Summary: This study evaluated the effect of different NaCl concentrations on the growth stages, antioxidant enzyme activity, and stress indicator concentrations of Tripolium pannonicum. The results showed that different plant organs had varying adaptation mechanisms to salt stress, with leaves being more salt-tolerant. Salt stress increased antioxidant enzyme activity and stress indicator concentrations, and these mechanisms were dependent on the growth phase, organs, and duration of salt exposure.

Summary: This study investigated the changes in ROS and their scavenging systems during nectarine fruit development and ripening and found a complex reprogramming of ROS-related transcriptome and metabolome. The activation of specific ethylene response factors and the accumulation of antioxidant compounds were observed at earlier fruit developmental stages, while a decrease in respiration rate and reduction of ERF1 genes led to higher accumulation of H2O2 at later stages. The study suggests that H2O2 may not only be a by-product of ROS-scavenging but also a signaling molecule during nectarine fruit ripening.

Summary: This study investigates the role of the antioxidative system in salinity tolerance of two halophytes. The findings suggest that different mechanisms are employed by each plant to cope with salt stress, with variations in enzyme activities and gene expression. These findings contribute to the understanding of salinity tolerance and can be applied to improve salt tolerance in crops.

Summary: This study evaluated the forage yield and quality of river saltbush as affected by compost application in saline soil. Compost addition increased forage yield, crude protein content, and mineral content, while reducing Na+ and oxalate concentrations in the leaves. Compost also improved the activity of polyphenol oxidase and catalase, alleviating the negative effects of soil salinity and enhancing the growth of river saltbush plants, making them valuable as animal feed.

Summary: This study evaluated the performance of antioxidant systems in Hass avocados under refrigeration and controlled atmosphere conditions and their possible relationship with physiological disorders. The results showed that different enzymatic and non-enzymatic systems responded differently to oxidative stress during storage and shelf life. Physiological disorders were more likely to occur in refrigeration conditions compared to controlled atmosphere.

Summary: This study investigated the browning mechanism in fresh-cut eggplant using an untargeted metabolomics approach and physiology experiments. It was found that the content of chlorogenic acid may play a significant role in browning, and the activities of enzymes related to phenylpropanoid metabolism increased with prolonged cutting time. Additionally, the accumulation of ROS and changes in antioxidant enzyme activities were observed after cutting, providing insights into the browning process during fruit and vegetable processing.

Summary: Salinized land is spreading globally, threatening crop yields and the ability to feed a growing population. This review discusses the mechanisms of nano-enabled antioxidant enzyme-mediated plant tolerance to salt stress, including maintaining ROS homeostasis, enhancing ion retention and elimination, increasing nitric oxide production, signaling pathways, and reducing oxidative damage. Common techniques like protecting cells from oxidative stress and maintaining ionic balance are highlighted. The application and potential mechanisms of nanotechnology in salt tolerance of plants are also explored. The review aims to aid researchers in various fields to comprehend the potential of novel solutions for sustainable agriculture addressing salinity issues.

Summary: Oxidative stress can cause diseases, but antioxidants in foods can prevent diseases and delay aging. Phenolic compounds, such as flavonoids, are present in plants and contribute to the bitterness and color of foods. Dietary phenolic compounds exhibit antioxidant activity and can prevent cell aging and diseases. The structures of these compounds can be changed by intestinal bacteria metabolism, and the resulting metabolites exert effects in vivo.

Summary: The exogenous application of flavonoids can stimulate photosynthesis and promote plant growth. It can also increase stomatal opening, leading to enhanced water and nutrient uptake. The mechanism of action of flavonoids may be associated with phenolic metabolism and the expression of aquaporins.

Summary: Ice plant is a halophytic plant species, and little is known about its response to future ozone concentration. This study evaluated the effects of elevated O3 concentration, salinity, and their combination on various parameters of ice plant. The results showed that salinity played a crucial role in alleviating oxidative stress caused by elevated O3, emphasizing the importance of salt for the growth of this plant under combined stress.
