Summary: The proportion of potential CYN-producers was significantly higher in P-deficient and CYN-present reservoirs in tropical regions. Laboratory experiments showed that CYN upon P deprivation stimulates algal cells to secrete more alkaline phosphatase. Transcriptomics revealed that CYN induced nitrogen allocation and protein export system in Scenedesmus bijugatus under P-deficient condition, enhancing its ALP secretion.

Summary: This study examined the interaction between nitrogen fixation and nitrogen-rich toxin synthesis in the cyanobacterium Aphanizomenon. The results showed that the biomass accumulation in low nitrogen-phosphorus cultures of Aphanizomenon was not affected, unlike other diazotrophic cyanobacteria. However, the production of cylindrospermopsin, a toxin, was lower in nitrogen-fixing populations compared to non-nitrogen-fixing populations. The findings suggest that different strategies in nitrogen fixation may determine bloom magnitude and toxin production patterns in nature.

Summary: The study evaluated the uptake and clearance of Cylindrospermopsin (CYN) in juvenile tilapia, finding higher levels of CYN in the viscera compared to muscle tissue. The toxin remained in the tissues even after 10 days without contaminated food, suggesting the potential for CYN transfer through the food web and the importance of continuous monitoring in organisms used for consumption by humans and animals.

Summary: Nutrient storage is a critical strategy for algae to adapt to changing nutrient supply. This study found that cyanophycin storage supports persistent dominance and blooms of cyanobacteria in tropical waters, particularly during nitrogen-deficient seasons.

Summary: Modified TiO2/Ag3PO4 (T-P25/A) with oxygen vacancies was synthesized through tea polyphenol reduction and chemical deposition methods, effectively inhibiting the growth of harmful algae Cylindrospermopsis raciborskii under visible light. The creation of oxygen vacancies improved the photocatalytic performance of T-P25/A, leading to a 91.75% inactivation rate to Cylindrospermopsis raciborskii after 5 hours of visible light irradiation. The algal inactivation mechanism by T-P25/A was demonstrated through changes in morphological characteristics, cellular content degradation, oxidative species accumulation, and enzyme activity.

Summary: Cylindrospermopsis raciborskii is an invasive species that poses a serious threat to drinking water sources and human health. Bacillus cereus strain L7 was found to have efficient algicidal activity against C. raciborskii FACHB-1503, with the highest activity observed during the decline phase of L7 culture. The coculture system showed optimal conditions at 30 degrees C, pH = 8, and a light-dark cycle.

Summary: A long-term experiment was conducted to study the effects of different chemical forms and rates of nitrogen addition on the composition of soil microbes and the abundance of phosphorus functional genes. It was found that ammonia form-N increased the abundance of P-solubilizing bacteria, while continuous N deposition decreased soil pH and inhibited the viability and activity of bacterial communities. Furthermore, ammonium-N enhanced the relative abundance of most organic P mineralization genes, while nitrate-N showed a decreasing trend.

Summary: The regulation of metabolic pathways and the influence on activity of anammox bacteria under different concentrations of inorganic carbon (IC) were investigated in this study. The results showed that changes in metabolic pathways under IC stress affected the characteristics of anammox. Lower IC concentrations significantly decreased anammox activity through the regulation mediated by guanosine tetraphosphate (ppGpp), while higher IC concentrations enhanced electron transport capacity and growth potential of anammox bacteria.

Summary: Commercial laying hens produce one egg every 24 hours, but as they age, imbalances in calcium and phosphorus utilization can lead to osteoporosis and poor eggshell quality. Therefore, a comprehensive understanding of calcium and phosphorus uptake and utilization is crucial to address these welfare and economic challenges.

Summary: This study investigates the morpho-physio-biochemical and proteomic variation of two rice genotypes under P-starvation stress and reveals the role of protein kinases and Pup1 QTL in enhancing P-deficiency tolerance and P use efficiency. The findings highlight the importance of P metabolism-associated proteins and morpho-physio-biochemical modulations in improving PUE in rice.

Summary: Dam construction has a critical impact on river ecosystems, leading to a rapid decline in biodiversity and ecosystem health. However, the effect of dam construction on the assemblage pattern of benthic diatoms is still unclear. This study found that benthic diatom assemblages in the backwater area of the Three Gorges Reservoir showed differences under low water level and high water level conditions, and were influenced by both environmental and spatial factors. Productivity was found to have a higher relative importance to diatom communities in low water level conditions and minimal impact in high water level conditions.
