cryptic genetic variation shapes the adaptive evolutionary potential of enzymes

    Florian Baier et al.
    Genetic change among enzyme orthologous with similar phenotypic properties can cause substantial differences in evolutionary response to a new enzyme function in terms of their molecular and fitness outcomes.

    Natural variation in autumn expression is the major adaptive determinant distinguishing Arabidopsis FLC haplotypes

    Jo Hepworth et al.
    Variation in autumnal expression from starting expression levels and initial cold-down-regulation, rather than epigenetic silencing, is the major field variable conferred by worldwide haplotypes of the floral repressor gene, FLC.

    Multiple alleles at a single locus control seed dormancy in Swedish Arabidopsis

    Envel Kerdaffrec et al.
    Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.

    Gene expression variability in human and chimpanzee populations share common determinants

    Benjamin Jung Fair et al.
    Similar evolutionary pressures on gene expression between human and chimpanzee populations contribute to the observation that inter-individual gene expression variability is similar across genes in these species.

    Evolutionary stability of collateral sensitivity to antibiotics in the model pathogen Pseudomonas aeruginosa

    Camilo Barbosa et al.
    Evolutionary trade-offs enhance efficacy of antibiotic therapy by constraining bacterial adaptation in dependence of drug order and trade-off effect size.

    Regulatory network structure determines patterns of intermolecular epistasis

    Mato Lagator et al.
    Greater phenotypic variation is exposed by mutations in a gene regulatory system compared to mutations in its constitutive components, namely the transcription factor and the promoter, alone.

    Extensive impact of low-frequency variants on the phenotypic landscape at population-scale

    Téo Fournier et al.
    Genome-wide association studies on a diallel yeast panel revealed the relevance of low-frequency variants on the phenotypic diversity and consequently on the missing heritability at a population-scale.

    Fitness variation across subtle environmental perturbations reveals local modularity and global pleiotropy of adaptation

    Grant Kinsler et al.
    A set of adaptive mutations affect only a small number of phenotypes that matter in the evolution condition, and yet contain substantial latent functional diversity revealed in distant environments.

    Local adaptation and archaic introgression shape global diversity at human structural variant loci

    Stephanie M Yan et al.
    Graph genotyping of structural variation in diverse human populations reveals functional associations and signatures of local adaptation within poorly resolved regions of the genome.
