    Natural mismatch repair mutations mediate phenotypic diversity and drug resistance in Cryptococcus deuterogattii

    R Blake Billmyre et al.
    Eukaryotic pathogens, like Cryptococcus deuterogattii, can use elevated mutation rates to more rapidly adapt to stresses, such as drug challenges, but at the cost of lower fitness in less stressful environments.

    Adaptability of non-genetic diversity in bacterial chemotaxis

    Nicholas W Frankel et al.
    An experimentally constrained model shows that Escherichia coli faces fitness trade-offs in chemotaxis behaviors, and that adaptation of phenotypic diversity through altered gene regulation permits populations to resolve these trade-offs.

    Phenotypic diversity and temporal variability in a bacterial signaling network revealed by single-cell FRET

    Johannes M Keegstra et al.
    Noise in a signaling network comprising thousands of molecules shapes diversity across cell populations and generates giant temporal fluctuations at the single-cell level.

    Phenotypic Diversity: Setting the bar

    Charles Y Feigin, Ricardo Mallarino
    Analyzing the genomes of rock pigeons demonstrates that genetic variation comes in many forms and can have unexpected origins.

    Phenotype inference in an Escherichia coli strain panel

    Marco Galardini et al.
    The mechanistic impact of genetic variants can be combined with previous knowledge on gene function to deliver conditional growth predictions and pave the way for personalized genetic interventions.

    TGF-β reduces DNA ds-break repair mechanisms to heighten genetic diversity and adaptability of CD44+/CD24− cancer cells

    Debjani Pal et al.
    Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.

    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.

    Multivariate analysis of electrophysiological diversity of Xenopus visual neurons during development and plasticity

    Christopher M Ciarleglio et al.
    The diversity of electrophysiological phenotypes of neurons in a functional network increases over development, but can be modulated, and even reduced by sensory experience; allowing them to adapt to a changing and growing brain.
