Expression of a Yersinia pseudotuberculosis Type VI Secretion System Is Responsive to Envelope Stresses through the OmpR Transcriptional Activator. [PDF]
PLoS ONE, 2013 The Type VI secretion system (T6SS) is a macromolecular complex widespread in Gram-negative bacteria. Although several T6SS are required for virulence towards host models, most are necessary to eliminate competitor bacteria.

Divergent control of RpoN on H2-T6SS and H3-T6SS.
, 2013 The expression of H2-T6SS (A), H3-T6SS left (B), and H3-T6SS right (C) after 7 hours (A), or 9 hours (B & C) of growth at 37°C in the WT strain (blue bars), in a PAO1ΔrpoN mutant complemented strain (green bars, PAO6360 strain) or the PAO1 ΔrpoN mutant ...

Genetically complemented V. coralliilyticus T6SS mutant challenge assay.
, 2020 The V. coralliilyticus OCN008 ΔvasK strain (T6SS-) and the ΔvasK strain carrying a plasmid expressing a wild-type copy of vasK (pBU270) were challenged against T6SS+ V. cholerae (black bars) or T6SS+ V. cholerae (grey bars). V. cholerae strains were also

Calcium Promotes T6SS-Mediated Killing and Aggregation between Competing Symbionts
Microbiology Spectrum, 2022 Microbes deploy competitive mechanisms to gain access to resources such as nutrients or space within an ecological niche. Identifying when and where these strategies are employed can be challenging given the complexity and variability of most natural systems; therefore, studies evaluating specific cues that conditionally regulate interbacterial ...

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.A newly identified virulence family from Pectobacterium parvum that binds plant defensive compounds (e.g., solanidine) with high affinity enhances bacterial tolerance and is required for full virulence. This trade‐off between defence and growth reveals a key host‐adaptation strategy.

Pantoea ananatis Utilizes a Type VI Secretion System for Pathogenesis and Bacterial Competition
Molecular Plant-Microbe Interactions, 2015 Type VI secretion systems (T6SSs) are a class of macromolecular machines that are recognized as an important virulence mechanism in several gram-negative bacteria.

OxyR directly activates T6SS-4 expression.
, 2015 A. OxyR binds the T6SS-4 promoter. Biotin-labeled probe or its mutant was incubated with OxyR. The protein-DNA complexes were detected by streptavidin-conjugated HRP and chemiluminescent substrate.
