“…According to our data (Table , Table ), the irradiated seedlings show a transcriptional reprogramming of genes related to metabolites mobilization, which seems to be a less impacting alternative for obtaining energy than photosynthesis considering ROS production. Indeed, previous findings suggest that the modulation of ROS levels and probably of the photosynthesis rate are important for the control of the homoeostasis in response to chronic low‐dose radiation exposure (Duarte, Volkova, & Geras'kin, ).…”

At low intensity, certain stress conditions may have a positive effect on growth and development of plants (eustress). Growth stimulation of barley plants after gamma irradiation of seeds in low doses was observed as an increase in root and shoot lengths. Hydrogen peroxide concentrations in shoots of irradiated plants were significantly higher than in control, while the opposite effect was observed in the roots. To elucidate the molecular basis of growth stimulation after gamma irradiation of barley seeds, we performed the transcriptomic analysis of barley embryos at different stages of seed germination. The transcriptomic data were correlated with morphological parameters and the hydrogen peroxide levels in irradiated and control plants. These data indicate that the growth stimulation by low‐dose irradiation involves the transcriptional control of genes related to phytohormones, antioxidant system, late embryogenesis abundant proteins and cell wall components, with possible involvement of jasmonate and ABA signalling. Gamma irradiation of seeds at dose 100 Gy caused significant growth inhibition and promoted expression changes in transcripts related to cell cycle arrest, DNA damage repair and antioxidant system.

“…The mapping and bioinformatic analyses of gene expression are based on the most complete and high-quality reference transcriptome of P. sylvestris available to date (Ojeda et al 2019). Previous transcriptome studies of P. sylvestris have concentrated on a narrow set of tissues in each study such as wood (Paasela et al 2017), embryo (Merino et al 2016), and needles (Wachowiak et al 2015; Duarte et al 2019) or focused on a limited set of genes (Guseva et al 2020). The present study allows comparison across a wide set of genes expressed in the above-ground parts of adult P. sylvestris trees growing in a natural forest.…”

Background: Despite their ecological and economical importance, conifers still have limited genomic resources, mainly due to the large size and complexity of their genomes. In addition, several of the available genomic resources lack complete structural and functional annotation. Transcriptomic resources have been commonly used to compensate for these deficiencies, though for most conifer species the currently available transcriptomes are limited to a small number of tissues, or capture only a fraction of the genes present in the genome. Results: Here we provide an atlas of gene expression patterns for conifer Pinus sylvestris grown under natural conditions across five tissues: embryo, megagametophyte, needle, phloem, and vegetative bud. Compared to previous studies, we used a wider range of tissues and focused our analyses on the expression profiles of genes at tissue level. We provide comprehensive information of the per-tissue normalized expression level, and indication of tissue preferential upregulation or tissue preferential expression. We identified a total of 48,001 tissue preferentially upregulated and tissue specifically expressed genes, of which 28% have annotation in the Swiss-Prot database. The annotated genes were associated with a total of 84,498 GO terms, of which 1,834 had significant enrichment in different processes and functions, for example glyoxylate cycle in megagametophyte and defense response in needle. Even though most of the genes originating from the transcriptome do not have functional information in current biological databases, the tissue-specific patterns identified here provide valuable information about their potential functions for further studies. Conclusions: The genes identified in this study will contribute to improve the annotation of the already available and forthcoming conifer genomes. This atlas of gene expression also provides ground to further the research in the areas of plant physiology, population genetics, and genomics in general. As we provide information on tissue specificity at both diploid and haploid life stages, our data will also contribute to the understanding of evolutionary rates of different tissue types and ploidy levels.

“…Thus, radioactive contamination of natural areas is one of the longest-lasting anthropogenic impacts on the environment. Duarte et al (2019) have analyzed the de novo transcriptome of the Scottish pine population growing in the Chernobyl affected area, which is still contaminated with radionuclides due to the 1986 nuclear accident. Transcriptome profiles indicate a clear picture of the adaptive stress response, which seems to depend on the dose.…”

“…These adaptive reactions, which are caused by radiation doses 30 times lower than those recognized as safe for biota species under international standards, suggest that environmental management for radiation protection should be reviewed [2].…”

The situation with the processing and disposal of radioactive waste, including the liquid phase, is not resolved. Many questions remain regarding the environmental safety of processes and the technological implementation of the most energy-efficient solutions. Thus, the article’s main attention is paid to theoretical studies of the development innovation directions of radioactive waste processing using the VOSviewer software tool. The clusters were formed under modeling directions of application of radiolysis for radioactive waste utilization: the red cluster includes research of radionuclide sorption processes and their concentration for radiolysis of liquid media; the green cluster concerns factors of influence on water radiolysis in hydrogen production; the yellow cluster includes research areas of natural processes related to radiolysis; the blue cluster is connected with mathematical modeling of radiolysis process with fuel production and engineering implementation and the purple cluster related to the processes of radioactive waste management and disposal as well as the application of radiolysis for this purpose. The cluster simulations of nanoparticle and radiolysis applications for radioactive waste treatment have resulted in a new energy recovery strategy. The development of new matrix materials in combination with nanoparticles for the agglomeration and concentration of radionuclides is a promising innovative method of improving radiolysis under hydrogen production from radioactive waste. Keywords: radioactive waste, nanoparticle, radiolysis, cluster simulations, software tool.
