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.

Article Synopsis
- A study examined how chronic radiation exposure from the Chernobyl disaster affects phytohormone levels and related gene expression in Scots pine.
- Samples were taken from areas with varying radioactive contamination and analyzed for specific plant hormones and radionuclide activity.
- Results showed that radiation led to reduced levels of certain hormones, altered gene expression related to stress responses, and suggested adaptations in the trees to cope with radiation stress.

Green organisms evolve oxygen (O) via photosynthesis and consume it by respiration. Generally, net O consumption only becomes dominant when photosynthesis is suppressed at night. Here, we show that green thylakoid membranes of Scots pine (Pinus sylvestris L) and Norway spruce (Picea abies) needles display strong O consumption even in the presence of light when extremely low temperatures coincide with high solar irradiation during early spring (ES).

Article Synopsis
- The study investigates the effects of gamma radiation on three plant species: Norway spruce, Scots pine, and Arabidopsis thaliana, revealing that conifers are more sensitive to radiation compared to the herbaceous A. thaliana.
- High doses of gamma radiation (≥40 mGy h) significantly inhibited growth in the conifers, causing visible damage and mortality, while A. thaliana only displayed delayed root development at much higher doses (≥100 mGy h) without significant damage.
- All species experienced dose-dependent DNA damage, but the conifers showed more persistent adverse effects at the cellular and organismal level, indicating a lower tolerance to DNA damage compared to Arabidopsis thaliana.
No evidence of a protective or cumulative negative effect of UV-B on growth inhibition induced by gamma radiation in Scots pine (Pinus sylvestris) seedlings.

Article Synopsis
- - A study examined how UV-B radiation affects Scots pine seedlings' tolerance to gamma radiation, focusing on whether previous UV-B exposure helps seedlings acclimatize to low-moderate gamma radiation levels.
- - Results showed that gamma radiation significantly harmed the seedlings by increasing reactive oxygen species, reducing shoot and root length, and causing DNA damage, regardless of whether they were pre-exposed to UV-B.
- - Ultimately, no protective effect of UV-B against gamma radiation was found; any negative effects of both types of radiation on growth and DNA damage persisted for weeks but began to reverse after eight months.
