Two Type VI Secretion Systems of Enterobacter cloacae Are Required for Bacterial Competition, Cell Adherence, and Intestinal Colonization

Frontiers in Microbiology, 2020
Enterobacter cloacae has emerged as an opportunistic pathogen in healthcare-associated infections. Analysis of the genomic sequences of several E. cloacae strains revealed the presence of genes that code for expression of at least one type VI secretion ...

Ralstonia pseudosolanacearum PhcQ Controls Quorum Sensing‐Dependent Phenotypes by Binding PhcA and Maintaining Its Protein Stability

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
PhcQ is a key intermediary stabiliser of PhcA controlling quorum sensing‐dependent phenotypes by maintaining protein stability of PhcA. It is downstream of PhcB and upstream of PhcA in the QS regulatory cascade. It binds to PhcA; deletion of a disordered tail in the PhcA C‐terminus impairs its binding affinity.

T6SS in plant pathogens: unique mechanisms in complex hosts

Infection and Immunity
ABSTRACT Type VI secretion systems (T6SSs) are complex molecular machines that allow bacteria to deliver toxic effector proteins to neighboring bacterial and eukaryotic cells. Although initial work focused on the T6SS as a virulence mechanism of human pathogens, the field shifted to examine the use of ...

Virulence of a T6SS Campylobacter jejuni chicken isolate from North Romania [PDF]

BMC Research Notes, 2019
In this study we have investigated the in vitro and in vivo virulence characteristics of a new T6SS positive Campylobacter jejuni chicken isolate (SV12) originating from a poultry population in North Romania. A detailed phenotypic characterization was performed and compared to the T6SS negative C. jejuni 81-176 wild strain.Our results indicate that the

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, Volume 600, Issue 11, Page 1589-1604, June 2026.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Solving the puzzle: connecting a heterologous Agrobacterium tumefaciens T6SS effector to a Pseudomonas aeruginosa spike complex [PDF]

, 2020
The type VI secretion system (T6SS) is a contractile injection apparatus that translocates a spike loaded with various effectors directly into eukaryotic and prokaryotic target cells.

Chitin-induced T6SS in Vibrio cholerae is dependent on ChiS activation

Microbiology, 2018
Vibrio cholerae regularly colonizes the chitinous exoskeleton of crustacean shells in the aquatic region. The type 6 secretion system (T6SS) in V. cholerae is an interbacterial killing device. This system is thought to provide a competitive advantage to V. cholerae in a polymicrobial community of the aquatic region under nutrient-poor conditions.

The Roles of Two Type VI Secretion Systems in Cronobacter sakazakii ATCC 12868

Frontiers in Microbiology, 2018
The type VI secretion system (T6SS), which has been found in 25% of gram-negative bacteria, is a crucial virulence factor in several pathogens. Although T6SS gene loci have been discovered in Cronobacter species, one of the major opportunistic foodborne ...

Functionally complementary bacterial inoculant coordinates arbuscular mycorrhizal fungi to improve Angelica sinensis root yield and quality

iMetaOmics, Volume 3, Issue 2, June 2026.
Comprehensive understanding of how diverse PGPR strains enhance the rhizosphere microenvironment remains a considerable challenge. Here, we provide experimental evidence that a functionally synergistic composite microbial formulation can markedly enhance growth performance and improve the quality attributes in Angelica sinensis.
