Summary: Phosphorous (P) is an important macronutrient for plant growth. Phosphate-solubilizing bacteria (PSB) can improve P availability in soil. The co-application of PSB with organic amendments, such as poultry manure, proved to be more beneficial for improving plant growth and yield.

Summary: This study investigated the desorption and solubilization mechanisms of legacy phosphorus in agricultural soils. The results showed that sulfate has a stronger competition for phosphorus desorption, and agricultural soils in the coastal areas are threatened by sea level rise and inundation.

Summary: The pig and poultry industries continue to grow globally, with the EU having the highest relative meat production. The N/P ratio and background soil P levels determine if manure will lead to soil P surpluses. Effective manure management is crucial for the sustainability of these industries.

Summary: The study investigated the use of phosphate solubilizing bacteria (PSB) and poultry manure (PM) for enhancing soil fertility and wheat production. It was found that the addition of nematodes significantly increased the availability of phosphorus and alkaline phosphatase activity. Furthermore, the combination of PM and biological drivers had a greater impact on the dry biomass and phosphorus concentration of plants compared to the control treatment.

Summary: Continuous manure application based on crop nitrogen requirements could lead to nutrient losses, while phosphorus-based application could result in immobilization and fixation of P in soil. Perennial cropping systems have environmental benefits such as reduced nitrate leaching, but converting to an annual system may cause loss of these benefits.

Summary: Continuous manure application based on crop nitrogen requirements can lead to significant nutrient losses in croplands. Phosphorus-based manure application is an alternative, but it may cause microbial immobilization and fixation of phosphorus in soil. This study evaluated the agronomic and environmental benefits and tradeoffs between nitrogen- and phosphorus-based liquid and solid swine manure applications in different cropping systems, and found that some environmental benefits are lost when switching from perennial to annual cropping systems.

Summary: Research on the novel root-specific phytase PvPHY1 from As-hyperaccumulator Pteris vittata showed that it can efficiently utilize organic phosphorus in soil, enhancing plant growth and P accumulation. PvPHY1 facilitates P uptake from soils and phytate hydrolysis in plants, thus promoting tobacco growth.

Summary: EFSA conducted a scientific assessment on the safety and efficacy of 6-phytase produced by a genetically modified strain of Komagataella phaffii for various types of birds. The additive was found to be safe and effective for use in feed, with the exception of respiratory sensitization. The recommended level of use was increased to 1,500 FTU/kg complete feed.

Summary: This study investigated the effects of organic fertilizers on corn growth and soil available phosphorus. The results showed that most of the phosphorus species were inorganic, with calcium-phosphorus and magnesium-phosphorus forms dominant in soybean straw compost and poultry litter compost, and phosphorus mostly associated with aluminum in biosolid pellets. Although chemical fertilizers had the greatest impact on corn height initially, after 42 days, the height was similar for organic fertilizers and chemical treatment. However, the slow initial response of organic fertilizers resulted in lower grain yield compared to chemical fertilizer. Therefore, organic fertilizers have promising potential as phosphorus sources for grain crop production, but further studies are needed to ensure optimum phosphorus supply during the initial growth stage.

Summary: Soil bacteria employ various strategies to overcome the limitation of inorganic phosphorus in soils by secreting extracellular enzymes to degrade organic phosphorus and utilizing specific transporters and intracellular metabolic pathways for phosphorus recycling. The activities of phosphatases are influenced by soil environmental conditions. Regulatory mechanisms play a crucial role in the production of phosphatases, expression of transporters, and metabolic changes in response to phosphorus availability.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: This study cloned the full-length cDNA sequence of TaSPX3 gene in wheat and found that TaSPX3 responds to low phosphorus stress in multiple wheat genotypes. Overexpressing TaSPX3 can alleviate phosphorus deficiency symptoms and promote plant growth in Arabidopsis. The study also revealed the interaction of TaSPX3 with other genes related to the phosphorus starvation signaling pathway.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.

Summary: This study identified a cell number regulator gene called SlCNR8 in willow, which enhances resistance to trace metals in transgenic poplar seedlings. SlCNR8 reduces Cd uptake and accumulation, and can be used as a candidate gene for genetic improvement of phytostabilisation of trace metals.
