Summary: Understanding the effects of plant growth-promoting rhizobacteria (PGPR) on Moso bamboo growth, soil nutrient, and microbial community is important for improving Moso bamboo growth. This study established an experiment to quantify the effects of PGPR inoculation on Moso bamboo growth. The results showed that PGPR inoculations significantly increased Moso bamboo biomass, improved soil nutrient content and enzyme activity, increased soil microbial diversity, and stabilized the microbial community. The functional genes related to phosphorus solubilization played a substantial role in activating soil phosphorus. Overall, the applications of PGPR inoculations effectively improved microbial community stability and promoted Moso bamboo growth.

Summary: Inoculating plant growth-promoting rhizobacteria (PGPR) in cannabis plants can enhance yield attributes and chemical profiles. When inoculated with Bacillus sp., Mucilaginibacter sp., and Pseudomonas sp. at the vegetative stage, cannabis showed increased flower dry weight, total CBD, and THC. Inoculation with Mucilaginibacter sp. and Pseudomonas sp. at the flowering stage led to increased total terpene accumulation.

Summary: This study evaluated the effects of three plant growth-promoting rhizobacteria (PGPR) strains on maize plant growth, root parameters, soil nutrients, enzyme activities, and microbial diversity in rhizosphere soil. The results showed that the PGPR strains promoted growth by producing indole-3-acetic acid (IAA) and siderophores. Inoculation with the PGPR strains significantly increased maize seedling height and root length, as well as soil total nitrogen, phosphorus, and potassium. High-throughput sequencing revealed the dominant bacterial phyla in the soil, and the correlation heat map identified the main environmental parameters influencing microbial communities. This study provides valuable data for improving the soil micro-ecological environment and promoting the growth of maize seedlings using PGPR strains.

Summary: Food is a basic human right, but global food security is threatened by crop production. A novel plant growth regulator (PGR) called guvermectin (GV) has been discovered, which can promote root and coleoptile growth, tillering, and early maturing in rice. GV is similar to cytokinin (CK) but functions differently. GV also shows different growth-promoting traits compared to auxin, gibberellin (GA), and brassinosteroid (BR) in Arabidopsis and rice.

Summary: Spent mushroom substrate (SMS) is a serious environmental problem due to its huge output and lack of effective utilization methods. This study investigated the application of composted SMS (CSMS), SMS derived biochar (SBC), combined plant growth-promoting rhizobacteria (PGPR) and SBC immobilized PGPR (BCP) in lettuce seedling. The results showed that the addition of SBC and BCP significantly improved the nutrient content and agronomic properties of lettuce, and enriched the microbial community. Co-occurrence network analysis revealed that BCP greatly increased the network complexity of rhizospheric microorganisms. Overall, this study demonstrated the potential of BCP to improve lettuce agronomic properties and enhance the rhizospheric microbial community.

Summary: The study found that different PGPR strains have significant effects on nitrogen content, rhizobacterial community composition, and the conversion of organic nitrogen to inorganic nitrogen in oilseed rape plants. Initial colonization by PGPR has a lasting impact on rhizobacterial community composition, and network analysis shows that PGPR have species-dependent effects on niche competition in the rhizosphere.

Summary: New technologies are being sought to enhance soil biodiversity and increase crop production while reducing the use of scarce resources to mitigate threats posed by climate change, population growth, and desertification. Challenges still remain in facilitating the delivery of plant-growth-promoting bacteria in the soil, including survival, precise delivery, competition with indigenous soil microorganisms, and soil structure.

Summary: Soil salinity, caused by the changing climate, has become a serious problem worldwide, resulting in damaged soil quality, reduced agricultural production, and decreasing land areas, which has a negative impact on the national economy. Halo-tolerant plant growth-promoting rhizo-microbiomes (PGPRs) are evaluated as excellent agents in controlling biotic-abiotic stresses and promoting crop productivity in salinity-affected agriculture. PGPR-assisted modern agriculture practices have emerged as a green strategy to ensure sustainable farming and mitigate salinity-related stresses. The regulation of PGPR-induced signaling pathways and the application of gene editing tools like CRISPR can contribute to improved plant resistance and adaptability under climate change conditions. The utilization of omics technologies can also enhance crop yields in a sustainable manner, ultimately leading to improved vitality. However, the challenges of crop specificity, acceptance by farmers, and legal regulations need to be addressed for product commercialization in response to climate change.

Summary: This study investigated the soil factors influencing the development of biological denitrification inhibition (BDI) and found that initial soil moisture, ammonium concentration, and the initial abundance of certain microbial genes play significant roles in BDI development. Additionally, the research highlighted the relevance of biotic factors in explaining BDI and proposed the use of procyanidin concentration from plant belowground system as a new proxy for measuring BDI intensity.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
