Summary: This study investigated the effects of selenium application on various aspects of peanut plants, including photosynthetic pigments, oxidant metabolism, flavonoids biosynthesis, nodulation, and agronomic traits. The results showed that selenium fertilization increased the concentration of photosynthetic pigments, activity of antioxidant enzymes, as well as growth and yield of peanut plants. It also improved nitrogen assimilation efficiency and promoted the synthesis of certain compounds in the roots, leading to increased nodulation and transportation of nutrients to the leaves.

Summary: Reactive nitrogen species (RNS) play important roles in male reproduction, but excessive levels can impair fertility by affecting testicular functions and compromising semen quality. High RNS levels lead to abnormalities in germ cells and gametes, and severely impact maturation and fertilization processes. Conventional semen analyses are not reliable predictors for assisted reproductive technology outcomes in cases of male infertility, highlighting the need for novel assessment and treatment methods.

Summary: Three slow-growing rhizobial strains isolated from cultivated peanuts in central China were characterized as a novel species named Bradyrhizobium zhengyangense sp. nov. based on their genotypic and phenotypic features. The strains were assigned to the genus Bradyrhizobium through phylogenetic analysis of their 16S rRNA sequences and further placed into a distinct lineage based on their concatenated gene sequences. Whole-genome average nucleotide identity analysis and digital DNA-DNA hybridization values supported their classification as a novel species.

Summary: Reactive oxygen species (ROS) are produced in mitochondria and play a crucial role in regulating the ovarian cycle through signaling. However, an imbalance between ROS generation and the antioxidant defense system can lead to ovarian diseases. Understanding the mechanisms of ROS generation and homeostasis in the ovary, as well as the pathological effects and potential antioxidant strategies, is important for the development of effective treatments.

Summary: Atmospheric pressure cold plasma (APCP) has great potential in improving crop production. This study investigates the regulation mechanism of APCP-generated reactive oxygen and nitrogen species (RONS) on intracellular redox homeostasis and plant growth. The results demonstrate that APCP treatment has a dual effect on Arabidopsis seedling growth, depending on the treatment time. APCP treatment leads to an increase in RONS in the liquid, conductivity, and oxidation reduction potential, and a decrease in pH. APCP treatment also causes an enrichment of intracellular RONS and an increase in malondialdehyde generation. Low-dose APCP treatment enhances intracellular antioxidants while high doses decrease their levels. These results highlight the importance of improved antioxidant capacity induced by moderate APCP-generated RONS in promoting plant growth.

Summary: Arsenic (As) accumulation in the food chain has raised global concern. This study investigated the role of the antioxidant system, particularly glutathione (GSH) metabolism, in peanut roots inoculated with Bradyrhizobium sp. strains showing varying tolerance to arsenic (As). Results showed that the strain modulated the activity of arsenate reductase (AR) differently and affected several enzymatic activities and gene expressions related to the antioxidant system. It was concluded that glutathione plays a fundamental role in metalloid detoxification and can serve as a biomarker of arsenic contamination in crops.

Summary: Plants in nature often encounter combined stress scenarios, and their response to such stresses can be unpredictable. This study investigated the metabolomic acclimation of sugar beet roots under the combined stress of salinity, heat, and high light. The results showed that high salt and high temperature significantly decreased the amounts of certain metabolites, while the combination of high light and high salt led to a decline in specific metabolite contents. These findings highlight the complex interaction patterns of environmental factors and emphasize the importance of studying combinatorial stress effects.
