| Research Abstract |
Mutualism is ubiquitous in nature, and its establishment and evolution are important issues in ecology. To understand how organisms adapt to the first encounter with another organism to establish and evolve mutualism, experimental reconstruction of these processes is a useful strategy. Previously, we experimentally simulated the establishment of mutualism using two genetically-engineered auxotrophic strains of Escherichia coli, and found that one strain rapidly changed its phenotype, eventually leading to the establishment of the mutualism. Here we show not only the molecular basis of the observed phenotypic change, but also the experimental evolution of this mutualism.
