Evidence for selection in response to radiation exposure: Pinus sylvestris in the Chernobyl exclusion zone.

摘要: Changes of genetic structures due to viability selection are likely occur in populations exposed rapidly and extremely changing environmental conditions after catastrophic events. However, very little is known about the extent selective responses particular proportion genome involved putatively adaptive reactions for non-model plants. We used amplified fragment length polymorphisms (AFLPs) order investigate differences between pine (Pinus sylvestris) trees which were partially extreme conditions. Genetic variation patterns pines high radiation Chernobyl exclusion zone with or without phenotypic stress symptoms compared control a similar origin. Six percent investigated loci (15 222 loci) identified as candidates responses. Moderate differentiation was observed groups showing either weak strong levels.
