An RNA degradosome assembly in Caulobacter crescentus [PDF]

Nucleic Acids Research, 2010
In many bacterial species, the multi-enzyme RNA degradosome assembly makes key contributions to RNA metabolism. Powering the turnover of RNA and the processing of structural precursors, the RNA degradosome has differential activities on a spectrum of transcripts and contributes to gene regulation at a global level.

Contact-dependent killing by Caulobacter crescentus via cell surface-associated, glycine zipper proteins

eLife, 2017
Most bacteria are in fierce competition with other species for limited nutrients. Some bacteria can kill nearby cells by secreting bacteriocins, a diverse group of proteinaceous antimicrobials.

Diversity and distribution of bacterial phytases

iMetaOmics, Volume 3, Issue 2, June 2026.
Phytases: The stepwise dephosphorylation of phytate is catalyzed by phytases, a group of enzymes found mainly among bacteria and plants. Bacterial potential: We identified an unexpectedly widespread and previously underappreciated bacterial potential for phytate dephosphorylation, suggesting that microbial phytases play crucial roles in the ...

Regulation of the Caulobacter crescentus dnaKJ operon [PDF]

Journal of Bacteriology, 1995
The bacterial heat shock proteins DnaK and DnaJ are members of a class of molecular chaperones that are required for a wide variety of cellular functions at normal growth temperatures. In Caulobacter crescentus, the expression of the dnaKJ operon is regulated both temporally during the normal cell cycle and by heat shock. Analysis of deletions and base

Enterococcus faecalis Extracellular Vesicles Deliver the Bacterial GTPase Obg to Hijack mTOR Signalling in Hepatocellular Carcinoma

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
E. faecalis is enriched in HCC tissue and can promote liver tumourigenesis by activating mTOR signalling pathway. Obg derived from E. faecalis extracellular vesicles (EVs) is a GTPase physically interacts with mTOR, and acts as an interkingdom activator of mTOR. EF‐Obg expression level in HCC tissue correlates with poor prognosis in HCC patients.

Gene network analysis identifies a central post-transcriptional regulator of cellular stress survival

eLife, 2018
Cells adapt to shifts in their environment by remodeling transcription. Measuring changes in transcription at the genome scale is now routine, but defining the functional significance of individual genes within large gene expression datasets remains a ...

Infectious hematopoietic necrosis virus (IHNV) in fish and its consequences for fish farming: A comprehensive review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Viral diseases are a major concern in finfish aquaculture, leading to severe health problems. Infectious hematopoietic necrosis (IHN) is a highly transmissible systemic viral disease that primarily affects salmonids, causing significant mortality and economic losses to the salmonid farming industry.

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3876-3896, June 2026.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

Caulobacter crescentus: model system extraordinaire

Current Biology, 2020
In scientific research, we often rely on well-established model systems to tackle important questions. In this context, extensive characterization of specific bacterial species such as Escherichia coli and Bacillus subtilis has provided a vast amount of knowledge that extends well beyond the biology of these two organisms.
