    Natural genetic variation in Arabidopsis thaliana defense metabolism genes modulates field fitness

    Rachel Kerwin et al.
    Environmental heterogeneity may contribute to the high levels of genetic variation in glucosinolate genes found in Arabidopsis thaliana.

    Natural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting

    Daniela Pignatta et al.
    Individual scientists, scientific communities and scientific journals can do more to assess the publication of irreproducible results, to promote good science, and to increase the efficiency with which the scientific community self-corrects.

    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.

    Natural variation in C. elegans arsenic toxicity is explained by differences in branched chain amino acid metabolism

    Stefan Zdraljevic et al.
    Quantitative genetics approaches using Caenorhabditis elegans facilitate the discovery of a novel arsenic toxicity mechanism.

    Natural variation in stochastic photoreceptor specification and color preference in Drosophila

    Caitlin Anderson et al.
    Binding site affinity and transcription factor levels are finely tuned in nature to regulate stochastic expression, setting the ratio of alternative photoreceptor fates and determining color preference.

    A natural variant of the essential host gene MMS21 restricts the parasitic 2-micron plasmid in Saccharomyces cerevisiae

    Michelle Hays et al.
    A novel assay to measure 2-micron stability together with a survey of natural variation among Saccharomyces cerevisiae strains reveals novel means by which yeasts can combat the parasitic 2-micron plasmids.

    Natural variation in sugar tolerance associates with changes in signaling and mitochondrial ribosome biogenesis

    Richard G Melvin et al.
    The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.

    Developmental evolution of the forebrain in cavefish, from natural variations in neuropeptides to behavior

    Alexandre Alié et al.
    A comparative approach shows that developmental evolution of neuropeptidergic neuronal groups in the hypothalamus of blind cavefish drives adaptive behavioral evolution.

    Natural variation reveals that intracellular distribution of ELF3 protein is associated with function in the circadian clock

    Muhammad Usman Anwer et al.
    In Arabidopsis, a natural variant of the ELF3 protein, which originated in Central Asia, is less likely to accumulate in the nucleus, and causes the circadian clock to run faster and be less responsive to environmental cues.

    Variation in natural exposure to anopheles mosquitoes and its effects on malaria transmission

    Wamdaogo M Guelbéogo et al.
    Heterogeneity in exposure to malaria vectors, including sporozoite-infected mosquitoes, contributes to the variation in human infection risk and amplifies the local transmission potential.
