SpoT-mediated reduction of (p)ppGpp levels promotes Ralstonia pseudosolanacearum adaptation to both plant xylem and legume nodules

This study demonstrates that adaptive mutations in the *spoT* gene, which lower basal (p)ppGpp levels, enable *Ralstonia pseudosolanacearum* to efficiently adapt to both plant xylem and legume nodules by enhancing nutrient utilization and growth without compromising its virulence.

A 16S rRNA gene-based analysis of microbial communities in compost-bedded pack barns from dairy farms in Argentina.

This study utilized 16S rRNA gene sequencing to characterize and compare the bacterial community structures of compost-bedded pack barns on two dairy farms in Argentina, revealing that while both systems were dominated by typical compost-associated phyla, their specific community compositions differed based on distinct management practices and initial bedding conditions.

Gut Microbiome Alterations in Canine Idiopathic Epilepsy: A Pairwise Case-Control Study

This pairwise case-control study of 98 dogs reveals that while household environment is the primary driver of gut microbiome variation, idiopathic epilepsy is associated with a modest but significant shift in microbial community structure, specifically characterized by a consistent increase in *Collinsella* abundance.

Integrated analysis reveals strong reproducible signals within and across studies of the built environment

By integrating four diverse 16S rRNA datasets and applying a unified sampling ontology, this study demonstrates that the built environment microbiome exhibits strong, reproducible signals characterized by distinct soil-associated taxa on floors and human-associated taxa on hands and surfaces, which persist across different buildings, timepoints, and sequencing protocols without the need for batch correction.

Nucleolar Targeting and ROS-dependent inhibition of rRNA synthesis by Epstein-Barr Virus Nuclear Antigen 1

This study reveals that Epstein-Barr virus nuclear antigen 1 (EBNA-1) utilizes a cell cycle-dependent bipartite nucleolar localization signal to interact with the host protein EBP2, thereby inducing reactive oxygen species that suppress ribosomal RNA synthesis and global protein production, a mechanism potentially linked to viral-driven cell survival and transformation.

Plasmodium Protein Kinase 2 is required for ookinete to oocyst transition, and parasite transmission by the mosquito.

This study demonstrates that Plasmodium Protein Kinase 2 (PK2) is essential for the parasite's transmission by the mosquito, specifically governing the ookinete-to-oocyst transition and subsequent sporozoite development through mechanisms involving altered microneme positioning and phosphorylation-mediated regulation of parasite architecture and gene expression.
