  text: Predicting function from sequence is a central problem of biology. Currently,
    this is possible only locally in a narrow mutational neighborhood around a wildtype
    sequence rather than globally from any sequence. Using random mutant libraries,
    we developed a biophysical model that accounts for multiple features of σ70 binding
    bacterial promoters to predict constitutive gene expression levels from any sequence.
    We experimentally and theoretically estimated that 10–20% of random sequences
    lead to expression and ~80% of non-expressing sequences are one mutation away
    from a functional promoter. The potential for generating expression from random
    sequences is so pervasive that selection acts against σ70-RNA polymerase binding
    sites even within inter-genic, promoter-containing regions. This pervasiveness
    of σ70-binding sites implies that emergence of promoters is not the limiting step
    in gene regulatory evolution. Ultimately, the inclusion of novel features of promoter
    function into a mechanistic model enabled not only more accurate predictions of
    gene expression levels, but also identified that promoters evolve more rapidly
    than previously thought.

  text: Organisms cope with change by taking advantage of transcriptional regulators.
    However, when faced with rare environments, the evolution of transcriptional regulators
    and their promoters may be too slow. Here, we investigate whether the intrinsic
    instability of gene duplication and amplification provides a generic alternative
    to canonical gene regulation. Using real-time monitoring of gene-copy-number mutations
    in Escherichia coli, we show that gene duplications and amplifications enable
    adaptation to fluctuating environments by rapidly generating copy-number and,
    therefore, expression-level polymorphisms. This amplification-mediated gene expression
    tuning (AMGET) occurs on timescales that are similar to canonical gene regulation
    and can respond to rapid environmental changes. Mathematical modelling shows that
    amplifications also tune gene expression in stochastic environments in which transcription-factor-based
    schemes are hard to evolve or maintain. The fleeting nature of gene amplifications
    gives rise to a generic population-level mechanism that relies on genetic heterogeneity
    to rapidly tune the expression of any gene, without leaving any genomic signature.

  text: 'Gene regulatory networks evolve through rewiring of individual components—that
    is, through changes in regulatory connections. However, the mechanistic basis
    of regulatory rewiring is poorly understood. Using a canonical gene regulatory
    system, we quantify the properties of transcription factors that determine the
    evolutionary potential for rewiring of regulatory connections: robustness, tunability
    and evolvability. In vivo repression measurements of two repressors at mutated
    operator sites reveal their contrasting evolutionary potential: while robustness
    and evolvability were positively correlated, both were in trade-off with tunability.
    Epistatic interactions between adjacent operators alleviated this trade-off. A
    thermodynamic model explains how the differences in robustness, tunability and
    evolvability arise from biophysical characteristics of repressor–DNA binding.
    The model also uncovers that the energy matrix, which describes how mutations
    affect repressor–DNA binding, encodes crucial information about the evolutionary
    potential of a repressor. The biophysical determinants of evolutionary potential
    for regulatory rewiring constitute a mechanistic framework for understanding network
    evolution.'

  text: Herd immunity, a process in which resistant individuals limit the spread of
    a pathogen among susceptible hosts has been extensively studied in eukaryotes.
    Even though bacteria have evolved multiple immune systems against their phage
    pathogens, herd immunity in bacteria remains unexplored. Here we experimentally
    demonstrate that herd immunity arises during phage epidemics in structured and
    unstructured Escherichia coli populations consisting of differing frequencies
    of susceptible and resistant cells harboring CRISPR immunity. In addition, we
    develop a mathematical model that quantifies how herd immunity is affected by
    spatial population structure, bacterial growth rate, and phage replication rate.
    Using our model we infer a general epidemiological rule describing the relative
    speed of an epidemic in partially resistant spatially structured populations.
    Our experimental and theoretical findings indicate that herd immunity may be important
    in bacterial communities, allowing for stable coexistence of bacteria and their
    phages and the maintenance of polymorphism in bacterial immunity.

