In Silico Experimental Evolution Highlights the Influence of Environmental Seasonality on Bacterial Diversification [PDF]
, 2016 International audienceExperimental evolution, where fast replicating organisms are evolved in controlled environments for thousands of generations, has shown that microorganisms are able to evolve at an amazing speed: in virtually all experimental ...

Experimental Evolution of Interference Competition [PDF]
Frontiers in Microbiology, 2021 The importance of interference competition, where individuals compete through antagonistic traits such as the production of toxins, has long been recognized by ecologists, yet understanding how these types of interactions evolve remains limited. Toxin production is thought to be beneficial when competing with a competitor.

Experimental evolution of multicellularity [PDF]
Proceedings of the National Academy of Sciences, 2012 Multicellularity was one of the most significant innovations in the history of life, but its initial evolution remains poorly understood. Using experimental evolution, we show that key steps in this transition could have occurred quickly. We subjected the unicellular yeast Saccharomyces cerevisiae

Genetic Polymorphism Drives Susceptibility Between Bacteria and Bacteriophages
Frontiers in Microbiology, 2021 Phage therapy has attracted much attention for the treatment of antibiotic-resistant bacteria in recent years. However, it is common for bacteria to obtain resistance capability in short time after interaction with a lytic phage, as observed in phage ...

Heredity, 2008 This chapter reviews experimental evolution. Many of the evolutionary processes extend over long periods of time—long, that is, on human timescales of a few decades. With the resource of a laboratory, we can follow the evolution of large populations over thousands of generations in a few months.

Escherichia coli with a Tunable Point Mutation Rate for Evolution Experiments
G3: Genes, Genomes, Genetics, 2020 The mutation rate and mutations’ effects on fitness are crucial to evolution. Mutation rates are under selection due to linkage between mutation rate modifiers and mutations’ effects on fitness.

Experimental Evolution of Species Recognition [PDF]
Current Biology, 2015 Sex with another species can be disastrous, especially for organisms that mate only once, like yeast. Courtship signals, including pheromones, often differ between species and can provide a basis for distinguishing between reproductively compatible and incompatible partners.

A novel decoy strategy for polymyxin resistance in Acinetobacter baumannii
eLife, 2021 Modification of the outer membrane charge by a polymyxin B (PMB)-induced PmrAB two-component system appears to be a dominant phenomenon in PMB-resistant Acinetobacter baumannii.

Experimental evolution with yeast [PDF]
FEMS Yeast Research, 2006 Many of the difficulties of studying evolution in action can be surmounted using populations of microorganisms, such as yeast. A readily manipulated sexual system and an increasingly sophisticated array of molecular and genomic tools uniquely qualify Saccharomyces cerevisiae as an experimental subject.
