Summary: Microbial treatment in sustainable agriculture, specifically involving phosphate-solubilizing bacteria (PSB), has been studied for its growth-promoting effects on plants. The results of this study showed significant increases in root and shoot length, as well as underground and aboveground biomass, with selected PSB strains. Metabolite profiling revealed enhanced levels of key plant growth-related molecules, providing insights into the metabolic mechanisms underlying plant growth promotion by PSB. These findings offer a theoretical basis for the application of PSB in sustainable agriculture practices.

Summary: This study isolated phosphate-solubilizing bacteria from the rhizosphere of quinoa and found that some strains demonstrated tolerance to heavy metals and induced biofilm formation. Inoculation of quinoa seeds with certain bacterial strains showed improved germination rate and seedling growth, suggesting their potential use as inoculants for salty and heavy metal or zinc contaminated soils.

Summary: The study identified phosphate-solubilizing bacteria in karst rocky desertification regions, with Acinetobacter sp. Ac-14 showing sustained and stable phosphate-solubilizing ability. Metabolomics analysis revealed the production of organic acids like gluconic acid by Ac-14, which conferred phosphate solubilization ability to other bacteria. This research indicates that Ac-14 has the potential to enhance phosphorus availability in KRD regions and promote plant growth.

Summary: The study demonstrated that the combination of Pb-resistant phosphate-solubilizing strain of Pseudomonas sp. LA with native plants ryegrass and sonchus could effectively reduce bioavailable Pb in phosphate mining wasteland soil. This bioremediation strategy showed significant potential in enhancing plant growth and mineral uptake, while reducing Pb contamination in the soil.

Summary: Phosphorus (P) is an essential element for plant growth, but its availability in soils is limited. Phosphate-solubilizing microorganisms (PSMs) can convert inorganic P into soluble form and promote plant growth. In this study, a strain called Rhodosporidium paludigenum JYC100 showed good performance in solubilizing calcium phosphate and promoting plant growth. The study highlights the potential use of yeasts as alternatives to chemical phosphate fertilizers, which could improve yields in sustainable agriculture.

Summary: Heavy metal contamination in soils reduces agricultural yield and negatively impacts ecosystem health. The use of green technology, such as metal-tolerant plants and plant growth-promoting bacteria (PGPB), has helped remediate polluted soils. However, global climate change exacerbates the negative effects of climatic stressors on plant growth and metal accumulation. Understanding how PGPB improve environmental stress and metal toxicity while inducing plant tolerance is crucial.

Summary: In this study, endophytic bacterial isolates from roots and shoots of two distantly related rice accessions were characterized phenotypically and genotypically. Five of the most promising plant growth-promoting bacteria were selected to test their abilities to enhance growth of the four rice accessions. Plant growth enhancement was both bacterial isolate specific and plant genotype specific. The positive interactions between plant and bacteria were not easily predictable, indicating a complex relationship between plants and their microbial partners.

Summary: Arsenic, a toxic metalloid, poses a serious threat to food safety and security as it accumulates in food grains due to contaminated agricultural land. Exploration of arsenic-resistant PGPR for crop production is an environment-friendly approach, but its real-time performance depends on various factors. A detailed analysis of mechanisms and constraints is necessary to fully utilize the potential of available arsenic-resistant PGPR germplasm.
