Plant-associated bacteria of the genus Xanthomonas cause disease in a wide range of economically important crops. However, their ability to persist in the environment is still poorly understood. Predation by amoebas represents a major selective pressure to bacterial populations in the environment. In this study, we show that the X. citri type 6 secretion system (T6SS) promotes resistance to predation by the soil amoeba Dictyostelium discoideum. We found that an extracytoplasmic function (ECF…

An Extracytoplasmic Function Sigma Factor Required for Full Virulence in Xanthomonas citri pv. citri

A role for EcfL is suggested in the adaptation of X. citri to the plant environment, in this way contributing to its ability to cause citrus canker disease.

The AraC‐type transcription factor TagK is a new player in the signaling cascade that induces the anti‐eukaryotic T6SS of Xanthomonas citri

A singular regulatory circuit consisting of a transmembrane kinase (PknS), an alternative sigma factor (EcfK) and an AraC‐type transcriptional regulator (TagK) promotes expression of the X. citri T6SS in response to a protozoan predator.

Bactericidal type IV secretion system homeostasis in Xanthomonas citri

It is shown that the chromosomal virB operon, which encodes the entirety of structural genes of the T4SS in X. citri, is regulated by the global regulator CsrA, and is constitutively produced at a low basal level, even during low nutrient conditions, despite representing a significant metabolic burden to the cell.

Characterization of Type VI Secretion System in Xanthomonas oryzae pv. oryzae and Its Role in Virulence to Rice

T6SS gene clusters in Xoo have been characterized, and its role in virulence to rice was confirmed, with results indicated that hcp in T6SS-2, but not T6 SS-1, was involved in bacterial virulent to rice plants.

Distribution, Function and Regulation of Type 6 Secretion Systems of Xanthomonadales

In silico predictions identified a series of proteins with known toxic domains as putative T6SS effectors, suggesting that the T6 SSs of Xanthomonadales display both anti-prokaryotic and anti-eukaryotic properties depending on the phylogenetic group and bacterial species.

The Xanthomonas citri pv. citri Type VI Secretion System is Induced During Epiphytic Colonization of Citrus

This work shows that T6SS genes and the cognate positive regulator ecfK are upregulated during growth in the plant surface (epiphytic) and maintain low expression levels during growth inside plant mesophyll and suggests the presence of an environmental signal that triggers the resistance phenotype.

The type VI secretion system of Xanthomonas phaseoli pv. manihotis is involved in virulence and in vitro motility

The phylogenetic analyses suggest that the T6SS might have been acquired by a very ancient event of horizontal gene transfer and maintained through evolution, hinting at their importance for the adaptation of Xanthomonas to their hosts.

A Quorum Sensing-Regulated Type VI Secretion System Containing Multiple Nonredundant VgrG Proteins Is Required for Interbacterial Competition in Chromobacterium violaceum

Characterization of single and multiple vgrG mutants revealed that, despite having high sequence similarity, the six VgrGs show little functional redundancy, with VgrG3 showing a major role in T6SS function, and this results shed light on a key contact-dependent killing mechanism used by C. violaceum to antagonize other bacteria.

The HrpG/HrpX Regulon of Xanthomonads—An Insight to the Complexity of Regulation of Virulence Traits in Phytopathogenic Bacteria

Advances made in understanding the regulatory networks that control and are controlled by the HrpG/HrpX regulon are covered and their conservation between different Xanthomonas spp.

Transcriptional regulator Sar regulates the multiple secretion systems in Xanthomonas oryzae

It is demonstrated that transcriptional regulator Sar (PXO_RS20790) regulates multiple secretion systems and virulence, and it is revealed that only T6SS‐2 is involved in interbacterial competition.



A TonB-dependent transducer is responsible for regulation of pathogenicity-related genes in Xanthomonas axonopodis pv. citri

The results suggest that XAC4131 controls the expression of hrpG indirectly, probably via rpoEXAC4129 and XAC4130 and seems to be regulated by the Fur protein.

Hcp2, a Secreted Protein of the Phytopathogen Pseudomonas syringae pv. Tomato DC3000, Is Required for Fitness for Competition against Bacteria and Yeasts

The results suggest that the T6SS of P. syringae may play an important role in bacterial fitness, allowing this plant pathogen to survive under conditions where it has to compete with other microorganisms for resources.

Regulation of Type VI Secretion Gene Clusters by σ54 and Cognate Enhancer Binding Proteins

Using in vitro binding experiments and in vivo reporter fusion assays, it is shown that the expression of several T6SS gene clusters is dependent on both σ(54) and bEBPs, which are found in the genomes of most species of gram-negative bacteria.

Vibrio cholerae Requires the Type VI Secretion System Virulence Factor VasX To Kill Dictyostelium discoideum

Evidence is presented that VasH regulates the production of a newly identified protein, VasX, which in turn requires a functional T6SS for secretion, and as a V. cholerae mutant lacking vasX exhibits a phenotype of attenuated virulence toward Dictyostelium discoideum.

A Novel Sensor Kinase-Response Regulator Hybrid Controls Biofilm Formation and Type VI Secretion System Activity in Burkholderia cenocepacia

Data show that AtsR is involved in the regulation of genes required for virulence in B. cenocepacia K56-2, including genes encoding a T6SS, which is required for infection in vivo.

Structure-Function Analysis of the HrpB2-HrcU Interaction in the Xanthomonas citri Type III Secretion System

It is shown that the highly conserved HrpB2 C-terminus is essential for T3SS-dependent development of citrus canker symptoms in planta and that an intact and cleavable NPTH site in HrcU is necessary for total functionally of T3 SS in X. citri.

Burkholderia Type VI Secretion Systems Have Distinct Roles in Eukaryotic and Bacterial Cell Interactions

The data show that T6SSs within a single organism can have distinct functions in eukaryotic versus bacterial cell interactions, and are likely to be a decisive factor in the survival of bacterial cells of one species in intimate association with those of another, such as in polymicrobial communities present both in the environment and in many infections.

Genetic Analysis of Anti-Amoebae and Anti-Bacterial Activities of the Type VI Secretion System in Vibrio cholerae

This study systematically mutagenized each individual gene in T6SS locus and characterized their functions based on expression and secretion of the hemolysin co-regulated protein, virulence towards amoebae of Dictyostelium discoideum and killing of Escherichia coli bacterial cells.

Bacteria causing important diseases of citrus utilise distinct modes of pathogenesis to attack a common host

The current knowledge on three pathogens that exhibit distinct tissue specificity and modes of pathogenesis in citrus plants are summarized.

Analysis of the Streptomyces coelicolor sigE gene reveals the existence of a subfamily of eubacterial RNA polymerase sigma factors involved in the regulation of extracytoplasmic functions.

The predicted sequence of sigma E shows greatest similarity to sequences of seven other proteins that define a subfamily of eubacterial RNA polymerase factors sufficiently different from other sigma s that, in many cases, they are not identified by standard similarity searching methods.
