Summary: Pontederia cordata has been shown to be tolerant to Cd exposure and can maintain favorable photosynthetic processes and antioxidant activity under short-term Cd exposure. However, prolonged exposure to Cd can lead to membrane peroxidation and decreased photosynthetic pigment content. The phenyl-propane pathway in plant leaves plays a crucial role in defense against Cd stress.

Summary: In this study, the tolerance mechanisms of Monochoria korsakowii, a wetland plant, to heavy metal exposure were investigated. The results showed that under Cd2+ stress, the plant decreased photosynthetic parameters and increased antioxidant enzyme activities. Cd2+ was mainly accumulated in the plant roots, suggesting its potential application in phytoremediation of low-cadmium-polluted water.

Summary: When applied to tomato plants, CdSO4 and ZnSO4 were more easily transported from soil to roots and shoots compared to their nano counterparts CdS QD and ZnS QD. CdSO4 had a greater negative impact on growth and antioxidant properties, while ZnSO4 had an overall positive effect. The mechanisms underlying the responses of CdS QD and ZnS QD were different, suggesting that their nano forms could be a better alternative for crop application.

Summary: Magnesium is an essential nutrient for plant growth and development. This study reveals the effects of magnesium deficiency on citrus plants, including decreased biomass and changes in magnesium concentration and distribution in different organs. Magnesium exists mainly in inorganic and water-soluble forms, and its mobility is related to subcellular distribution and chemical forms. Magnesium deficiency improves magnesium transport from parent to branch organs.

Summary: This study compared the nitrogen removal performances of Acorus calamus, Pontederia cordata, and Alisma plantagoaquatica in farmland wastewater. Pontederia cordata exhibited the highest rate of nitrogen removal and the strongest nitrification-denitrification process in its microbiota. Alisma plantagoaquatica showed the highest nitrogen adsorption capacity. These findings provide insights into the nitrogen removal mechanisms of different plants.

Summary: The research found that Macleaya cordata has a high tolerance to low concentrations of manganese stress and manganese can promote the growth and metabolic activity of Macleaya cordata. However, high concentrations of manganese cause significant damage to the physiology and ultrastructure of Macleaya cordata. The leaves of Macleaya cordata have the highest absorption capacity for manganese, followed by roots and stems. These findings indicate the potential of Macleaya cordata in remediating manganese-contaminated soil.

Summary: The microorganisms and allelochemicals in Pontederia cordata planting water may have a synergistic inhibitory effect on algae. A study investigated the growth and feeding characteristics of Poterioochromonas malhamensis, an algae-inhibiting organism. The growth and feeding of P. malhamensis were influenced by environmental factors and the state of its prey.

Summary: The study found that wetland plants such as P. cordata were more effective at reducing azoxystrobin, while S. latifolia showed greater reduction in imidacloprid levels. Additionally, a list of plant species suitable for phytoremediation of common pesticides in the southeastern United States and similar areas was initiated in this study.

Summary: Large areas of arable lands in China have been contaminated by heavy metals, with cadmium (Cd) contamination being the most prevalent. This study investigated Cd pollution in farmland soils and vegetables in Qujing city, China, aiming to provide guidance for agricultural production in Cd-contaminated farmland. The results showed that the soil Cd concentration was significantly higher than the environmental quality standard, and the Cd concentration in investigated vegetables exceeded the food safety standard. Different vegetables had significant differences in Cd uptake and accumulation. Leafy vegetables had the highest Cd bioaccumulation and transfer factors, while alliums had the lowest. The chemical fractions of Cd in crop roots played a significant role in root-to-shoot Cd transport and Cd accumulation.

Summary: This study identified the protein ZmNRAMP2, which plays a crucial role in root-to-shoot manganese translocation in maize plants. Mutants lacking the ZmNRAMP2 gene showed reduced manganese translocation and inhibited plant growth under manganese deficiency. In contrast, transgenic maize overexpressing ZmNRAMP2 exhibited enhanced manganese translocation and improved tolerance to manganese deficiency. This research provides a promising transgenic approach for developing crop cultivars with increased tolerance to low manganese conditions.
