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

    Grant Kinsler, Kerry Geiler-Samerotte, Dmitri A Petrov
    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.

    A meta-analysis of genome-wide association studies of childhood wheezing phenotypes identifies ANXA1 as a susceptibility locus for persistent wheezing

    Raquel Granell, John A Curtin ... Adnan Custovic
    Using unique data from five longitudinal UK birth cohorts, four distinct subsets of genetic variants were identified as differentially associated across wheezing phenotypes from infancy to adolescence with little evidence of genetic associations spanning across different phenotypes.

    Rescuable sleep and synaptogenesis phenotypes in a Drosophila model of O-GlcNAc transferase intellectual disability

    Ignacy Czajewski, Bijayalaxmi Swain ... Daan MF van Aalten
    Modelling O-GlcNAc transferase intellectual disability reveals the roles of this post-translational modification in regulating normal axonal terminal morphology and maintaining appropriate sleep homeostasis, pharmacological and genetic rescues of O-GlcNAcylation highlight the complexities of addressing this disorder.

    Relating multivariate shapes to genescapes using phenotype-biological process associations for craniofacial shape

    Jose D Aponte, David C Katz ... Benedikt Hallgrímsson
    Multivariate genotype-phenotype mapping enables quantification of pathway and process-level effects on complex phenotypes and predicts phenotypic effects of novel mutations.

    Barcoded bulk QTL mapping reveals highly polygenic and epistatic architecture of complex traits in yeast

    Alex N Nguyen Ba, Katherine R Lawrence ... Michael M Desai
    A bulk barcoded quantitative trait locus approach increases the power and resolution of genotype-phenotype mapping in yeast, revealing that the genetic architecture of 18 complex traits is highly polygenic, and is characterized by widespread epistatic interactions and pleiotropic effects.

    Phenotypic states become increasingly sensitive to perturbations near a bifurcation in a synthetic gene network

    Kevin Axelrod, Alvaro Sanchez, Jeff Gore
    Perturbations in the extracellular environment drive transitions from a highly stable memory state to an alternative phenotype in microorganisms.

    Cannabinoid signaling modulation through JZL184 restores key phenotypes of a mouse model for Williams–Beuren syndrome

    Alba Navarro-Romero, Lorena Galera-López ... Andres Ozaita
    A mouse model of Williams–Beuren syndrome allowed us to assess the endocannabinoid system and the impact of targeting the monoacyl glycerol lipase in modulating key phenotypes such as cognitive and hypersocial phenotype as well as the cardiac phenotype.

    Plant defense phenotypes determine the consequences of volatile emission for individuals and neighbors

    Meredith C Schuman, Silke Allmann, Ian T Baldwin
    Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

    Modeling single-cell phenotypes links yeast stress acclimation to transcriptional repression and pre-stress cellular states

    Andrew C Bergen, Rachel A Kocik ... Audrey P Gasch
    Counterintuitively, activation of the transcriptional repressor of growth-promoting genes is important for yeast cell acclimation to salt stress, such that cells with larger activation of the repressor tend to have faster growth acclimation after stress.

    Association analyses of host genetics, root-colonizing microbes, and plant phenotypes under different nitrogen conditions in maize

    Michael A Meier, Gen Xu ... Jinliang Yang
    Comprehensive analyses of host genetics, root-associated microbiomes, and plant phenotypes under two nitrogen treatments reveals host genetic control of microbe abundance which, in turn, affects plant performance.
