Cyclic di‐GMP inactivates T6SS and T4SS activity in Agrobacterium tumefaciens [PDF]

Molecular Microbiology, 2019
Summary The Type VI secretion system (T6SS) is a bacterial nanomachine that delivers effector proteins into prokaryotic and eukaryotic preys. This secretion system has emerged as a key player in regulating the microbial diversity in a population. In the plant pathogen Agrobacterium tumefaciens

Phenotypical and Genomic Characterization of the Mollusk Pathogen Francisella halioticida

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Phenotypic and genetic characterization of French isolates of Francisella halioticida and comparison with Canadian and Japanese strains. The study revealed similarities between FR22s and previous isolates but distinct differences with FR21. A major finding is the absence of the Francisella pathogenicity island in the less virulent isolate, FR22b ...

Evidence of Extensive DNA Transfer between Bacteroidales Species within the Human Gut [PDF]

, 2014
The genome sequences of intestinal Bacteroidales strains reveal evidence of extensive horizontal gene transfer. In vitro studies of Bacteroides and other bacteria have addressed mechanisms of conjugative transfer and some phenotypic outcomes of these DNA

Characterization of type VI secretion systems (T6SS) of endosymbionts from mimosa or lupine [PDF]

, 2017
The T6SS is a nanosyringe that injects proteins into prokaryotic or eukaryotic cells, and it is encoded in the genomes of more than 25% of Gram-negative bacteria (1). We are studying the T6SS of Rhizobium etli Mim1 and Bradyrhizobium sp.

Genomic and Functional Characterisation of Endophytic Bacterium Bacillus Cereus Strain E1 Alleviating Salt Stress and Enhancing Tomato Physiology and Spectral Indices

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Mangroves in arid environments represent unique ecological niches that support a diverse range of microorganisms. Endophytic bacteria residing within host plants play a crucial role in promoting plant growth by enhancing pathogen resistance and alleviating environmental stress.

Virulence characteristics of hcp (+) Campylobacter jejuni and Campylobacter coli isolates from retail chicken. [PDF]

, 2015
BACKGROUND: Recently the Type VI secretion system (T6SS), which can play a significant role in bacterial survival and pathogenesis, was reported in Campylobacter spp., having the hcp gene as a key component. METHODS: Campylobacteriosis is associated with

BSocial Tool Deciphers Highly Functional Plant Growth‐Promoting Bacterial Consortia

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
The use of the online tool BSocial can be used to decipher microbial social behaviour and select highly functional plant growth‐promoting consortia. Positive correlations are observed between species richness within the consortia and plant growth‐promoting traits such as phosphate solubilisation and indole acetic acid and siderophore production ...
