Corn plant DNA methylation pattern changes at UV- C irradiation fractionating


The relationship between changes in the methylation pattern of functionally different parts of DNA and the chromosomal aberration’s yield was studied under the conditions of UV-C irradiation fractionating. A combination of restriction analysis (HpaII, MspI, and MboI enzymes) with subsequent PCR (internal transcribed spacer ITS1 and ITS4 and inter simple sequence repeat ISSR(14b) primers) was used. The obtained results showed changes in the methylation pattern of the satellite and transcribed DNA part of DNA at irradiation in the fractionating mode, depending on the fraction range. The role of a DNA methylation pattern changes in the development of radiation damage and induction of the organism’ protective reactions was discussed.
