Summary: Plant growth promoting microbes (PGPMs) play crucial roles in various ecosystems, but their potential application in plant micropropagation needs further research. Harnessing the benefits of PGPMs could reduce production costs during micropropagation and enhance the efficiency of plant tissue culture techniques. Further research is needed to explore the full potential of PGPMs in enhancing plant growth and productivity.

Summary: Marginal land refers to land that has little to no utility for agriculture or industry, commonly found on the edge of deserts or arid regions. Plants and microorganisms are used to enhance the soil quality of marginal land, offering a low-cost solution for soil fertility restoration. Plant growth-promoting bacteria play a crucial role in promoting plant development and soil bioremediation. By using economically significant plants and plant growth-promoting bacteria, the soil fertility of marginal land can be improved, leading to the reclamation of general agriculture and restoration of native vegetation.

Summary: This study explored the effects of plant growth-promoting microbe consortia on plant growth promotion and disease prevention. Three new strains were identified and found to have potential for forming consortia with a nitrogen-fixing bacterium. The consortia showed enhanced abilities in promoting plant growth and preventing diseases compared to individual strains.

Summary: This study investigated the combined effect of different light quality and the application of plant-growth-promoting microbes (PGPM) on spinach photosynthetic performance. The results showed that red-blue light increased net photosynthesis compared to white light, but the application of PGPM altered the effect of light quality on photosynthesis. Therefore, the influence of PGPM should be considered when using artificial lighting for controlled environment plant growth.

Summary: This study investigated the plant growth promotion, hydrocarbon degradation, and heavy metal resistance of the Pseudomonas qingdaonensis ZCR6 strain isolated from co-contaminated soil. The in vitro bioassays confirmed its ability to produce indole acetic acid (IAA), siderophores, and ammonia, as well as its capacity for solubilizing phosphate and cellulase activity. The strain also exhibited high activity of 1-aminocyclopropane-1-carboxylic acid deaminase and degradation of petroleum hydrocarbons. Genome analysis revealed the presence of genes associated with various important functions such as nitrogen fixation, phosphate solubilization, heavy metal resistance, and organic compound degradation. The results suggest that ZCR6 has potential for phytoremediation of co-contaminated soils.

Summary: In this study, a new heavy metal tolerant PGPR, Sphingomonas sp. PbM2, was isolated from maize rhizosphere. The siderophore production and 1-aminocyclopropane-1-carboxylic acid deaminase activity of PbM2 were superior to Novosphingobium sp. CuT1, while the indole-3-acetic acid productivity of PbM2 was inferior. PGPR inoculation enhanced Cu bioavailability and bioconcentration factor in HM-contaminated soil planted with maize. Soil PGP activity was significantly enhanced by PGPR inoculation, but plant growth improvement was not statistically associated. The dynamics change in bacterial communities during rhizoremediation was similar regardless of PGPR inoculation, and both inoculated PGPR and indigenous rhizobacteria contributed to Cu bioavailability and soil PGP activity.

Summary: Due to natural and human activities, heavy metal toxicity in soil is a significant threat to the environment and agriculture. Plant growth-promoting rhizobacteria (PGPR)-assisted bioremediation provides a promising and sustainable method for removing heavy metals from contaminated environments. PGPRs use various approaches such as efflux systems, siderophores and chelation, biotransformation, biosorption, bioaccumulation, precipitation, ACC deaminase activity, biodegradation, and biomineralization to clean up heavy metal-contaminated soil. They enhance plant tolerance to metal stress, improve nutrient availability, alter heavy metal pathways, and produce chemical compounds for bioremediation. Genetically modified PGPR strains can further enhance bioremediation efficiency. Overall, PGPRs play a crucial role in promoting sustainable agricultural soil systems through heavy metal bioremediation.
