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.
The stimulation of growth and development of crops using ionising radiation (radiation hormesis) has been reported by many research groups. However, specific genes contributing to the radiation stimulation of plant growth are largely unknown. In this work, we studied the impact of the low-dose γ-irradiation of barley seeds on the growth dynamics and gene expression of eight barley cultivars in a greenhouse experiment.

In this work we studied the effect of Cd on growth, antioxidant enzyme activity, and phytohormonal status of four barley cultivars (cvs. Simfoniya, Mestnyj, Ca 220702, Malva).