  text: Viral capsids are structurally constrained by interactions among the amino
    acids (AAs) of their constituent proteins. Therefore, epistasis is expected to
    evolve among physically interacting sites and to influence the rates of substitution.
    To study the evolution of epistasis, we focused on the major structural protein
    of the fX174 phage family by first reconstructing the ancestral protein sequences
    of 18 species using a Bayesian statistical framework. The inferred ancestral reconstruction
    differed at eight AAs, for a total of 256 possible ancestral haplotypes. For each
    ancestral haplotype and the extant species, we estimated, in silico, the distribution
    of free energies and epistasis of the capsid structure. We found that free energy
    has not significantly increased but epistasis has. We decomposed epistasis up
    to fifth order and found that higher-order epistasis sometimes compensates pairwise
    interactions making the free energy seem additive. The dN/dS ratio is low, suggesting
    strong purifying selection, and that structure is under stabilizing selection.
    We synthesized phages carrying ancestral haplotypes of the coat protein gene and
    measured their fitness experimentally. Our findings indicate that stabilizing
    mutations can have higher fitness, and that fitness optima do not necessarily
    coincide with energy minima.

  text: 'Most phenotypes are determined by molecular systems composed of specifically
    interacting molecules. However, unlike for individual components, little is known
    about the distributions of mutational effects of molecular systems as a whole.
    We ask how the distribution of mutational effects of a transcriptional regulatory
    system differs from the distributions of its components, by first independently,
    and then simultaneously, mutating a transcription factor and the associated promoter
    it represses. We find that the system distribution exhibits increased phenotypic
    variation compared to individual component distributions - an effect arising from
    intermolecular epistasis between the transcription factor and its DNA-binding
    site. In large part, this epistasis can be qualitatively attributed to the structure
    of the transcriptional regulatory system and could therefore be a common feature
    in prokaryotes. Counter-intuitively, intermolecular epistasis can alleviate the
    constraints of individual components, thereby increasing phenotypic variation
    that selection could act on and facilitating adaptive evolution. '

  text: Understanding the relation between genotype and phenotype remains a major
    challenge. The difficulty of predicting individual mutation effects, and particularly
    the interactions between them, has prevented the development of a comprehensive
    theory that links genotypic changes to their phenotypic effects. We show that
    a general thermodynamic framework for gene regulation, based on a biophysical
    understanding of protein-DNA binding, accurately predicts the sign of epistasis
    in a canonical cis-regulatory element consisting of overlapping RNA polymerase
    and repressor binding sites. Sign and magnitude of individual mutation effects
    are sufficient to predict the sign of epistasis and its environmental dependence.
    Thus, the thermodynamic model offers the correct null prediction for epistasis
    between mutations across DNA-binding sites. Our results indicate that a predictive
    theory for the effects of cis-regulatory mutations is possible from first principles,
    as long as the essential molecular mechanisms and the constraints these impose
    on a biological system are accounted for.

  text: Changes in gene expression are an important mode of evolution; however, the
    proximate mechanism of these changes is poorly understood. In particular, little
    is known about the effects of mutations within cis binding sites for transcription
    factors, or the nature of epistatic interactions between these mutations. Here,
    we tested the effects of single and double mutants in two cis binding sites involved
    in the transcriptional regulation of the Escherichia coli araBAD operon, a component
    of arabinose metabolism, using a synthetic system. This system decouples transcriptional
    control from any posttranslational effects on fitness, allowing a precise estimate
    of the effect of single and double mutations, and hence epistasis, on gene expression.
    We found that epistatic interactions between mutations in the araBAD cis-regulatory
    element are common, and that the predominant form of epistasis is negative. The
    magnitude of the interactions depended on whether the mutations are located in
    the same or in different operator sites. Importantly, these epistatic interactions
    were dependent on the presence of arabinose, a native inducer of the araBAD operon
    in vivo, with some interactions changing in sign (e.g., from negative to positive)
    in its presence. This study thus reveals that mutations in even relatively simple
    cis-regulatory elements interact in complex ways such that selection on the level
    of gene expression in one environment might perturb regulation in the other environment
    in an unpredictable and uncorrelated manner.

