Summary: This study evaluated the potassium dynamic nutrition in eucalyptus in response to soil-K and -water availabilities, finding that eucalyptus clones with sufficient potassium were able to maintain biomass accumulation under severe drought conditions compared to those with low potassium levels. The importance of potassium nutrition in maintaining leaf photochemical processes was highlighted, showing positive correlations between potassium use efficiency and electron transport rate through photosystem II in plants grown in low potassium conditions. Management strategies should focus on enhancing potassium nutrition to optimize water-use efficiencies and photosynthesis.

Summary: This study evaluated the growth performance, biomass, nutrient content, and nutrient use efficiency of ten Eucalyptus clones at three sites in Leizhou Peninsula. The results showed significant genetic variation among the clones in growth parameters, with different organs exhibiting different biomass and nutrient content characteristics. Among the ten clones tested, LH1-9211, TH9224, DH32-13, M1, and DH32-22 consistently showed the best growth and production performance.

Summary: This study found that mixed Eucalyptus forests significantly enhanced soil aggregate stability and phosphorus content, especially the Eucalyptus-Mytilaria laosensis mixed forest. Total soil phosphorus and its fractions decreased with increasing aggregate particle size, while stored phosphorus showed the opposite trend, with aggregates <0.25 mm being the main fraction influencing soil phosphorus accumulation.

Summary: Plants can recycle phosphorus by retrieving it from senescing tissues, reducing the need for phosphorus uptake from soils. Species from low-phosphorus ecosystems possess traits that enhance phosphorus recycling. Root traits and dynamics knowledge lags behind leaves, but root phosphorus concentrations, lifespans, resorption percentages, and biomass allocation are comparable to those of leaves. Relationships among traits influencing phosphorus recycling appear more complex in roots than in leaves.

Summary: Acid soils cover approximately 50% of arable lands, and improving crop productivity in these soils is crucial for food security and agricultural sustainability. The combination of high soil acidity, phosphorus deficiency, and aluminum toxicity severely affects crop growth and yield. Legumes, such as soybeans, have evolved mechanisms to adapt to these stresses, including root architecture modification, exudation, and symbiosis. Breeding legume cultivars with superior nutrient efficiency and aluminum tolerance traits through genetic selection could be a powerful strategy for maintaining or improving yields in challenging soil conditions.

Summary: This study evaluated the salt tolerance of different Eucalyptus clones in saline soil areas. The results showed that the clone I144 exhibited the highest salt tolerance, with stronger antioxidant enzyme activity and osmotic adjustment. On the other hand, the clones VC865 and I224 showed moderate tolerance and sensitivity, respectively.

Summary: Aluminized acidic soil can damage Eucalyptus roots and limit tree growth. The responses of tolerant Eucalyptus clones to aluminum toxicity were investigated, and the results show that different clones have different levels of tolerance. The uptake of pectin and changes in cell wall polysaccharide content and enzyme activity may explain the stronger aluminum resistance in some clones. Maintaining higher nitrogen and potassium levels in roots may be an important mechanism for effectively alleviating aluminum toxicity.

Summary: This study analyzes the nitrogen and phosphorus allocation strategies between leaves and fine roots in terrestrial plants using a global dataset. The results show divergent scaling relationships between N and P in different plant organs, improving our understanding of the effects of environmental changes and life-history strategies on nutrient allocation patterns between these two important plant organs.

Summary: Phosphorus availability has a significant effect on leaf function and Cd tolerance of poplar leaves. Phosphorus deficiency reduces photosynthesis and antioxidant defense, while sufficient phosphorus nutrition enhances plant tolerance to Cd.

Summary: This study investigated the influence of phosphorus (P) on the formation of iron plaque on rice roots and its impact on cadmium (Cd) uptake. The results showed that while P supply enhanced the formation of iron plaque, it reduced the retention capability of Cd. Excessive P fertilizer application can lead to increased accumulation of Cd in rice plants.

Summary: This study conducted neutron activation analysis and gamma spectrometry on the stems, roots, and leaves of vegetables. The results showed that the accumulation of radionuclides and multi-elements in plants depended on the plant type and parts. The activity concentrations of 226Ra and 232Th followed the order: Roots > Stems > Leaves. The highest concentrations of 40K and 210Pb were found in the stems and leaves, respectively. The essential nutrient requirements of plants were ranked as: K > Ca > Mg > Fe > Zn > Mn. Among the non-essential metals, the concentration of Na in vegetable samples was much higher than others. The K/Na ratio in plants varied depending on the plant type and translocation within the plant.

Summary: Black Phosphorus Quantum Dots (BP-QDs) have shown potential biomedical applications but may cause respiratory toxicity when entering the body. This study confirmed the respiratory toxicity of BP-QDs in mice and human bronchial epithelial cells by observing lipid peroxidation and iron overload. The findings suggest that BP-QDs induce ferroptosis by increasing lipid peroxidation and iron accumulation in vitro and in vivo.

Summary: The research found that melatonin can reduce the arsenic content in rice seedlings and promote the generation of functional groups, thereby reducing the deposition of arsenic on the cell wall. Melatonin also helps to scavenge excess H2O2, reduce MDA content, and maintain the normal morphology of root cells by stimulating antioxidant enzyme activities and increasing GSH level, contributing to the redox homeostasis in rice cells.
