Summary: This study evaluated the growth-promoting characteristics of three bacterial strains in wheat plants under salinity stress. The results showed that these rhizobacteria positively influenced the physiology, biochemistry, and antioxidant enzymatic activities of the plants, mitigating the adverse effects of salinity stress. Additionally, inoculation of these bacteria increased the expression of stress tolerance genes and can potentially improve the plant's ability to tolerate salinity stress.

Summary: In this article, the authors discuss the potential of monitoring stress volatile release as a non-invasive way to assess the improvement of plant stress resistance conferred by plant growth-promoting bacteria (PGPB). They highlight the mechanisms by which PGPB can enhance plant stress tolerance and induce acclimation responses, and show that PGPB harboring 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase enzyme can reduce stress responses and increase resistance to multiple stresses.

Summary: Global climate change leads to frequent occurrences and/or long durations of abiotic stress, affecting plant growth. Plants modulate ethylene to tolerate stress, but excessive stress can cause ethylene levels to surpass thresholds, leading to reduced growth and productivity. Utilizing ACC deaminase-producing PGPB or developing transgenic plants may be potential solutions to mitigate stress-induced ethylene effects and promote agricultural sustainability.

Summary: The ACC deaminase-producing bacterial strain Achromobacter sp. A1 was found to significantly enhance Cd immobilization in solution, increase maize chlorophyll content, reduce ethylene production, and decrease Cd uptake in maize plants. Furthermore, strain A1 also impacted soil Cd content, enzyme activity, and the expression of Cd transporter genes in maize plants. This suggests that strain A1 has great potential as a novel and environmentally friendly inoculant for mitigating Cd contamination in maize plants.

Summary: Overexpression of the acdS gene in Petunia hybrida significantly reduced ethylene production under stress conditions, leading to greater stress tolerance in the transgenic plants. The improved stress tolerance was associated with better plant growth and physiological performance in the transgenics compared to the wild type plants. These results suggest that overexpression of acdS in ornamental plants can help overcome the detrimental effects of ethylene on plant growth under different abiotic stresses and benefit the floricultural industry.

Summary: This study investigated the plant growth-promoting potential of endophytic bacteria in vegetable crops using the culture-dependent technique. The isolated endophytic bacteria belonged to 15 genera and 39 different species. Bacillus, Enterobacter, Pantoea, and Pseudomonas were the dominant genera and showed high phosphate solubilization and siderophore production potential. The study provides basic knowledge about the cultivable endophytic bacterial community of vegetables and reveals diverse endophytic bacteria that could be useful in improving crop productivity.

Summary: This article presents a brief summary of the biosynthesis of 1-aminocyclopropane-1-carboxylate (ACC) and ethylene in plants, and the roles of ACC and ethylene as signaling molecules. It also discusses how the bacterial enzyme ACC deaminase cleaves plant-produced ACC and prevents ethylene or ACC modulation of plant gene expression. Additionally, it explores the involvement of D-amino acids in stimulating ethylene production in plants, and suggests a possible link between ACC deaminase and the enzyme D-cysteine desulfhydrase.

Summary: In this study, researchers focused on characterizing the plant growth promotion and extracellular hydrolase production traits of rhizobacteria, and their impact on Jerusalem artichoke growth. They found that certain strains of rhizobacteria were capable of promoting plant growth and producing hydrolase enzymes, which significantly improved the growth of Jerusalem artichoke. The researchers recommend the use of these rhizobacteria strains as a biofertilizer to improve soil quality and crop productivity.

Summary: This study investigated the seasonal variation in the bacterial community associated with desert truffle plants and found that summer was the period with the lowest microbial diversity and PGPR functions, while spring was the most active period. The findings are important for further understanding the potential role of desert truffle plants in symbiosis with bacteria and for possible management strategies.

Summary: This study demonstrated the alginate lyase AlyP1400 purified from a marine Pseudoalteromonas bacterium had anti-biofilm activity against Pseudomonas aeruginosa biofilms, which, when combined with antibiotics, reduced biofilm biomass and enhanced the bactericidal activity of antibiotics. The findings suggest the potential value of combinational use of alginate lyase and antibiotics for treating CF lung infections or other P. aeruginosa biofilm-related infections.

Summary: Infectious diseases are a major cause of death worldwide, and the development of antimicrobials has been a significant advancement in medicine. However, the widespread antimicrobial resistance poses a threat to our ability to treat infections effectively. This review focuses on the non-canonical intracellular life cycle of two antimicrobial-resistant bacterial pathogens, Pseudomonas aeruginosa and Staphylococcus aureus, and explores the implications of this unique intracellular niche in contributing to resistance. Additionally, the potential of boosting host immunity as a combination therapy and the importance of surveillance and vaccines in mitigating the impacts of antimicrobial resistance are discussed.
