Summary: This study investigated the effects of nitrogen addition on the accumulation and gene expression levels of carbon-based secondary metabolites in Cyclocarya paliurus leaves. The results showed that intermediate nitrogen addition led to the highest contents of polyphenols, flavonoids, and triterpenoids in the leaves. However, there was a trade-off between the accumulation of these bioactive substances and leaf biomass production.

Summary: This study investigated the effects of nitrogen (N) addition with different organic nitrogen (ON) to inorganic nitrogen (IN) ratios on the growth and stoichiometric characteristics of Cyclocarya paliurus. The results showed that N addition with different ON:IN ratios led to a decrease in growth rate and biomass accumulation, while leaf phenolic content showed an opposite trend to leaf stoichiometry. These findings indicate that N addition caused stoichiometric imbalance and altered plant growth and accumulation of secondary metabolism substances. Consideration of nutrient limitation type and variation in N deposition components is necessary to predict the future responses of plant functional traits to N deposition.

Summary: Co-inoculation with phyto-stimulatory and nutrient-enhancing bacterial strains on barren land enhanced soil nutrient availability, promoted root system modification, increased photosynthesis rate, nutrient acquisition, and plant growth. Medium fertilizing level with beneficial microbes resulted in the accumulation of flavonoids and polysaccharides, while low fertilizing level with specific bacterial strains facilitated the production of flavonoids and triterpenoids in Cyclocarya paliurus leaves. The biosynthesis of bioactive compounds in the leaves was influenced by internal nutrient balance and root system morphology modified by bacterial inoculation.

Summary: In this study, a novel Mg-modified lignin biochar (MB) was prepared to improve the ability of phosphate-solubilizing bacteria (PSB) to dissolve FePO4. The results showed that the system with MB was more effective in increasing FePO4 dissolution and organic acid production. Characterization results revealed the formation of Fe(III)(2)Fe(II)(P2O7)(2) crystals on the surface of MB, which increased the solubility of Fe-P. This study provides a new method for the development of insoluble phosphate solubilization technology.

Summary: Soil microorganisms play a crucial role in maintaining ecological balance, particularly through their involvement in nutrient cycles. Phosphate-solubilizing bacteria (PSB) are of particular importance in the rhizosphere and can be used as biofertilizers in agriculture. This study identified five species of PSB, including Pseudomonas fluorescens, P. putida, P. taiwanensis, Stenotrophomonas maltophilia, and Pantoea agglomerans, through genetic sequencing. The PSB isolates exhibited varying degrees of phosphate solubilization, with P. fluorescens showing the highest solubilization ability. Additionally, all five PSB species were capable of producing the growth-promoting hormone indole acetic acid (IAA), with P. fluorescens producing the highest quantity.

Summary: Fourteen previously unreported 3,4-seco-dammarane triterpenoids, along with four known derivatives, were isolated from Cyclocarya paliurus leaves. Two of the compounds possess a rare lactone structure and the configurations of multiple pairs of epimers were determined for the first time. Some of the compounds demonstrated potent inhibitory effects on α-glucosidase and COX-2, as well as significant cytotoxicities against human gastric and colon cancer cell lines.

Summary: Phosphate-solubilizing bacteria can relieve phosphorus deficiency without causing pollution. This study investigated the gene expression patterns and organic acid production of a phosphate-solubilizing bacterium under different phosphorus conditions. The results showed that genes related to the citrate cycle pathway were significantly upregulated, leading to increased production of organic acids. This study provides new insights for improving calcareous soils and reducing reliance on chemical phosphate fertilizers.

Summary: The present study aimed to design a biofertilizer using phosphate solubilizing bacteria (PSB) and locally produced fruit waste. The evaluation of the prepared compost revealed that it was safe, beneficial for soil fertility, and could be used as a phosphatic biofertilizer. This study encourages the use of PSB-rich compost to improve and sustain soil fertility.

Summary: Periodic inoculation with phosphate-solubilizing and N-2-fixing bacteria can enhance plant growth and soil nutrients. Repeated inoculations do not increase the benefits from inoculants, and these benefits are not maintained after transplantation. Inoculations impact the succession of resident bacterial communities in bulk soil, primarily influenced by changes in soil pH and nitrate levels.

Summary: Introducing probiotics to soil can stimulate plant metabolite production, but soil-resident microbes may affect the efficiency of probiotics. This study investigated the effects of different fertilization regimes and soil microbes on the accumulation of plant metabolites. The results showed that fertilization regimes and soil microbes play a crucial role in influencing plant metabolite production. Identifying microbial indicators can help understand the effects of probiotics and improve plant productivity.

Summary: Periodic inoculations of soil-beneficial microbes increase their populations but also act as recurring biotic disturbances on the native microbial community. Rare and abundant microorganisms disproportionately shape community diversity and stability. Understanding their dynamic responses and driving factors helps improve our understanding of inoculation effects.
