  • Title: [Erwinia carotovora as a recipient system for the natural hybrid plasmid RP4::Mu cts62].
    Author: Danileĭchenko VV, Britskaia VS, Il'iashenko BN.
    Journal: Mol Gen Mikrobiol Virusol; 1990 Sep; (9):23-6. PubMed ID: 2175013.
    Abstract:
    The plasmid RP4::Mu cts62 is transferred from Escherichia coli cells into a recipient strain Erwinia carotovora 268 by conjugation with the frequency 1.5-5 x 10(-7) per donor cell. The maximal frequencies of transfer are obtained by cultivation of donor and recipient cells for 3-5 h on the filters. Structural and functional validity of the plasmid in transconjugants is expressed in preservation of all antibiotic-resistant markers of RP4, thermosensitivity to growth at 42 degrees C as well as spontaneous and thermally-induced production and zygotic induction of bacteriophage determined by the genome of Mu cts62, total length of the plasmid restricts. Location and orientation of Mu cts62 genome in the plasmid restricts. Location and orientation of Mu cts62 genome in the plasmid RP4::Mu cts62 in Erwinia carotovora transconjugant cells has been determined. A single bacteriophage genome has been shown to transpose into the chromosome of the cell with the elimination of RP4 fragment under the conditions of thermal induction.
