[Transduction as one of the methods of obtaining genetic information in Erwinia]
Abstract:
Transduction is one of the key processes of horizontal transfer of genes in bacteria. It is known that it is involved in distribution of the main factors of pathogenicity among numerous enterobacteria. It is shown that clear mutants and some variants of the temperate bacteriophage ZF40 Erwinia carotovora subsp. carotovora can perform general transduction of chromosome and plasmid genes of the bacterium E. carotovora. The indicators of chromosome transduction frequencies of the markers--arg+, met+, trp+, ura+ have a broad range of values: 7.10-10(-8) - 1.1-10(-1). The authors have succeeded in increasing the transduction efficiency due to infecting the recipient bacteria on the solid medium LB. Such approach is important for the phages similar to ZF40 in which adsorption is accompanied by re-adsorption of phage particles. The mechanism of transfer of bacterial genes by the type of general transduction is connected with cyclic permutation of phage DNA.