  text: Viral capsids are structurally constrained by interactions among the amino
    acids (AAs) of their constituent proteins. Therefore, epistasis is expected to
    evolve among physically interacting sites and to influence the rates of substitution.
    To study the evolution of epistasis, we focused on the major structural protein
    of the ϕX174 phage family by, first, reconstructing the ancestral protein sequences
    of 18 species using a Bayesian statistical framework. The inferred ancestral reconstruction
    differed at eight AAs, for a total of 256 possible ancestral haplotypes. For each
    ancestral haplotype and the extant species, we estimated, in silico, the distribution
    of free energies and epistasis of the capsid structure. We found that free energy
    has not significantly increased but epistasis has. We decomposed epistasis up
    to fifth order and found that higher-order epistasis sometimes compensates pairwise
    interactions making the free energy seem additive. The dN/dS ratio is low, suggesting
    strong purifying selection, and that structure is under stabilizing selection.
    We synthesized phages carrying ancestral haplotypes of the coat protein gene and
    measured their fitness experimentally. Our findings indicate that stabilizing
    mutations can have higher fitness, and that fitness optima do not necessarily
    coincide with energy minima.

  text: 'Background: CRISPR is a microbial immune system likely to be involved in
    host-parasite coevolution. It functions using target sequences encoded by the
    bacterial genome, which interfere with invading nucleic acids using a homology-dependent
    system. The system also requires protospacer associated motifs (PAMs), short motifs
    close to the target sequence that are required for interference in CRISPR types
    I and II. Here, we investigate whether PAMs are depleted in phage genomes due
    to selection pressure to escape recognition.Results: To this end, we analyzed
    two data sets. Phages infecting all bacterial hosts were analyzed first, followed
    by a detailed analysis of phages infecting the genus Streptococcus, where PAMs
    are best understood. We use two different measures of motif underrepresentation
    that control for codon bias and the frequency of submotifs. We compare phages
    infecting species with a particular CRISPR type to those infecting species without
    that type. Since only known PAMs were investigated, the analysis is restricted
    to CRISPR types I-C and I-E and in Streptococcus to types I-C and II. We found
    evidence for PAM depletion in Streptococcus phages infecting hosts with CRISPR
    type I-C, in Vibrio phages infecting hosts with CRISPR type I-E and in Streptococcus
    thermopilus phages infecting hosts with type II-A, known as CRISPR3.Conclusions:
    The observed motif depletion in phages with hosts having CRISPR can be attributed
    to selection rather than to mutational bias, as mutational bias should affect
    the phages of all hosts. This observation implies that the CRISPR system has been
    efficient in the groups discussed here.'

  text: 'Background: The CRISPR/Cas system is known to act as an adaptive and heritable
    immune system in Eubacteria and Archaea. Immunity is encoded in an array of spacer
    sequences. Each spacer can provide specific immunity to invasive elements that
    carry the same or a similar sequence. Even in closely related strains, spacer
    content is very dynamic and evolves quickly. Standard models of nucleotide evolutioncannot
    be applied to quantify its rate of change since processes other than single nucleotide
    changes determine its evolution.Methods We present probabilistic models that are
    specific for spacer content evolution. They account for the different processes
    of insertion and deletion. Insertions can be constrained to occur on one end only
    or are allowed to occur throughout the array. One deletion event can affect one
    spacer or a whole fragment of adjacent spacers. Parameters of the underlying models
    are estimated for a pair of arrays by maximum likelihood using explicit ancestor
    enumeration.Results Simulations show that parameters are well estimated on average
    under the models presented here. There is a bias in the rate estimation when including
    fragment deletions. The models also estimate times between pairs of strains. But
    with increasing time, spacer overlap goes to zero, and thus there is an upper
    bound on the distance that can be estimated. Spacer content similarities are displayed
    in a distance based phylogeny using the estimated times.We use the presented models
    to analyze different Yersinia pestis data sets and find that the results among
    them are largely congruent. The models also capture the variation in diversity
    of spacers among the data sets. A comparison of spacer-based phylogenies and Cas
    gene phylogenies shows that they resolve very different time scales for this data
    set.Conclusions The simulations and data analyses show that the presented models
    are useful for quantifying spacer content evolution and for displaying spacer
    content similarities of closely related strains in a phylogeny. This allows for
    comparisons of different CRISPR arrays or for comparisons between CRISPR arrays
    and nucleotide substitution rates.'

