Summary: Oxidative stress and hormonal regulation are key responses to biotic and abiotic stress in plants. Photo-oxidative stress markers and stress-related phytohormones can serve as effective predictors of mortality risk in long-lived species like Plantago lanceolata. Reduced photoprotective capacity in non-native populations was found to increase mortality risk, while the native population exhibited lower mortality rates.

Summary: The stomach acts as a bioreactor and plays a crucial role in biochemical reactions that impact human health. The oxidation of meat lipids in the stomach generates malondialdehyde (MDA), which is then absorbed into the bloodstream and modifies low-density lipoprotein (LDL) to MDA-LDL. The study found that vitamin E exhibits strong antioxidant activity against meat lipid oxidation in the stomach, especially at pH 3.0. The antioxidant activity of vitamin E at pH 3.0 is 20 times higher than that of catechin. Additionally, when combined with metmyoglobin (MbFe(+3)), vitamin E acts synergistically as a peroxidase/antioxidant couple, surpassing the antioxidant effect achieved by MbFe(+3)/catechin 150-fold. The continuous addition of low concentrations of vitamin E, catechin, and vitamin C helps maintain the meat's antioxidant activity, preventing lipid oxidation, reactive aldehyde generation, and loss of vitamin E.

Summary: This study explores the role of vitamin E in protecting seagrass leaves and rhizomes from damage under low temperature conditions. It found that adjustments in antenna size and vitamin E content help protect leaves from sustained photo-inhibitory damage and lipid peroxidation events. Rhizomes also accumulate some vitamin E and are protected from lipid peroxidation during winter. Cold stress can cause transient photo-inhibition in the photosynthetic apparatus of the seagrass.

Summary: During the postpartum period in cattle, there is an increase in non-esterified fatty acids (NEFA) in both serum and follicular fluid (FF), leading to the production of reactive oxygen species (ROS) that can affect fertility. This study aimed to characterize the lipid profile in FF of cows experiencing negative energy balance (NEB) and evaluate the effect of α-tocopherol in preventing oxidative stress in serum and FF. Fasting caused fat mobilization in cows and resulted in increased serum concentration of C18:1c9, which was also reflected in the FF. α-tocopherol concentration was higher in control and fasting + VitE groups, and there was an increase in FF α-tocopherol in the fasting + VitE group compared to fasting cows. ROS production was higher in fasting cows' serum and FF, with the fasting + VitE group showing lower ROS production in FF.

Summary: Olive trees shed their leaves as a defense mechanism under severe drought conditions. This shedding process, called abscission, is controlled through the accumulation of oxylipins and phytohormones, such as jasmonoyl-isoleucine and salicylic acid. Prolonged drought stress leads to a reduction in the efficiency of photosystem II, chlorophyll and vitamin E contents, as well as an increase in lipid peroxidation and oxidative stress.

Summary: This study investigated the content and composition changes of vitamin E in grape berries and leaves. It was found that the vitamin E content in leaves was higher than in fruits, with rich α-tocopherol in the skin and tocotrienols present only in seeds. During fruit ripening, the content of α-tocopherol decreased accompanied by an increase in lipid peroxidation. The changes in lipid peroxidation were negatively related to the variations in α-tocopherol content during fruit ripening.

Summary: Water shortage in crop irrigation is decreasing global agricultural production. Using sewage treatment plant (STP) water to irrigate horticultural fields is a solution to avoid using drinkable water in agriculture. In this study, two genotypes of pepper were irrigated with STP water and a biostimulant molecule was tested to improve fruit quality and production. Results showed that the genotypes differed in their tolerance to oxidative stress, but the use of STP water reduced commercial weight and ascorbic acid in peppers. However, the application of the biostimulant alleviated the negative effects of STP watering and improved fruit quality. These findings are important for overcoming water deficiencies in agriculture and promoting sustainable practices.
