|a The study of the mechanisms affecting single stress factor impact on long-term metabolic rearrangements is necessary for understanding the principles of plant protective reactions. The objective of the study was to assess the involvement of UV-C-induced genomic instability in induction рlant long-term protective reactions. The study was carried out on two genotypes of chamomile, Perlyna Lisostepu (PL) variety and its mutant, using UV-C pre-sowing seed radiation exposure at dose levels 5-15 kJ/m2. Multiple DNA damages under different exposure doses were studied on plant tissues during the flowering stage using - ISSR-RAPD DNA marker PCR. In the cluster analysis of changes within the amplicon spectra as an integral group the Jacquard similarity index was used. The results of the study suggest that genomic instability is a link between the direct effects of UV-C exposure and stimulation of metabolic rearrangements at the final stages of ontogeny. A hypothetical scheme for the transformation of primary UV-C DNA damage into long-term maintenance of genomic instability signs has been proposed