  text: 'Background: Reassortment between the RNA segments encoding haemagglutinin
    (HA) and neuraminidase (NA), the major antigenic influenza proteins, produces
    viruses with novel HA and NA subtype combinations and has preceded the emergence
    of pandemic strains. It has been suggested that productive viral infection requires
    a balance in the level of functional activity of HA and NA, arising from their
    closely interacting roles in the viral life cycle, and that this functional balance
    could be mediated by genetic changes in the HA and NA. Here, we investigate how
    the selective pressure varies for H7 avian influenza HA on different NA subtype
    backgrounds. Results: By extending Bayesian stochastic mutational mapping methods
    to calculate the ratio of the rate of non-synonymous change to the rate of synonymous
    change (d N/d S), we found the average d N/d S across the avian influenza H7 HA1
    region to be significantly greater on an N2 NA subtype background than on an N1,
    N3 or N7 background. Observed differences in evolutionary rates of H7 HA on different
    NA subtype backgrounds could not be attributed to underlying differences between
    avian host species or virus pathogenicity. Examination of d N/d S values for each
    subtype on a site-by-site basis indicated that the elevated d N/d S on the N2
    NA background was a result of increased selection, rather than a relaxation of
    selective constraint. Conclusions: Our results are consistent with the hypothesis
    that reassortment exposes influenza HA to significant changes in selective pressure
    through genetic interactions with NA. Such epistatic effects might be explicitly
    accounted for in future models of influenza evolution.'

  text: Phenotypic biotyping has traditionally been used to differentiate bacteria
    occupying distinct ecological niches such as host species. For example, the capacity
    of Staphylococcus aureus from sheep to coagulate ruminant plasma, reported over
    60 years ago, led to the description of small ruminant and bovine S. aureus ecovars.
    The great majority of small ruminant isolates are represented by a single, widespread
    clonal complex (CC133) of S. aureus, but its evolutionary origin and the molecular
    basis for its host tropism remain unknown. Here, we provide evidence that the
    CC133 clone evolved as the result of a human to ruminant host jump followed by
    adaptive genome diversification. Comparative whole-genome sequencing revealed
    molecular evidence for host adaptation including gene decay and diversification
    of proteins involved in host-pathogen interactions. Importantly, several novel
    mobile genetic elements encoding virulence proteins with attenuated or enhanced
    activity in ruminants were widely distributed in CC133 isolates, suggesting a
    key role in its host-specific interactions. To investigate this further, we examined
    the activity of a novel staphylococcal pathogenicity island (SaPIov2) found in
    the great majority of CC133 isolates which encodes a variant of the chromosomally
    encoded von Willebrand-binding protein (vWbp(Sov2)), previously demonstrated to
    have coagulase activity for human plasma. Remarkably, we discovered that SaPIov2
    confers the ability to coagulate ruminant plasma suggesting an important role
    in ruminant disease pathogenesis and revealing the origin of a defining phenotype
    of the classical S. aureus biotyping scheme. Taken together, these data provide
    broad new insights into the origin and molecular basis of S. aureus ruminant host
    specificity.

