Summary: The study identified 84 isolates of Fusarium oxysporum causing wilt symptoms in lettuce plants, and they were all confirmed to be race 1 of F. oxysporum f. sp. lactucae. The susceptibility of different lettuce cultivars to this pathogen was also evaluated, with Cencibel and Lugano being highly susceptible and Sandalina and Starfighter being the most resistant. The expression analysis of defense-related genes revealed that resistant cultivars showed higher induction rates and earlier induction levels in response to infection.

Summary: The application of copper nanoparticles through foliar spraying increases the yield and content of bioactive compounds in lettuce without negative effects on yield. The activity of superoxide dismutase and catalase enzymes in lettuce plants is also increased with the application of copper nanoparticles. Therefore, better quality lettuces with higher production of bioactive compounds are produced for the human diet through the application of copper nanoparticles.

Summary: Weed management is crucial for crop protection, but chemical weed control using synthetic herbicides has drawbacks. Metabolomic investigation of allelopathy could offer new alternatives for weed control. This study focused on the metabolomic responses of plants to allelochemicals in Iris seed extracts, identifying 3-hydroxyirisquinone as a major allelochemical. The compound inhibited plant growth and affected metabolic pathways, leading to oxidative stress and growth inhibition. These findings provide valuable information for the development of allelochemical-based herbicides.

Summary: The study found that contamination of lettuce plants with acetaminophen (ACT) can induce oxidative stress and increase stress indicators, while also causing significant changes in the enzymatic activities related to the antioxidative system. Additionally, ACT has a specific impact on the glutathione cycle in contaminated leaves, and induces an antioxidative response in lettuce plants with significant increases in anthocyanin content.

Summary: Selenium (Se) plays a vital role in plant growth and development. It is also an essential nutrient for humans and animals as it is primarily obtained from plant foods. This study investigated the effects of different concentrations of exogenous Se application on the growth, antioxidative capacity, and nutritional quality of purple lettuce at the seedling stage. The results showed that low Se application concentrations promoted lettuce seedling growth, while high concentrations inhibited growth and caused oxidative damage. Additionally, exogenous Se application increased the accumulation of nutrients and anthocyanins in purple lettuce. The findings contribute to understanding the role of Se in lettuce growth and provide insights for producing high-quality, Se-rich, anthocyanin-rich purple lettuce.

Summary: Tipburn is a physiological disorder that causes leaf discolouration in lettuce and other leafy crops, leading to quality issues for the fresh produce industry. The underlying physiological and molecular basis of the disorder, which is linked to calcium deficiency, is poorly understood. However, a study on vacuolar calcium transporters in different lettuce cultivars found that some genes associated with calcium transport exhibited higher expression in resistant cultivars, providing insights into potential breeding strategies for developing resistant varieties.

Summary: This study quantitatively investigates the impact of land use on water quality in the Honghu Lake Basin. Results indicate severe nitrogen and phosphorus pollution in the basin, with significant seasonal variations and spatial distribution differences. Correlation analysis shows that forests and wetlands are negatively correlated with nutrient concentrations, while cultivated lands and residential communities are positively correlated. Redundancy analysis reveals that the best explanation for water quality spatial variation is at a small scale and in the rainy season.

Summary: This study investigated the fluctuating profiles of physicochemical and microbial characterizations along different filling heights of continuously up-flow solid-phase denitrification columns packed with PCL. It was found that both the PCL filling area and non-filling area significantly contributed to treatment performance, with denitrification mainly occurring near the bottom of the filling column. Nitrate showed high removal rates, while nitrite and ammonium displayed weak accumulation in final effluents.

Summary: The study evaluated the eco-friendliness of rice-crayfish co-culture compared to other aquaculture models in terms of antibiotic resistance profiles. Results showed that rice-crayfish co-culture model had significantly lower diversity of ARGs and lower potential risks when compared to other aquaculture models. Environmental factors such as nutrient and antibiotic concentrations played a role in shaping ARG patterns, but the effects of mobile genes and bacterial community were stronger in the proliferation and transmission of ARGs.

Summary: This study systematically surveyed heavy metal contamination in the aquatic environment and organisms of Dianchi Lake. The results showed that heavy metals were highly concentrated in the northern and southern parts of the lake. The different fractions and bioaccumulation effects of heavy metals were observed in sediments and aquatic organisms. Ecological risk assessment revealed the dominant heavy metal contaminants in water and sediments, while human health risk evaluation highlighted the major contribution of a specific heavy metal. The findings contribute to environmental safety and human health in the studied area.

Summary: In this study, wood chips and bark were used as natural solid carbon sources to enhance the denitrification capacity of lakeshore sediment and remove excess nitrate in wastewater treatment plant tailwater. The results showed that wood chips were more effective in enhancing the denitrification ability of lakeshore sediment for a longer period of time. Wood chips also promoted microbial activity and nitrate and nitrite reductase enzyme activities, facilitating denitrification in the sediment.

Summary: The abundance and diversity of antibiotic resistance genes (ARGs) in surface water and groundwater were found to vary inconsistently with seasonal changes. The relationship between ARGs in surface water and groundwater was stronger during the rainy season. Additionally, land use had a greater impact on ARGs in surface water, especially during the dry season. Stochastic mechanisms mediated by mobile gene elements (MGEs) significantly contributed to ARG assemblages, particularly in groundwater.

Summary: In this study, long-term data were used to analyze the succession characteristics and drivers of zooplankton communities in Honghu Lake, China. Results showed significant changes in zooplankton community structure over a period of 62 years, with a decrease in species number and an increase in abundance and biomass. The main driving factors were found to be aquatic environment, land use patterns, and climate factors, with aquatic environment having the highest direct explanation on zooplankton variation.
