Sexual recombination and increased mutation rate expedite evolution of Escherichia coli in varied fitness landscapes.

Abstract excerpt

Sexual recombination and mutation rate are theorized to play different roles in adaptive evolution depending on the fitness landscape; however, direct experimental support is limited. Here we examine how these factors affect the rate of adaptation utilizing a "genderless" strain of Escherichia coli capable of continuous in situ sexual recombination. The results show that the populations with increased mutation...
