Summary: In this study, marigold flavonoids (MF) extracted from defatted marigold were investigated for their production technology, composition and content, antioxidant activity in vitro or in vivo, and acute oral toxicity. The results showed that MF extracted by acetone/water (9:1, v/v) had a content of 90%. The main components of the extracted MF were quercetagetin (84.7%), 6-hydroxykahenol (5.0%), quercetin (0.86%), and patuletin (1.44%). In vitro antioxidant activity tests showed that MF had comparable antioxidant activity with green tea polyphenols (GTP) and quercetin, and superior hydroxyl radical scavenging ability compared to four other antioxidants. In vivo antioxidant activity tests demonstrated that MF significantly decreased malondialdehyde (MDA) levels and increased superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in liver tissues, indicating better antioxidant activity than quercetin. Acute toxicity tests on rats and mice showed that MF had no toxic effects at a dose of 5000 mg/kg body weight. Therefore, MF can be considered a safe and potential antioxidant based on the experimental data in this paper.

Summary: Single-walled carbon nanotubes (SWCNTs) have shown promising applications in biomedicine, pharmacology, and precision agriculture. Our study revealed that SWCNTs have a concentration-dependent effect on photosynthesis, with lower doses being beneficial for plant growth, while higher doses may impair photosynthetic function. Therefore, SWCNTs could be a potential nanocarrier for substances beneficial for plant growth in the future.

Summary: The study found that Dittrichia viscosa leaves have a high accumulation capacity for antimony, and their photosynthetic efficiency remains unaffected. Increased antimony levels in leaves trigger a series of oxidative and reductive reactions, including increases in phenolics, carotenoids, and various enzymatic antioxidant systems. These responses may contribute to efficient detoxification of antimony.

Summary: Nanozymes with high catalytic performance are crucial for the construction of advanced biosensors for the detection and analysis of complex biological samples. In this study, FeS nanoparticles embedded in 2D carbon nanosheets (FeS@CNs) were demonstrated to have excellent catalytic activity as nanozymes. The introduction of a mesoporous carbon substrate effectively improved the enzymatic peroxidase-like activity of the embedded FeS nanozymes, especially in the fluorescence catalytic system. A facile method for H2O2 assay was designed based on the high peroxidase-like activity of the FeS@CNs nanozymes, with low detection limits for both colorimetric and fluorescence methods.

Summary: Salinity and drought are major stress factors for agricultural production in semi-arid regions. This study evaluated the effects of different levels of irrigation water salinity and water deficit on cabbage seedlings. The results showed that both factors caused significant losses in plant growth and increased stress-related parameters. Salinity and water stress also decreased photosynthetic activity. The best results were observed under certain combinations of salinity and water deficit levels. It was concluded that a 25% water deficit and irrigation water salinity exceeding 2.5 dS/m have adverse effects on cabbage plants in arid and semi-arid regions.

Summary: With increasing salinity levels, the germination percentage, seedling vigor index, fresh and dry weights of radicle and plumule, tissue water content, dry matter, photosynthetic pigments, and alpha-amylase activity of medicinal pumpkin seeds were decreased. However, these traits were higher in seeds pre-treated with putrescine. Additionally, under salinity stress, mean germination time, proline, and malondialdehyde contents increased, while seed priming with putrescine reduced them, indicating the potential of putrescine in improving seedling growth under salinity stress.

Summary: This study investigated the impact of biofertilizers and superabsorbent polymer (SAP) on the growth and essential oil composition of Ocimum ciliatum. The results showed that biofertilizers and SAP significantly increased the biomass and nitrogen and sulfur content of the plant. While the essential oil content was not affected, the treatments altered the proportions of essential oil constituents and induced the synthesis of new constituents. The main compounds in all oil samples were aromatic compounds (methyl chavicol) and oxygenated monoterpenes (citral). Nitrogen-fixing bacteria also changed the chemotype of the essential oil.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
