Summary: This study investigated the effects of lemon and lemongrass essential oils (EOs) on Botrytis cinerea using enzymatic and proteomic analyses. Both EOs showed scavenging activity and increased levels of malondialdehyde and superoxide dismutase in B. cinerea mycelia. Lemon EO contained d-limonene as a major constituent (71%), while lemongrass EO contained α-citral (50.1%). Proteomics analysis identified 42 proteins, including 13 unique proteins found only in lemon and lemongrass EO-treated B. cinerea.

Summary: The up-regulation of NADPH oxidase and endogenous H2O2 seems to be an early response to salinity in cucumber plants. Increasing salt concentration leads to elevated activity of NADPH oxidase and H2O2 levels, as well as the activation of antioxidant enzymes.

Summary: Recent studies have found that salicylic acid (SA) can reduce postharvest losses in various flower systems. This study focused on the role of SA in enhancing physiological and biochemical responses to mitigate postharvest senescence in cut spikes of Consolida ajacis. The results showed that SA treatment increased the postharvest longevity of the cut spikes, as well as the solution uptake, sugar, and protein content of the tepal tissues. SA also enhanced the antioxidant system and reduced lipoxygenase activity, preserving membrane integrity and preventing solute leakage from the tepal tissues.

Summary: This study explored the antioxidant activity of sorghum seeds collected from five countries and identified genetic resources with high antioxidant activity. The results showed that sorghum seeds contained high levels of total phenolic and flavonoid compounds. Several phenolic compounds were identified, with taxifolin being the most abundant. The expression levels of antioxidant genes were also analyzed, with some genetic resources showing higher expression levels. These findings indicate that sorghum can be considered as a biomaterial derived from natural resources.

Summary: This study developed an efficient detection method of penconazole based on ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and investigated the degradation behaviors of penconazole in apple fruit. The results showed that there was no significant difference in penconazole residue after 45 days when the residue was <= 0.2 mg/L. However, penconazole application induced stress, and bagging affected the activity of antioxidant enzymes in apple fruit.

Summary: Nanozymes, nanomaterials with enzyme-mimicking activity, have attracted significant interest in biomedical applications, particularly in oxidative stress-mediated disorders. The challenge lies in designing nanozymes that can selectively differentiate between physiological oxidative stress and pathological oxidative stress and mediate appropriate redox reactions in cells, tissues, and organs. This review summarizes the advancements in redox-active nanozymes and their therapeutic significance in various disease models, such as cancer, neurodegeneration, and cardiovascular diseases. It also discusses the future prospects and challenges associated with the biomedical applications of nanozymes.

Summary: The study found that while sun leaves have higher photosynthetic capacity, they are subject to photoinhibition, resulting in lower chlorophyll pigment content and chlorophyll carotenoid ratio. The plant responds to increased photosynthetically active radiation by increasing the activity of ascorbate peroxidase to mitigate reactive oxygen species.

Summary: Postharvest diseases are a major concern for table grapes, causing significant economic losses worldwide. Traditional methods for disease detection have limitations in accurately identifying asymptomatic diseases, while proteomics offers instantaneous results for early detection. This review provides an overview of postharvest disease pathogens and symptoms in table grapes, and discusses the potential of biochemical assays and proteomics for early disease management strategies. Continued development of conventional tools and integration with novel approaches is emphasized for improved early disease diagnosis.

Summary: This study aims to investigate the physiological roles of selenium in soybean and its relationship with soybean production through exploring its effect on chlorophyll, antioxidant enzymes, flavonoid biosynthesis, and nodulation. The results show that selenium fertilization can increase the concentration of chlorophyll and carotenoids, boost antioxidant enzyme activity, and increase total sugar content in soybean leaves. Additionally, it enhances ureide concentration and nitrate reductase activity, leading to improved bioavailability of amino acids and proteins in the leaves, promoting plant growth and root dry weight. It also increases the number of nodules and synthesis of rutin and genistein in the roots, facilitating nitrogen fixation. This study provides valuable insights into the role of selenium in soybean physiology, which can be beneficial in improving crop tolerance to environmental stress.

Summary: This study investigated the effects of metal accumulation in Sparus aurata and Chelon labrosus in the Izmir Bay using biomarkers. The results showed higher levels of metals and biomarkers in the liver and gill tissues compared to muscle tissues. Biochemical biomarkers were found to be significant predictors of metal bio-accumulation, and histological changes were observed in the liver and gills.
