Summary: The study found that low nitrogen supply significantly affects carbon metabolism, amino acid metabolism, and phenolic biosynthesis metabolism in lettuce, leading to a significant increase in phenolic content. This suggests that low nitrogen treatment may effectively redirect carbon and nitrogen resources to the phenolic biosynthesis pathway, thereby increasing the phenolic accumulation in lettuce.

Summary: This paper investigated the selenium accumulation ability of lettuce and the effects of selenate and selenite on its growth and amino acid content. The results showed that lettuce could effectively convert inorganic selenium into organic selenium, and the addition of selenium improved photosynthesis and growth. The optimal selenium application was found to be 2 mu mol L-1, with some regions able to use 4 mu mol L-1 selenite. However, excessive selenium areas are not recommended for growing selenium-rich foods. Overall, lettuce has strong biofortification potential.

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: This study investigated the changes in phenolic compounds content in lettuce under different LED lighting conditions in a greenhouse. Supplemental 400 nm and 455 + 530 nm LEDs showed the most positive effect on total phenolic compounds. The effect of LED lighting varied depending on the timing and season of cultivation.

Summary: The study found that the phytoavailability of metals in lettuce leaves was most effectively limited by multinutrient fertilizer and a mix of straight fertilizers, with organic fertilizer being the least effective. Higher accumulation was observed for macroelements, while poor bioaccumulation was found for Cr, Mn, Ni, and Zn.

Summary: Pharmacologically active compounds (PACs) are common pollutants in the natural environment and pose potential risks to crop quality. The study found that treatment with ketoprofen adversely affected respiration rate, carbon and nitrogen metabolism, and metabolomics in rice seedling leaves, resulting in a reduction of rice seedling biomass.

Summary: This study evaluated the impact of salinity as a eustressor on the functional quality of red lettuce. The results showed that moderate salt stress increased the phenolic compound concentration and antioxidant activity, while severe salt stress decreased antioxidant activity and biomass production.

Summary: The use of contaminated water for crop irrigation poses a risk to human health due to the potential accumulation of microcystins in edible vegetable tissues. This study found that water samples used for irrigation exceeded the safety limit of microcystins set by the WHO, and the concentration of microcystins in leafy green plants exceeded the guidelines for human consumption. Regular testing for microcystins in irrigation water and vegetables is recommended to prevent the accumulation and transfer of these toxins through the food chain.

Summary: The effects of two types of arbuscular mycorrhizal fungi (AMF) inocula on lettuce and green onion were examined. The AMF inoculation did not significantly affect the yield and root system architecture of the crops. Nitrate accumulation was within the limits set by the European Commission. However, important phytochemical characteristics and antioxidant capacity showed a tendency for reduced values in the AMF-treated lettuce.

Summary: Endophytic entomopathogenic fungi like Beauveria bassiana can improve yield and quality of lettuce by promoting growth and protecting against insect infestations. This study found that B. bassiana was pathogenic to aphids, increased micro-nutrient tissue contents, and enhanced antioxidant activities in plants, highlighting its potential for biofortification of nutritive and medicinal qualities.

Summary: The NO3-:NH4+ ratio significantly affects the growth and quality of hydroponically grown lettuce. Overall, a ratio of 75:25 has been found to be the most conducive for lettuce growth and nutritional quality. Other ratios also have varying effects on different physiological parameters and mineral contents of lettuce.

Summary: In this study, the effects of different combinations of red and blue light on the synthesis and recycling of Ascorbate (AsA) in lettuce were investigated. The results showed that exposure to a 1:1 or 2:1 ratio of red and blue light significantly increased the levels of AsA in lettuce leaves. The activity of key enzymes involved in AsA production and cycling was also enhanced. However, the accumulation of hydrogen peroxide and malondialdehyde was observed following red and blue light treatments. Overall, this study suggests that irradiation with a blue light proportion of over 50% can improve AsA accumulation in lettuce.

Summary: This study found that UVA-blue co-irradiation positively affected the growth and anthocyanin biosynthesis of pak choi, with the enhancement of anthocyanin synthesis reaching a peak at a UVA light strength of 10 mu mol·m(-2)·s(-)(1). In addition, there were variations in the expression patterns of MYB1 and PAP1 genes between different cultivars of pak choi.
