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: Saline soils pose a significant challenge to agriculture, and there is an increasing need to find effective solutions to improve plant salt tolerance. This review article explores the potential of using plant growth-promoting bacteria, both endosymbiotic and exosymbiotic, to enhance plant growth and alleviate salt stress in saline soils. The mechanisms and applications of these bacteria are discussed to provide a theoretical basis for their future use in agricultural systems.

Summary: This study investigated the survival mechanisms of plant growth-promoting rhizobacteria (PGPR) under salt stress conditions. Different strains employed different strategies to cope with salt stress, with the GB03 strain exhibiting enhanced swarming mobility and the WCS417r and SJ04 strains showing reduced swimming motility. The WCS417r strain showed increased biofilm formation and autoaggregation capacity under high salt concentrations. Inoculation with these strains alleviated the detrimental effects of salinity on plant growth.

Summary: This study conducted a detailed analysis of the microevolution of a parental Mycobacterium tuberculosis strain into clonal variants within a patient with poor treatment compliance in Argentina. The microevolution was mainly driven by drug selective pressure, with rare short-term mutations fixed together with resistance-conferring mutations during therapy. The report highlights the importance of whole-genome sequencing analysis in the clinic for evaluating pre-XDR and MDR resistance profiles in patients with incomplete and/or intermittent treatment.

Summary: This review discusses the challenges posed by antibiotic-resistant bacterial strains and the declining private investment in developing new antimicrobials. It highlights the importance of utilizing multi-omics data, structural/functional analysis, and systems biology to prioritize candidate proteins for drug discovery, as well as the use of virtual screening to explore potential inhibitors and guide the development of new drug lead compounds. The advent of omics and the application of bioinformatics strategies in the big-data era have improved target selection and lead compound identification in a cost-effective and shortened timeline.

Summary: Carbapenem-resistant Klebsiella pneumoniae (CR-KP) is an emerging threat to public health, and the development of novel antimicrobials is urgently needed. This study used genome-wide interrogation and metabolic data integration to identify potential targets for drug development. Pathways involved in lipopolysaccharide and peptidoglycan synthesis were confirmed as suitable targets, while other cellular functions, such as energy metabolism pathways, were also suggested for further investigation.
