Evolution is expected to involve mutations that are small and modular in effect, but recent findings suggest that mutations early in an adaptive process can have strong and pleiotropic effects. This study uses experimental evolution in yeast to show that while first-step mutants appear pleiotropic in nature, second-step mutations show a shift towards modular adaptation.
Enhanced metabolic entanglement emerges during the evolution of an interkingdom microbial community

Here, the authors investigate the mechanisms behind mutualism with an engineered microbial community, finding that repeated indirect selection for enhanced metabolic dependencies may be a common factor in the evolution of mutualistic communities.
Our colleagues of the #EvolutionaryBiology group at #ETHZurich have just published https://www.myxoee.org/, a website on #myxobacteria #ExperimentalEvolution. Anyone interested in the evolution of sociality, cooperation and predation should have a look!

The goal is to study the evolutionary and plastic response of the transcriptome to stable vs fluctuating environments, in the model fungus Zymoseptoria tritici.
