Summary: In savanna ecosystems, tree canopy patches have different plant species composition and functional trait assemblages compared to intercanopy spaces due to varying mistletoe infection intensities. Higher mistletoe infection levels enhance species richness and diversity, as well as functional diversity. Canopy patches with high mistletoe infection show significantly greater species richness and diversity of C3, C4, annual, and perennial plants.

Summary: Radiation can be lethal at high doses, but beneficial in controlled doses for medical applications. Plants evolving in radiation conditions have demonstrated the ability to protect organisms against radiation. Studies on plant-based radioprotection have shown promising results and further research is needed to develop effective and safe radioprotectants for clinical use.

Summary: Fresh-cut produce, including different root colors of carrots, have been studied for their response to postharvest UV-C radiation and cold storage. Results showed that purple carrots were not affected by UV-C radiation, while yellow and purple carrots could experience tissue browning after fresh-cut processing. Therefore, UV-C radiation has the potential to increase the functional value of different carrot root colors.

Summary: Tartary buckwheat and common buckwheat are adapted to grow in harsh conditions of high altitudes. The synthesis of UV-B defense metabolites, including flavonoids and rutin, is genetically conditioned and depends on the intensity of ultraviolet radiation. These substances are formed in the leaves and flowers of both buckwheat species, while the concentration of rutin in Tartary buckwheat grain is significantly higher. Flavonoids have protective functions against pests and diseases in plants and also play an important role in human nutrition and the prevention of chronic diseases.

Summary: Human skin acts as a barrier against harmful effects of environmental agents, including UV radiation. Proper preventive measures like sunscreen use can avoid over 90% of skin cancer cases. Plants, constantly exposed to sunlight, synthesize specialized molecules to combat UV damage, making them an important source for UV protection and prevention of skin cancers. This study reviewed the main plant secondary metabolites related to UV protection and their mechanisms, and summarized the research on Mexican plants in terms of UV protection and photoprotective molecules.

Summary: An experimental isolation of clovamide molecule from Vernonia fastigiata was conducted, and its E and Z geometrical isomers were characterized using liquid chromatography-mass spectrometry. The most thermodynamically stable isomer was determined to be the E isomer. Clovamide exhibited stronger (OH)• scavenging ability in non-polar medium compared to (OOH)•, and the preferred mechanism of radical scavenging was hydrogen atom transfer.

Summary: Electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and gravimetric analysis were used to evaluate the ability of Lippia javanica leaf extract to inhibit aluminum corrosion in acidic solution. The extract decreased corrosion current density and double-layer capacitance, and formed a protective adsorption layer on the aluminum surface. The maximum protective efficacy was 91.89% at an optimal concentration of 800 ppm. The extract changed the contact angle and revealed the involvement of various functional groups in the adsorption process. Density functional theory (DFT) analysis showed the preferred binding position of the extract on the aluminum surface.

Summary: South Africa is rich in diverse medicinal plants, with over 35% of the global Helichrysum species. However, there are knowledge gaps regarding the size and diversity of the Helichrysum chemical space. This study aimed to comprehensively characterize the metabolic landscape of Helichrysum splendidum, a less studied medicinal herb. The results revealed a chemically diverse metabolic map, with potential bioactive compounds that showed strong interactions with anti-cancer targets. These findings suggest the potential of H. splendidum-derived compounds as anti-cancer agents.

Summary: In this study, a metabolic profiling approach and classical molecular networking were used to investigate the differences in polyphenol profiles between Viscum combreticola Engl. and Viscum album L. The results showed that the two species had distinct polyphenol profiles, which could serve as chemotaxonomical markers. Additionally, molecular networking was shown to be a powerful tool for visualizing differences in chemical composition. The diverse polyphenol profiles of these species are likely influenced by their unique metabolism, which is influenced by their genetic makeup.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
