The viability index (%) of experimental potato plants-regenerants grown on the invasive background on nutrient media with bioregulators was found to be increased to 54-79 %, compared with control plants, among which the number of viable plants was 39 %. The degree of damage of the total leaf and stem surface in plants obtained on nutrient media with bioregulators is shown to be reduced to 31–48 %, compared to increase to 67 % degree of damage of control plants-regenerants. The dot-blot hybridization method showed the decrease to 36 – 65 % in the index of the hybrid cytoplasmic mRNA and si/miRNA molecules, isolated from cells of control and experimental potato plants-regenerants, grown under in vitro conditions on the artificial invasive background on nutrient media with bioregulators, compared with the same index of control plants. The experiments conducted under in vitro cell-free system of protein synthesis from wheat seedlings showed an increase in the silencing activity to 31 – 59 % on the template of plant mRNA of si/miRNA isolated from cells of experimental potato plants-regenerants, grown under in vitro conditions on the artificial invasive background on nutrient media with bioregulators, compared with activity of cytoplasmic si/miRNAs isolated from control potato plants-regenerants.
