Clonal divergence in Escherichia coli as a result of recombination, not mutation.

Science (New York, N.Y.) - 25 Nov 1994

Guttman D S, Dykhuizen D E

Abstract excerpt

Nucleotide sequence analysis was performed on 12 natural isolates of Escherichia coli in four loci located in close proximity on the chromosome. A comparison of gene genealogies indicated that three recombination events have occurred in a subset of the strains (ECOR group A) in the time since their divergence from a common ancestor, while during the same time, no mutational divergence has occurred. The common...
