Localized sex in bacteria

Nature. 1991 Jan 3;349(6304):29-31. doi: 10.1038/349029a0.

Abstract

Electrophoretic studies suggest that bacterial populations consist of a number of independent clones and that genetic recombination is rare in nature. But DNA sequencing reveals that individual bacterial genes have a mosaic structure that could have arisen only by recombination. How can these observations be reconciled and what is their relevance to prokaryotic evolution?
