Summary: This study investigates the mechanistic basis of Trigonelline (TG)’s photoprotective effect against UV-B-induced oxidative DNA damage. The results demonstrate that TG significantly alleviates cell death and DNA damage induced by UV-B by regulating the expression of key protein markers. TG also prevents UV-B-induced oxidative stress by activating the PI3K-AKT-Nrf2 signaling pathway. This study provides strong evidence for TG as a potential agent against UV-B-induced skin photodamage disorders.

Summary: The negative correlation between diets rich in fruits and vegetables and the occurrence of cardiovascular disease, stroke, cancer, and other deleterious conditions may be partly due to flavonoids and other polyphenols. Recent research suggests that the antioxidant role of polyphenols in food may be based on incomplete understanding, and that their actual mechanism may involve regulating cell signalling pathways. New findings show that food polyphenols and their metabolites act as effective antioxidants by significantly increasing the antioxidant protection of cells and tissues.

Summary: Light is essential for plants, but excessive light can be harmful. Plants have developed adaptations to protect themselves from harmful radiation, such as the production of secondary metabolites like flavonoids and carotenoids. Light regulates the accumulation of these metabolites through various molecular mechanisms. Understanding these mechanisms and using metabolic engineering can help enhance the production of beneficial metabolites and create climate-resilient plants. Optimum artificial lighting can also increase the production of these metabolites, which have nutritional and medicinal benefits.

Summary: The present study investigates the effects of individual and combined stress of chromium and ultraviolet-B radiation on Psoralea corylifolia. The results show that chromium and UV-B radiation have variable impacts on the plant's ultrastructure, physiology, and biomass. Combined treatment leads to higher antioxidant activity and lower oxidative damage.

Summary: The pathophysiology of schizophrenia is still not well understood. Genetic factors and oxidative stress play key roles in its development and progression. Oxidative stress leads to the continuous production of oxidation products, such as AGEs and AOPPs, which interact with their receptors, amplifying the production of reactive oxygen species (ROS) and pro-inflammatory cytokines. In this study, plasma levels of AGEs and AOPPs were found to be significantly higher in schizophrenia patients compared to controls, confirming their involvement in mental disorders. Antioxidant nutraceuticals and a healthy lifestyle could reduce oxidative stress and alleviate schizophrenia symptoms.

Summary: Subjects with Gilbert's syndrome show higher levels of antioxidant potential and protein oxidation products, as well as lower levels of apolipoprotein B, hs-C-reactive protein, interleukin 6, and interleukin 1 beta compared to healthy controls. Resting heart rate is also significantly lower in the GS group. Older subjects with GS demonstrate stronger protective effects.

Results showed that salt stress reduced growth parameters and photosynthetic pigments while increasing certain metabolites and antioxidant enzymes. Application of Wuxal amino improved morphological traits, photosynthetic pigments, and antioxidant enzymes activity in salt-stressed plants, reducing the deleterious impact of salinity.

Summary: Postharvest UV-B radiation can increase the contents of chlorophyll, carotenoid, soluble sugar, catalase (CAT) and superoxide dismutase (SOD) in honeysuckle leaves, while decreasing the malonaldehyde (MDA) content. The polysaccharide, total polyphenols, total flavonoid, and chlorogenic acid contents in different organs all increased significantly under specific UV-B treatments, showing a correlation with physiological traits.

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: This study cloned the full-length cDNA sequence of TaSPX3 gene in wheat and found that TaSPX3 responds to low phosphorus stress in multiple wheat genotypes. Overexpressing TaSPX3 can alleviate phosphorus deficiency symptoms and promote plant growth in Arabidopsis. The study also revealed the interaction of TaSPX3 with other genes related to the phosphorus starvation signaling pathway.

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.
