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.
The pollen quality of woody and herbaceous plants from the Chernobyl exclusion zone.

Pollen abnormalities frequency of Scots pine and pollen sterility of white clover, common columbine, and greater celandine growing in the Bryansk and Gomel' regions radioactively contaminated after the accident at the Chernobyl nuclear power plant (NPP) were assessed. The frequency of abnormal pine pollen at the most contaminated plots significantly exceeded the control level and positively correlated with the total absorbed dose and the absorbed dose from β-radiation. No sustainable significant changes in pollen sterility of the herbaceous plants studied were found in the exclusion zone of the Chernobyl NPP.

Article Synopsis
- - The study focuses on developing crop adaptation strategies in response to climate change, specifically through investigating barley's reaction to ionizing radiation as a means to understand stress resilience.
- - Researchers identified 553 genes that were upregulated and 124 downregulated in barley seedlings after exposure to different types of radiation, with the highest activity seen in samples exposed to electrons.
- - Key genes relating to stress responses, such as those involved in DNA repair, ROS response, and photosynthesis, were significantly activated, suggesting that understanding these pathways could enhance plant stress tolerance in agriculture.
Adaptation to environmental stressors is an essential property of plants that allows them, despite an immobile lifestyle, to survive in a changeable environment. The chain of successive events culminating in the final radiobiological reaction begins with the absorption of energy of ionizing radiation in the cell. Starting from stochastic acts of molecular injury formation, radiation damage gradually acquires deterministic features, which are expressed in a limited number of phenomena that complete plant radiation damage.
