Investigation of a Complex Phenotype in Escherichia coli K-12

[摘要] This study investigates the ability of Escherichia coli K-12 strains to utilize citrulline as a source of carbamoyl phosphate. One response of strains to this selection procedure is the amplification of the argF gene. This response had only previously been observed when the E. coli sex factor, F, was integrated adjacent to Tn2901, the transposon like structure that carries the argF gene. I demonstrate here that tandem amplification of Tn2901 can occur in an F strain after long incubation of the strain on selective medium at 30
