Summary: Secondary active substances have been widely used in various industrial fields due to their unique biological activities. Euryale ferox, also known as prickly waterlily, is an important commercial crop with numerous health functions, but information on its secondary metabolites is limited. In this study, 589 secondary active substances were identified in different tissues of E. ferox using UHPLC-MS/MS technique, with polyphenols being the predominant compound. Flavonoids were found to vary the most among the five tissues. The antioxidant evaluation revealed that the seed shell possessed excellent antioxidant properties. The study also demonstrated the remarkable activity of EfPAL4 in the biosynthesis of polyphenols and flavonoids through enzyme activity assays and overexpression in Arabidopsis. These findings provide important insights for the future industrial application of E. ferox.

Summary: AevPAL1 helps to confer CCN resistance by affecting the synthesis of salicylic acid (SA) and downstream secondary metabolites. The silencing of AevPAL1 increased the incidence of CCN infection in roots and decreased the accumulation of SA and phenylalanine (Phe)-derived specialized metabolites. These results suggest that AevPAL1, possibly in coordination with AevTDC1, positively contributes to CCN resistance in Ae. variabilis.

Summary: This study investigated the effects of elevated CO2 concentration (e[CO2]) and exogenous abscisic acid (ABA) on the drought tolerance of cucumber seedlings. The results showed that the combination of e[CO2] and exogenous ABA significantly improved the growth and photosynthetic activity of cucumber seedlings under drought stress. Moreover, it also reduced oxidative damage and increased the accumulation of antioxidant substances in cucumber seedlings. These findings suggest that e[CO2] and exogenous ABA can effectively alleviate drought stress in cucumber seedlings.

Summary: This study found that elevated CO2 levels can impact the growth and chemical composition of sprouts, increasing the accumulation of bioactive compounds and enhancing antioxidant, antibacterial, anti-inflammatory, hypocholesterolemic, and anticancer activities. Sprouting with elevated CO2 exposure presents a promising approach to produce sprouts with improved health-promoting properties for diseases.

Summary: The experiment found that low-temperature stress led to rapid closure of stomata and a 21% decline in net photosynthesis. When elevated CO2 interacted with low-temperature stress, chlorophylls and carotenoids decreased. Under high-temperature stress, basil showed increased stomatal conductance, intercellular CO2 concentration, apparent quantum yield, maximum photosystem II efficiency, and maximum net photosynthesis rate. Increasing the growth temperature from 30/22 degrees C to 38/30 degrees C under elevated CO2 significantly increased the antioxidants content of basil.

Summary: This study evaluated the potential of plant growth-promoting Actinobacteria (PGPB) in improving physiological and molecular parameters of rapeseed plants under ambient and elevated CO2 conditions. The results showed that PGPB treatment combined with elevated CO2 levels resulted in increased photosynthetic pigments, photosynthesis rate, biomass production, and antioxidant capacity, as well as improved nitrogen- and sulfur-containing metabolites. The interaction effects of PGPB and elevated CO2 are expected to enhance plant biomass and adaptability to future climate changes.

Summary: This study investigated the changes in growth, photosynthesis, and phytochemicals of caraway plants at different developmental stages under control and increased CO2 conditions. The results showed that CO2 enrichment promoted photosynthesis and biomass accumulation in both caraway stages, while impacting phytochemical contents differently depending on the developmental stages. Furthermore, the antioxidant and antibacterial activities of caraway plants were enhanced under eCO2 treatment, particularly at the mature stage.

Summary: Increases in atmospheric CO2 can promote plant growth under heavy metals stress conditions, but the mitigating effect of vanadium (V) stress under enhanced CO2 levels has not been well studied. This study investigated the growth and biochemical responses of wheat plants under V and enhanced CO2 conditions, and found that high V levels inhibited plant growth and induced oxidative damage. However, under enhanced CO2, wheat showed reduced V uptake and toxicity, leading to improved growth through increased photosynthesis and enhanced antioxidant production.

Summary: The study showed that using chitosan (CHT) as an elicitor in callus cultures of Lepidium sativum can significantly enhance total phenolics content, PAL activity, antioxidant capacity, and callus fresh weight. Additionally, the treatment with CHT also led to a substantial increase in lepidine accumulation.

Summary: This study investigated the phenotypic variations in response to ammonium nutrition in five oil palm genotypes seedlings. The results showed that ammonium nutrition increased shoot growth in all genotypes and there was a trend towards increased primary root length, amino acids, proteins, and nitrogen uptake. These findings are promising for the sustainable use of ammonium with inhibitors.

Summary: The study found that under combined treatment of elevated CO2 and cadmium, the richness and diversity of arbuscular mycorrhizal fungi (AMF) community decreased, while the activities of superoxide dismutase and peroxidase increased. Cadmium content was negatively correlated with AMF community richness and gene abundance, and certain AMF had significant effects on antioxidant enzyme activities.

Summary: In elevated CO2 conditions, the leaf nitrogen concentration of Fraxinus rhynchophylla seedlings was not reduced by nonstructural carbohydrate accumulation, suggesting a potential link with increased photosynthetic N-use efficiency. Contrary to expectations, leaf NSC decreased under elevated CO2, while stem nitrogen concentrations increased, indicating a complex response of different plant organs to elevated CO2 and nitrogen availability.

Summary: This study aims to investigate the interactive impacts of elevated CO2 (eCO2) and selenium nanoparticles (SeNPs) on wheat plants. The results showed that the application of SeNPs combined with eCO2 can enhance photosynthetic pigment content, Rubisco activity, and stomatal conductance, resulting in improved photosynthesis capacity and dry matter production. The combined treatment also led to increased content of antioxidant enzymes, molecules, and metabolites. Overall, the synergistic effects of eCO2 and SeNPs were more advantageous for plant growth and metabolism compared to individual treatments.
