Electromagnetic radiation of the radiofrequency waveband is the new anthropogenic factor of the environment and research into its influence on living organisms is of great interest. The modifications in nuclei content (DNA, RNA, protein) of seeds during growth after exposure by mm-waves (45-53 GHz) may be related to abnormal photosynthetic activity, as well as with plant transcriptome activity, which more visible by study modulation in the content of 5-mC DNA methylation. The part of investigated seedlings was growing in soil to get a harvest of second-generation. Obtained in our study data shows that the changes in the level of DNA methylation in the first generation of seeds during the plant ontogeny are conserved and partially pass to the seedlings of second-generation seeds.EPIGENETIC-EVENTS
