Spontaneous mutation in stationary-phase Escherichia coli WP2 carrying various DNA repair alleles.

Mutation research - 1 Jul 1993

Bridges B A

Abstract excerpt

Escherichia coli WP2 trpE65(ochre), when grown to stationary phase and plated on glucose salts medium, gave rise to slow growing tryptophan-independent mutants which formed increasing numbers of visible colonies from about day 6 onwards. These mutants were neither revertants at the ochre codon nor mutants at the tRNA suppressor loci normally found in this strain with logarithmic phase mutagenesis. The yield of...
