Summary: This study aimed to assess the impact of different planting sites on the oil quality of Moroccan rapeseed varieties. The results showed significant differences between the two sites for all parameters, with Allal Tazi outperforming Douyet. Variety and variety by site interaction had a significant effect on all parameters. The Moufida and Alia varieties maintained consistent high performance across both sites, making them genetically interesting for agricultural and nutritional purposes.

Summary: This study examines the impact of sensor-based irrigation schemes and three treatments (overwatered, optimal, and underwatered) on the growth and nutritional content of 'Winterbor' kale. The results show that overwatering and underwatering treatments result in smaller morphological features compared to optimal treatment. However, there is no significant difference between overwatering and underwatering treatments. In terms of mass, optimally treated plants have the greatest mass, while underwatered treatment has reduced mass but still greater than overwatered treatment. Concentrations of mineral nutrients, glucosinolates, and pigments change with gas exchange and chlorophyll fluorescence measurements, showing both temporal and treatment variations. Apparent nutritional content is significantly reduced for overwatering and underwatering treatments compared to optimal treatment, but underwatered treatment has little impact on secondary metabolites and mineral nutrients.

Summary: Thermal stress affects plant productivity and harvest quality. Plants activate protective metabolic pathways to adapt to different temperature ranges. This study found that stressful environments have an impact on the accumulation of glucosinolates (GSLs) in Brassicaceae plants. Higher GSL content increases resistance to cold, and cold conditions lead to the accumulation of indolic GSLs. High levels of GSLs, particularly glucobrassicin (GBS) and sinigrin (SIN), are found under cold temperatures. The results suggest that GSLs play a key role in cold tolerance, but the molecular mechanisms need further investigation.

Summary: Over-expression of BnPgb2 in Brassica napus increases the oil content without changing its nutritional value. It induces the expression of transcription factors LEC1 and WRI1, promoting fatty acid synthesis and oil accumulation. BnPgb2 also enhances sugar metabolism and starch synthesis, providing energy and carbon sources for fatty acid production.

Summary: Brassica oleracea var. acephala, known for its strong tolerance to low temperatures, contains health-promoting compounds such as polyphenols, carotenoids, and glucosinolates. This study suggests that glucosinolates are involved in protecting against low temperature stress, with different glucosinolate species likely contributing to different protective mechanisms.

Summary: In this study, extreme individuals from a broccoli F-2 population were selected and grouped into low and high glucoraphanin content pools of leaf, stalk, and floret. Transcriptome and metabolome analyses revealed significant differences in the expression of genes and accumulation of metabolites in the three plant parts. Certain genes showed different expression trends between low and high glucoraphanin content pools, and the accumulation of glucoraphanin upregulated the expression of plant hormone signal transduction-related genes and increased the levels of flavonoid metabolites. This study provides insights into glucosinolate biosynthesis in different organs and highlights the crosstalk between glucosinolates and flavonoids biosynthesis pathways.

Summary: This paper presents the outcomes of discussions on the importance of an ecosystem approach in radioecology and radiation protection of the environment, which took place at an international conference. The interaction between radioecologists and radiobiologists is vital for addressing the challenges of field versus laboratory research and the integration of a pan-ecosystem approach into radiation protection guidelines. The application of novel tools such as machine learning can aid in the development of this ecosystem approach.

Summary: The study reveals that exposure to gamma radiation can lead to DNA methylation changes in young Arabidopsis plants across multiple generations, with a significant increase in differentially methylated regions (DMRs) in the second generation exposed to the lowest dose rate. Surprisingly, there were no significant differences in plants exposed to the highest dose rate. Hypermethylation of transposable elements was found to increase genetic stability, while DMRs associated with genes were enriched for development and stress response-related functions, suggesting a role of DNA methylation in regulating gene expression in response to radiation.

Summary: The study presents the development of a set of consensus Adverse Outcome Pathways (AOPs) for reproductive effects of ionizing radiation in wildlife. It identifies key biological events and causal linkages between ionizing radiation, reproductive impairment, and reduction in population fitness. The AOPs have the potential to assist applications in radiation research, environmental health assessment, and radiological protection. Future plans include further advancement and consolidation of the AOPs through weight of evidence considerations and formal review by the OECD sponsored AOP development program.

Summary: Currently, the levels of ionizing radiation on Earth's surface are relatively low and do not pose significant challenges to the survival of contemporary life forms. This radiation can come from natural sources, the nuclear industry, medical applications, radiation disasters, or nuclear tests. This article discusses the effects of modern sources of radioactivity on different plant species and the protection of plants from radiation. It also explores the hypothesis that ionizing radiation may have played a role in limiting land colonization and plant diversification rates.

This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
