Electromagnetic radiation of the radiofrequency waveband is the new antropogenic factor of the environment and research into its influence on the living organisms is of great interest. The radioprotective action of mm waves on plant cells, the embryo meristem of Hordeum L., Triticale-wittmarc, Secale L. and other sprouting seeds has been investigated. In compliance with literature data and the authors' results the mechanism of mm waves action and the formation of radioadaptive response have a complex character and is due to both the activation and the inhibition of gene expression, the functions of the energy provision systems of cell membranes, the processes of reparation and transcription, the regulation of events in the mitotic cycle. The reaction of plant cells depend on the genotype, the physiological state of subject, the time and condition after the irradiation. |
