GENERALIZED TRANSDUCTION IN CAULOBACTER CRESCENTUS [PDF]

open access: yesGenetics, 1977
ABSTRACT Two closely related bacteriophage, φCr30 and φCr35, are the first bacteriophage shown to mediate generalized transduction in Caulobacter crescentus. Unlike most other transducing phage, they are virulent and do not form any sort of lysogenic relationship with their host.

Caulobacter crescentus Adapts to Phosphate Starvation by Synthesizing Anionic Glycoglycerolipids and a Novel Glycosphingolipid

open access: yesmBio, 2019
Caulobacter crescentus adapts to phosphate starvation by elongating its cell body and a polar stalk structure. The stalk is an extension of the Gram-negative envelope containing inner and outer membranes as well as a peptidoglycan cell wall.

Regulation of tryptophan biosynthesis in Caulobacter crescentus [PDF]

open access: yesJournal of Bacteriology, 1988
We present an analysis of the expression of the trpE gene and the trpFBA operon in the dimorphic bacterium Caulobacter crescentus. The catalytic activity of component I of anthranilate synthase, the product of the trpE gene, was efficiently inhibited by tryptophan, the end product of the pathway, which suggests that tryptophan biosynthesis is likely ...

OmpW of Caulobacter crescentus Functions as an Outer Membrane Channel for Cations. [PDF]

open access: yesPLoS ONE, 2015
Caulobacter crescentus is an oligotrophic bacterium that lives in dilute organic environments such as soil and freshwater. This bacterium represents an interesting model for cellular differentiation and regulation because daughter cells after division ...

The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

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

open access: yesJournal 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.

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species

open access: yes, 2011
Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

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

open access: yesJournal 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.

Biowaste Composting as a Sustainable Platform for Bacterial CO Production: Evidence From cooS Gene Expression and Microbial Community Profiling

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates, for the first time, the expression of the cooS gene during composting, confirming microbial CO production under mesophilic conditions. The results highlight composting as a novel waste‐to‐biochemicals process, offering a sustainable, low‐carbon pathway for generating carbon monoxide via bacterial CO dehydrogenase activity ...

Gut Microbiota‐Derived Anandamide Mediates the Therapeutic Effects of Urolithin A on Alcohol‐Induced Cognitive and Social Dysfunction via CB1R‐DRD2‐RAP1 Signaling Axis

open access: yesAdvanced Science, Volume 13, Issue 20, 9 April 2026.
This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...
