Using the FISH method and PCR analysis, the presence of canonical P element was studied in the genomes of a number of laboratory lines isolated from nature in different years from the Zaprionus genus (Z. indianus) and Drosophila genus, Sophophora subgenus (D. ananassae, D. eugracilis, D. simulans, D. immigrans), Drosophila subgenus (D. virilis, D. mercatorum, D. hydei, D. funebris, D. pseudoobscura), Lordiphosa subgenus (L. magnipectinata), and Dorsilopha subgenus (D. busckii) in a search for new cases of horizontal transfer. According to our data, the L. magnipectinata genome contains sequences homologous to terminal regions of canonical P element, as well as the sequence with a weak homology from the central part of canonical P element. The P-element hybridization sites adjacent to the chromocenter were found in the D. pseudoobscura genome; this can indicate an ancient origin of the sequences homologous to the P element. The P element is absent in old D. simulans lines, except for the line isolated from nature in 2014 (in which the P element was found); this confirms data of other researchers about recent cases of horizontal P-element transfer in this species. No new cases of horizontal transfer were detected in the analyzed lines.
