Bacterial type VI secretion system augments resistance against biotic and abiotic stress [PDF]

BIO Web of Conferences
In their natural environment, bacteria employ various mechanisms to survive and protect themselves from neighboring microorganisms. One of the most noteworthy features found in a minority approximately 25% of Gram-negative species, predominantly those ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

The RIX domain defines a class of polymorphic T6SS effectors and secreted adaptors

Nature Communications, 2023
Abstract Bacteria use the type VI secretion system (T6SS) to deliver toxic effectors into bacterial or eukaryotic cells during interbacterial competition, host colonization, or when resisting predation. Identifying effectors is a challenging task, as they lack canonical secretion signals or universally conserved ...

The Tip of the VgrG Spike Is Essential to Functional Type VI Secretion System Assembly in Acinetobacter baumannii

mBio, 2020
The type VI secretion system (T6SS) is a critical weapon in bacterial warfare between Gram-negative bacteria. Although invaluable for niche establishment, this machine represents an energetic burden to its host bacterium.

Thirteen‐year genomic analysis (2010–2022) reveals high‐risk ICU Pseudomonas aeruginosa in China

mLife, Volume 5, Issue 4, Page 459-472, August 2026.
Abstract Pseudomonas aeruginosa is a significant opportunistic pathogen, particularly prevalent in intensive care units (ICUs). Through a comprehensive genomic and phenotypic analysis of 518 ICU and healthy isolates collected over a 13‐year period (2010–2022), we found that ICU strains, despite reduced sequence type (ST) diversity, are dominated by ...

Baseplate Component TssK and Spatio-Temporal Assembly of T6SS in Pseudomonas aeruginosa [PDF]

Frontiers in Microbiology, 2019
The Gram-negative bacteria use the contractile multi-molecular structure, called the Type VI Secretion System (T6SS) to inject toxic products into eukaryotic and prokaryotic cells. In this study, we use fluorescent protein fusions and time-lapse microscopy imaging to study the assembly dynamics of the baseplate protein TssK in Pseudomonas aeruginosa ...

ClpV3 of the H3-Type VI Secretion System (H3-T6SS) Affects Multiple Virulence Factors in Pseudomonas aeruginosa

Frontiers in Microbiology, 2020
The type VI secretion system (T6SS) is a toxic effector delivery apparatus widely distributed in Gram-negative bacteria. The opportunistic pathogen Pseudomonas aeruginosa encodes three T6SSs, namely H1-, H2-, and H3-T6SS.

Characterization of multiple type-VI secretion system (T6SS) VgrG proteins in the pathogenicity and antibacterial activity of porcine extra-intestinal pathogenic Escherichia coli

Virulence, 2019
Porcine extra-intestinal pathogenic Escherichia coli (ExPEC) causes great economic losses to the pig industry and poses a serious threat to public health worldwide. Some secreted virulence factors have been reported to be involved in the pathogenicity of
