Genetic barriers among bacteria.

by I Matic, F Taddei, M Radman
Trends in Microbiology (1996)

Abstract

Barriers to chromosomal gene transfer between bacterial species control their genetic isolation. These barriers, such as different microhabitats, the host ranges of genetic exchange vectors and restriction-modification systems, limit gene exchange, but the major limitation is genomic sequence divergence. The mismatch-repair system inhibits interspecies recombination, the inducible SOS system stimulates interspecies recombination, while natural selection determines the effective recombination frequencies.
