  • Title: [Induction of transposon Tn1 translocations as affected by different mutagens].
    Author: Kubaneĭshvili MG, Smirnov SP, Tarasov VA.
    Journal: Genetika; 1983 Jun; 19(6):903-11. PubMed ID: 6309610.
    Abstract:
    Transposition of ampicillin Tn1 transposon is repressed under normal conditions and occurs with low frequency (10(-4) per cell). Treatment of Escherichia coli cells with 22 c+mytomycin C, nitrosoguanidine and UV light induced transposition of Tn1 into different replicons. The degree of induction depended upon the strain of bacteria and the replicon which the transposon was inserted into. Mutation recA did not influence spontaneous translocation of the transposon but fully repressed induction of transposition during the period of mutagen treatment. In the present paper, the connection of inducible transposition process with the recA and lexA inducible functions of E. coli is discussed.
