Comparative Phylogenomic Analysis Reveals Evolutionary Genomic Changes and Novel Toxin Families in Endophytic Liberibacter Pathogens

Microbiology Spectrum, 2021
Liberibacter pathogens are the causative agents of several severe crop diseases worldwide, including citrus Huanglongbing and potato zebra chip. These bacteria are endophytic and nonculturable, which makes experimental approaches challenging and ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Genomic analysis of prophages in 44 clinical strains of Pseudomonas aeruginosa isolated in Saudi Arabia

Frontiers in Cellular and Infection Microbiology
Prophages are bacteriophages that integrate their genomes into the bacterial chromosome. This research aimed to analyze and characterize prophages integrated into 44 Pseudomonas aeruginosa strains isolated from tertiary hospitals in Saudi Arabia. A total

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

An Efficient, Counter-Selection-Based Method for Prophage Curing in Pseudomonas aeruginosa Strains

Viruses, 2021
Prophages are bacteriophages in the lysogenic state, where the viral genome is inserted within the bacterial chromosome. They contribute to strain genetic variability and can influence bacterial phenotypes. Prophages are highly abundant among the strains

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.

The impact of prophages on bacterial chromosomes [PDF]

Molecular Microbiology, 2004
SummaryProphages were automatically localized in se‐quenced bacterial genomes by a simple semantic script leading to the identification of 190 prophages in 115 investigated genomes. The distribution of prophages with respect to presence or absence in a given bacterial species, the location and orientation of the prophages on the replichore was not ...

AcrIIA8 is a putative phage structural protein of the HTJ2 family that does not inhibit Streptococcus pyogenes Cas9

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Anti‐CRISPR (Acr) proteins are phage‐encoded anti‐defense factors that suppress CRISPR‐Cas immunity in bacteria. AcrIIA8 was previously identified as an inhibitor of Streptococcus pyogenes Cas9 (SpyCas9) through functional assays of metagenomic libraries. Here, we report that AcrIIA8 does not inhibit SpyCas9 in biochemical assays under a range

Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

Advanced Science, Volume 13, Issue 31, 4 June 2026.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...

Deciphering Active Prophages from Metagenomes

mSystems, 2022
Temperate phages (prophages) are ubiquitous in nature and persist as dormant components of host cells (lysogenic stage) before activating and lysing the host (lytic stage). Actively replicating prophages contribute to central community processes, such as
