Competition between isogenic mutS and mut+ populations of Escherichia coli K12 in continuously growing cultures

Mol Gen Genet. 1984;198(2):175-6. doi: 10.1007/BF00328719.

Abstract

Previous studies have shown that the mutT, mutH and mutL mutators of Escherichia coli have a marked advantage in competition growth with otherwise coisogenic wild-type strains. As shown in this paper the same is true for the mutS mismatch mutator. In three experiments mutS could outgrow the wild-type and had higher fitness values.
