Prevalence, Host Range, and Comparative Genomic Analysis of Temperate Ochrobactrum Phages

Frontiers in Microbiology, 2017
Ochrobactrum and Brucella are closely related bacteria that populate different habitats and differ in their pathogenic properties. Only little is known about mobile genetic elements in these genera which might be important for survival and virulence ...

RING E3 ligase SNIPER8 functions redundantly with three close homologs to regulate the turnover of transcriptional co‐repressor TPR1

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis E3 ligase SNIPER8 negatively regulates immunity by promoting ubiquitination and proteasomal degradation of the transcriptional corepressor TOPLESS‐RELATED1, limiting excessive immune responses, maintaining immune homeostasis, and balancing defense activation and normal plant growth.

Bacteriophages and Cryptic Lysogeny in Achromobacter

Journal of General Virology, 1974
Summary The characteristics of 4 closely related bacteriophages of halotolerant, collagenolytic strains of Achromobacter isolated from cured hides are described. All phages cause lysogenic conversion. Achromobacter sp. 2 is shown to be a cryptic lysogen for phage α3 and has a low rate of spontaneous liberation which can be increased by treatment with ...

Viruses, Periodontitis, and Systemic Diseases

Journal of Periodontal Research, EarlyView.
This narrative review aimed to summarize current evidence on the viral involvement in periodontitis and its relevance for systemic diseases. The oral cavity acts as an active viral reservoir and dissemination platform, where virus–microbiome interactions may promote dysbiosis, periodontitis progression, and systemic inflammatory effects, while the ...

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

Detecting Lactococcus lactis Prophages by Mitomycin C-Mediated Induction Coupled to Flow Cytometry Analysis

Frontiers in Microbiology, 2017
Most analyzed Lactococcus lactis strains are predicted to harbor one or more prophage genomes within their chromosome; however, the true extent of the inducibility and functionality of such prophages cannot easily be deduced from sequence analysis alone.

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Saturating mutagenesis on the Ser118 residue responsible for the spectral tuning mechanism of the orange/green‐reversible cyanobacteriochrome AM1_1499g1

Plant Biology, EarlyView.
This graphical abstract illustrates our systematic site‐saturation mutagenesis at the Ser118 position of the AM1_1499g1 GAF domain. By replacing this single residue, we generated a diverse array of variants with distinct spectral properties, demonstrating the remarkable molecular plasticity of cyanobacteriochromes and their customizability for ...

Role of RIPK1/RIPK3/MLKL signalling pathway in sepsis‐associated acute kidney injury

Experimental Physiology, EarlyView.
Abstract Sepsis‐associated acute kidney injury (SA‐AKI) is a common clinical syndrome in critically ill patients, and its high mortality rate is closely related to complex pathological mechanisms. Existing studies have shown that the pathophysiological process of SA‐AKI involves complex multi‐mechanism interactions, including an uncontrolled systemic ...