  text: Parallel evolution is the acquisition of identical adaptive traits in independently
    evolving populations. Understanding whether the genetic changes underlying adaptation
    to a common selective environment are parallel within and between species is interesting
    because it sheds light on the degree of evolutionary constraints. If parallel
    evolution is perfect, then the implication is that forces such as functional constraints,
    epistasis, and pleiotropy play an important role in shaping the outcomes of adaptive
    evolution. In addition, population genetic theory predicts that the probability
    of parallel evolution will decline with an increase in the number of adaptive
    solutions-if a single adaptive solution exists, then parallel evolution will be
    observed among highly divergent species. For this reason, it is predicted that
    close relatives-which likely overlap more in the details of their adaptive solutions-will
    show more parallel evolution. By adapting three related bacteriophage species
    to a novel environment we find (1) a high rate of parallel genetic evolution at
    orthologous nucleotide and amino acid residues within species, (2) parallel beneficial
    mutations do not occur in a common order in which they fix or appear in an evolving
    population, (3) low rates of parallel evolution and convergent evolution between
    species, and (4) the probability of parallel and convergent evolution between
    species is strongly effected by divergence.

  text: We develop a new method for estimating effective population sizes, Ne, and
    selection coefficients, s, from time-series data of allele frequencies sampled
    from a single diallelic locus. The method is based on calculating transition probabilities,
    using a numerical solution of the diffusion process, and assuming independent
    binomial sampling from this diffusion process at each time point. We apply the
    method in two example applications. First, we estimate selection coefficients
    acting on the CCR5-Δ32 mutation on the basis of published samples of contemporary
    and ancient human DNA. We show that the data are compatible with the assumption
    of s = 0, although moderate amounts of selection acting on this mutation cannot
    be excluded. In our second example, we estimate the selection coefficient acting
    on a mutation segregating in an experimental phage population. We show that the
    selection coefficient acting on this mutation is ~0.43.

  text: Evolution has left its signature on the molecules and morphology of living
    organisms. Ancestral reconstruction offers an excellent tool for understanding
    the process of evolution using comparative information. Methods for ancestral
    reconstruction have generally focused on reconstructing the ancestral states at
    the internal nodes of a phylogeny. Often, we are not interested in particular
    nodes of the phylogeny but the whole history of a character. This chapter focuses
    on a Bayesian method for estimating these histories, or mutational paths, on phylogenies.
    Mutational path methods differ most notably from other approaches in their ability
    to estimate not only the ancestral states at the internal nodes of a phylogeny,
    but also the order and timing of mutational changes across the phylogeny. The
    chapter provides a concise introduction to the statistical tools needed for sampling
    mutational paths on a phylogeny.

  text: 'he potential for di? erences between genetic paternity and paternity inferred
    from behavioral observation has long been recognized. These di? erences are associated
    with the challenge for females of seeking both genetic and material bene? ts;
    this challenge is less severe in species with polygynous, non-resource-based mating
    systems (such as leks) than in those with resource-based systems. We pres- ent
    the ? rst study of paternity patt erns in a non-resource-based species that does
    not form true leks. We compared paternity inferred from observed mating behavior
    to genetically assigned paternity in the Satin Bowerbird (Ptilonorhynchus violaceus)
    using eight microsatellite markers. Mating behavior was observed and recorded
    via automated video-cameras positioned at all bowers (29?34 bowers each year)
    in the study site throughout each mating season. We obtained blood samples and
    identi- ? ed mothers for 11 chicks in 9 nests. For all chicks, the most likely
    genetic father had been observed to mate with the mother in the year the chick
    was sampled. All most likely genetic fathers were assigned with high con? dence
    and all were bower- holding males. These results demonstrate that genetic paternity
    can be inferred from observed mating behavior with reasonable con? dence in Satin
    Bowerbirds. Observed male mating-success is therefore a reliable predictor of
    reproductive success, and this suggests that high skew in observed male mating-success
    translates directly to high skew in reproductive success. '
