title: Chromosomal fragmentation is the major consequence of the rdgB defect in Escherichia coli.
abstract: The rdgB mutants depend on recombinational repair of double-strand breaks. To assess other consequences of rdgB inactivation in Escherichia coli, we isolated RdgB-dependent mutants. All transposon inserts making cells dependent on RdgB inactivate genes of double-strand break repair, indicating that chromosomal fragmentation is the major consequence of RdgB inactivation.
