Long-term experimental evolution in Escherichia coli. XIII. Phylogenetic history of a balanced polymorphism.

Journal of molecular evolution - 1 Aug 2005

Rozen Daniel E, Schneider Dominique, Lenski Richard E

Abstract excerpt

We investigated the phylogenetic history of a balanced polymorphism that evolved in an experimental population of Escherichia coli. Previous work showed that two ecologically and morphologically distinct types, designated L (large) and S (small), arose by generation 6000 and coexisted for more than 12,000 generations thereafter. Here, we performed RFLP analyses using Insertion Sequence elements to resolve the...
