Summary: Abiotic environmental stress can affect plant metabolism, leading to changes in secondary metabolites. However, the response of these compounds to climate change is not well understood. As the effects of climate change continue to increase, understanding the regulation of secondary metabolism becomes more important. Research is ongoing to investigate the effects of climate change components on secondary metabolites, such as phenolics, terpenes, and alkaloids, and their interactions. Understanding the role of secondary metabolites in plant adaptation to climate change is crucial.

Summary: M. bealei is a traditional Chinese medicine with high alkaloid content used to treat various diseases. Research suggests that UV-B radiation can increase alkaloid and flavonoid contents in M. bealei leaves. The study indicates that UV-B radiation activates oxidative stress response, MAPK signal transduction pathway, and photosynthetic energy metabolism pathway in M. bealei leaves, potentially leading to the accumulation of secondary metabolites.

Summary: Modern agriculture has negative environmental consequences, and scientists are searching for environmentally friendly alternatives to synthetic insecticides. This study examined the effects of four plant secondary metabolites, known as volatile organic compounds (VOCs), on the reproductive processes and larval hatchability of Tenebrio molitor beetles. The VOCs had varying effects on ovarian development, vitellogenin expression, patency index, egg laying, and larval hatchability. Additionally, the compounds showed a repellent effect and reduced insect survivability. Overall, VOCs have potential as bioactive compounds in plant protection.

Summary: Apoptosis is a synchronized cell collapse involving protein degradation and DNA fragmentation, essential for the life cycle of multicellular organisms. It also plays a significant role in cancer development and can be influenced by drugs. Plant secondary metabolites, such as alkaloids and terpenes, have been shown to induce apoptosis by regulating pro-apoptotic and antiapoptotic factors. This article explores the apoptotic triggering mechanisms of some important secondary metabolites.

Summary: There is a growing interest in using beneficial microorganisms as alternatives to chemical or plant-derived molecules for producing therapeutic agents. Bacterial endophytes, which are plant-associated microorganisms, can synthesize a wide range of secondary metabolites with unique chemical structures that have anti-microbial, antiviral, anti-cancer, and anti-inflammatory properties. The production of these bioactive compounds can also benefit the host plant.

Summary: Secondary metabolites are important specialized molecules with proven health-promoting effects on humans. Exogenous jasmonates (JAs) have been recognized for their ability to trigger plant growth and development and can also effectively elicit the synthesis of secondary metabolites. However, large-scale production of these metabolites is limited, but advancements in plant cell culture technology and synthetic biology offer potential avenues for overcoming this limitation.

Summary: Research has found that consuming Brassica vegetables can lead to the formation of DNA adducts in animal models. These adducts can be attributed to specific phytochemicals. Steaming the vegetables may result in higher levels of adducts in the large intestine due to inactivation of the enzyme responsible for activating the phytochemicals.

Summary: The antioxidant activity of bioactive compounds in fruit and vegetables is influenced by factors such as interaction with other molecules, temperature, and the minerals present. Synergistic effects were observed when a 2:1 ratio of ascorbic acid and 5-caffeoylquinic acid was used in the presence of iron, while an antagonistic effect was seen with a 1:2 ratio. Additionally, the pro-oxidant iron positively influenced the antioxidant activity when combined with the antioxidants, showing complex interactions between these compounds and iron.

Summary: The impact of rising CO2 concentrations on glucosinolates and their hydrolysis is still unclear. Research on two Arabidopsis thaliana accessions with different glucosinolate hydrolysis behavior showed that CO2 treatment increased primary production indicators and changed the formation of glucosinolate hydrolysis products. This suggests a potential new pathway for using excess CO2 as a supplement greenhouse gas to produce high-quality food.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
