  • Title: [Independence of the processes of transposition and genome rearrangements induced by transposons].
    Author: Nechaeva EV, Il'ina TS, Smirnov GB.
    Journal: Genetika; 1983 Mar; 19(3):388-96. PubMed ID: 6303900.
    Abstract:
    The data on the influence of the tnm mutations affecting transposition process on the deletion formation promoted by Tn and IS elements are presented. It was shown that the tnm mutations did not affect the frequency of deletion formation. The results of genetic analysis of the tnm mutant deficient in both transposition and genomic rearrangements induced by Tn9 inserted into lambda prophage, indicated that the mutant phenotype was caused by two different but linked mutations. A mutation affecting the process of genomic rearrangements was designated gerA2. The gerA2 mutation decreased sharply the frequency of rearrangements promoted by Tn9, Tn10 or Tn601 inserted into lambda prophage. However, this mutation had no influence upon transposition of the same Tn elements. The data obtained could be interpreted as indicating the independence of the processes of transposition and genomic rearrangements or as indication of the existence of specific steps of these processes.
