Paper Suggestions:

  • Peter & Ben's Games of life and death: antibiotic resistance and production through the lens of evolutionary game theory
  • Ben's Life cycles, fitness decoupling and the evolution of multicellularity
  • Character displacement and the evolution of niche complementarity in a model biofilm community - The paper focuses on the evolution of coexisting mutants within a population of Burkholderia cenocepacia and how their interactions affected productivity.
  • Evolutionary limits to cooperation in microbial communities - K.Foz and group use a model to look at microbial cooperation between different strains and species.
  • Alternating Antibiotic Treatments Constrain Evolutionary Paths to Multidrug Resistance - Using experimental evolution and whole-genome sequencing, we find that alternating drugs slows the rate of increase in resistance compared with single-drug treatments, by constraining resistance mutations with trade-offs in resistance to a second drug.
  • The Time Scale of Evolutionary Innovation - But here we ask a different question, which is concerned with the much longer time scale of evolutionary trajectories: how long does it take for a population exploring a fitness landscape to find target sequences that encode new biological functions?
  • Importance of Positioning for Microbial Evolution - Microbes commonly form dense communities that are central to many diseases and bioremediation. Here we demonstrate a simple and general principle of living in dense communities: microbes will commonly compete to reach nutrients at the community edge, akin to plants competing for light. Our work suggests that positioning is a major basis for evolutionary competition in dense microbial communities.
  • Biogeographic Patterns in Ocean Microbes Emerge in a Neutral Agent-Based Model - A key question in ecology and evolution is the relative role of natural selection and neutral evolution in producing biogeographic patterns. We quantify the role of neutral processes...The emergent patterns are substantial and suggest that microbes evolve faster than ocean currents can disperse them.
  • Epistatically Interacting Substitutions Are Enriched during Adaptive Protein Evolution - Mutations can fix during evolution for two reasons: they can be beneficial and fix for adaptive reasons, or they can be neutral or deleterious and fix solely by chance. Most studies focus on adaptation, where the evolving population is increasing in fitness due to a new selection pressure. Such studies have found an important evolutionary role for epistasis, the phenomenon where the effect of one mutation depends on another mutation. But adaptation only accounts for a fraction of overall evolutionary change. Here we investigate whether epistasis is as common during non-adaptive as adaptive evolution by comparing the same protein from human (under constant adaptive pressure) and swine influenza (under less adaptive pressure).
  • More bang for your buck: Quorum-sensing capabilities improve the efficacy of suicidal altruism - We use digital evolution (a form of experimental evolution that uses self-replicating computer programs as organisms) to investigate the effects of enabling altruistic organisms to communicate via quorum sensing. We found that quorum-sensing altruists killed a greater number of competitors per explosion, winning competitions against non-communicative altruists.
  • Global epistasis makes adaptation predictable despite sequence-level stochasticity - Epistatic interactions between mutations can make evolutionary trajectories contingent on the chance occurrence of initial mutations. We used experimental evolution in Saccharomyces cerevisiae to quantify this contingency, finding differences in adaptability among 64 closely related genotypes. Despite these differences, sequencing of 104 evolved clones showed that initial genotype did not constrain future mutational trajectories. Instead, reconstructed combinations of mutations revealed a pattern of diminishing-returns epistasis: Beneficial mutations have consistently smaller effects in fitter backgrounds. Taken together, these results show that beneficial mutations affecting a variety of biological processes are globally coupled; they interact strongly, but only through their combined effect on fitness. As a consequence, fitness evolution follows a predictable trajectory even though sequence-level adaptation is stochastic.
  • Pervasive domestication of defective prophages by bacteria - Several molecular systems with important adaptive roles have originated from the domestication of integrated phages (prophages). However, the evolutionary mechanisms and extent of prophage domestication remain poorly understood. In this work, we detected several hundred prophages originating from common integration events and described their dynamics of degradation within their hosts. Surprisingly, we observed strong conservation of the sequence of most vertically inherited prophages, including selection for genes encoding phage-specific functions. These results suggest pervasive domestication of parasites by the bacterial hosts. Because prophages account for a large fraction of bacterial genomes, phage domestication may drive bacterial adaptation.
  • Engineering microbial consortia: a new frontier in synthetic biology - Microbial consortia are ubiquitous in nature and are implicated in processes of great importance to humans, from environmental remediation and wastewater treatment to assistance in food digestion. Synthetic biologists are honing their ability to program the behavior of individual microbial populations, forcing the microbes to focus on specific applications, such as the production of drugs and fuels. Given that microbial consortia can perform even more complicated tasks and endure more changeable environments than monocultures can, they represent an important new frontier for synthetic biology. Here, we review recent efforts to engineer synthetic microbial consortia, and we suggest future applications.
  • Epistasis between adaptive mutations in hemoglobin - Two populations of deer mice – high and low elevation – differ in hemoglobin by 12aa in three clusters. Mix ‘n match of these three clusters show epistasis in O2-binding ability.
  • Social punishment of dishonest signallers - Paper wasp facial patterning is a signal of aggression. Signal can be manipulated with paint, trait with hormones. Four groups with ~20 pairs each: control, added paint (signal more aggression), added hormone (actually more aggressive), added both. Fig 2 shows that "added paint" group received more aggressive acts than any other. This implies social punishment when signal is higher than trait.
  • Adaptive valley crossing & recombination - Models genome structure as 4 loci: “abcd”. Uses two recombination rates, one within a “gene” (between a & b, between c & d) and another between “genes” (between b & c). With sufficiently many valley-crossings needed (e.g., 50 genes with xy local peak and XY global peak), asex gets trapped on an occasional local peak, but sex allows all global peaks thanks to recombination (Fig1).
  • Multiple Fitness Peaks on the Adaptive Landscape Drive Adaptive Radiation in the Wild. - The authors experimentally measure a fitness landscape in populations of wild pupfishes. They relate their findings to the populations' adaptive radiations and their tendency towards ecological generalism.
  • Explaining microbial genomic diversity in light of evolutionary ecology. - Review paper that suggests that much of microbial genetic diversity is due to social and ecological interactions. Population structure, niches, social cheating, quorum sensing are all talked about in this nicely written and easy to follow paper.
  • The winnowing: establishing the squid–vibrio symbiosis. - Really fun review paper that covers everything you wanted to know about the squid-vibrio symbiosis.
  • Genetic information transfer promotes cooperation in bacteria. -Talks about how horizontal gene transfer can favor cooperation. Authors compare structured and well-mixed environments to better understand the prevalence of cooperative genes on mobile elements.
  • A shift from magnitude to sign epistasis during adaptive evolution of a bacterial social trait.- Authors look at how epistatic interactions evolve in real time in specific biological systems. They characterize how the epistatic fitness relationship between a social gene and an adapting genome changes radically over a short evolutionary time frame in the social bacterium Myxococcus xanthus.
  • Feedback between Population and Evolutionary Dynamics Determines the Fate of Social Microbial Population- Authors demonstrate a coupling between population dynamics and the evolutionary dynamics of a “social” microbial gene, SUC2, in laboratory yeast populations whose cooperative growth is mediated by the SUC2 gene.
  • The evolution of plasmid-carried antibiotic resistance
  • Niche engineering demonstrates a latent capacity for fungal-algal mutualism
