Abstract

Along the way, the mutagenic mechanism of lowenergy ions irradiation is a debatable issue. Recently, the existence of radiation induced longrange (mutagenic) effects in vivo in plants has been performed in a series of studies of our group, which account for the mutagenesis of lowenergy ions irradiation in a new perspective. However, numerous distinct biology phenomena remain to be addressed, which bear obvious characteristics to epigenetic. In the present study, using the expression of methylationrelated AtDML3 gene and methylation level of specific gene segments as end points, the methylation of cytosine, the most important feature of epigenetic, was investigated. It was shown that, in A. thaliana, rootloca lized αirradiation could induce epigenetic changes in aerial parts which avoided the direct irradiation. The radiation induced longrange epigenetic changes were confirmed in this study, which supplied innovative ideas for the further investigation of the mutagenetic mechanism of lowenergy ions irradiation.
