Genetic and epigenetic changes were investigated in chronically irradiated Scots pine (Pinus sylvestris L.) populations from territories that were heavily contaminated by radionuclides as result of the Chernobyl Nuclear Power Plant accident. In comparison to the reference site, the genetic diversity revealed by electrophoretic mobility of AFLPs was found to be significantly higher at the radioactively contaminated areas. In addition, the genome of pine trees was significantly hypermethylated at 4 of the 7 affected sites.

慢性辐射作为生态因素：辐照的苏格兰松树种群中的甲基化过度和遗传分化

在切尔诺贝利核电站事故造成的受放射性核素严重污染的地区，对长期受辐射的苏格兰松（Pinus sylvestris L.）种群进行了遗传和表观遗传学研究。与参考位点相比，AFLPs电泳迁移率揭示的遗传多样性在放射性污染区明显更高。此外，松树的基因组在7个受感染部位中的4个处显着超甲基化。
