Summary: Free radicals are crucial in cellular chemical processes, but many synthetic antioxidants are known to be carcinogenic. Natural antioxidants without side effects are being sought, and lichens containing phenolic compounds may be suitable candidates. This study aims to compare the activity of metabolites involved in radical scavenging using micromolar concentration calculations.

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: Specific OsGDPD genes are upregulated in rice leaf blades under elevated CO2 conditions, and they function in the plastid. Excess carbohydrate accumulation under elevated CO2 leads to local phosphorus deficiency, affecting the activity of GDPD and hydrolysis of glycerophosphodiester.

Summary: The importance of studying the effects of CO2 concentration on metabolism increases with the rise of global atmospheric CO2 concentrations. However, the reasons behind how CO2 concentrations affect carbohydrate and phenolic metabolism are still unknown. In this study, a novel phenolomic approach was used to investigate the quantitative and spatial variations of phenols in wolfberry under elevated CO2 conditions. The data obtained from various analytical techniques provided a comprehensive overview of phenolomic quantities and spatial distribution. The findings suggest that phenolics and precursors accumulate and gene expression changes occur under elevated CO2, which may act as strategies to cope with the stress associated with elevated CO2. Pathway analysis revealed changes in metabolite levels and the expression of key genes related to glyoxylate, phenylpropanoid, and flavonoid metabolism. Additionally, mass spectrometry imaging showed specific spatial distribution patterns of different metabolites in the berry. Overall, this study demonstrates the potential of spatially resolved phenolomics and provides insights into the phenolomic response to elevated CO2 atmosphere.

Summary: Due to their widespread occurrence, fungi in the genus Penicillium are commonly found in association with insects. This symbiotic interaction has been investigated to explore their potential for ecofriendly pest control strategies. The assumption is that Penicillium species, known for producing bioactive secondary metabolites, may have entomopathogenic properties. This review paper examines the properties and potential applications of compounds from Penicillium fungi in insect pest management.

Summary: The application of exogenous ATP increased endogenous ATP content in strawberry fruit under elevated CO2, delaying the decrease of energy charge and inhibiting the accumulation of acetaldehyde and ethanol. Additionally, ATP treatment maintained carbohydrate levels and repressed enzymes activities and gene expressions involved in sucrose catabolism and glycolysis. These results suggest that exogenous ATP could be a strategy to optimize elevated CO2 treatment and avoid its adverse effects.

Summary: Drought is a serious threat to rice production caused by climate change. Comparative multi-omics analysis of drought-tolerant and drought-sensitive rice cultivars identified the molecular mechanisms involved in drought tolerance/response. This study characterized the global transcriptome, proteome, and metabolome profiles and integrated them to reveal the role of transporters, translational machinery, aromatic amino acids, soluble sugars, and auxiliary carbohydrate metabolism in drought tolerance.

Summary: Elevated CO2 has been shown to have positive effects on plant growth and metabolic processes, but can also negatively impact crop quality. The effects of elevated CO2 on plants vary under different biotic and abiotic stresses, influencing phytohormone concentrations and secondary metabolite production.

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: The severity of salt stress poses a significant threat to crop growth and food security. Current strategies to reduce stress are not always environmentally friendly or sustainable. In this study, the researchers investigated the use of plant-growth-promoting rhizobacteria (PGPR) as a sustainable stress reduction strategy. They found that the application of Pseudomonas fluorescens individually was effective in reducing stress and improving plant growth and photosynthesis, but the greatest alleviation was observed with the combined application of Pseudomonas fluorescens and Azotobacter chroococcum. The combined application resulted in decreased oxidative stress, increased osmolyte content, and enhanced antioxidative enzyme activity, leading to improved cell viability and reduced damages to the leaves. Based on these results, supplementing plants with PGPR in combination can mitigate the negative impacts of salt stress and increase plant yield.
