[Spontaneous reversion of polA1 mutation on a mutant strain of E. coli K12 by transfer of ColE1 plasmid].
Specific polA1 mutation prevented the expression of high mutability in the mutator strain, H2IIO polA1 Spontaneous revertant of H2IIpolA1 was isolated by the transfer of ColE1 plasmid onto the mutator mutant. This spontaneous revertant, H2IIOpol, regained the mutator phenotype.
