title: [Fractionated UV-C irradiation effects on the changes of transcribed and satellite DNA methylation profile and unstable chromosomal aberration yield].
abstract: Interaction between changes of functionally different DNA methylation pattern and chromosomal aberration yield under fractionated UV-C exposure at the doses-of 6.2-9 kJ/m2 have been investigated. Two ways of meristematic tissue renewal after irradiation have been revealed on the grounds of statistical analysis. To estimate changes in the methylation pattern of transcribed and satellite DNA the restriction analysis was carried out. The restriction reaction was followed by PCR with ITS1(19b), ITS4(20b) and ISSR(14b) primers. The obtained data indicate specific changes in the methylation pattern of transcribed and satellite DNA parts under fractionated irradiation with different fraction ranges. Possible role of these changes in the progressing irradiation damage and inducible protection reactions is discussed.
