چکیده انگلیسی
Transposons closely related to mercury resistance transposons Tn5041, Tn5053, and Tn5056, which have been previously described in present-day bacteria, were detected in a survey of 12 mercury-resistant Pseudomonas strains isolated from permafrost samples aged 15-40 thousand years. In addition, Tn5042, a novel type of mercury resistance transposon, was revealed in the permafrost strain collection and its variants found to be common among present-day bacteria. The results reveal that no drastic changes in the distribution mode of the different types of mercury resistance transposons among environmental bacteria have taken place in the last 15-40 thousand years.
