An analysis of selected secretion systems of Pseudomonas species
Direct secretion systems which deliver molecules from one cell to another have huge significance in shaping bacterial communities or in determining the outcome of bacterial associations with eukaryotic organisms. This work examines the roles of the Type III Secretion System (T3SS) and the Type VI …

Characterizing the advantages of diverse effector secretion in Pseudomonas aeruginosa
In the environment, bacteria exist in complex communities with other bacterial species, where they compete for resources. Cells are frequently in close proximity to one another, and therefore, many bacteria have evolved pathways to intoxicate their neighbors directly. One such pathway is the type …

The role of the Vibrio cholerae Type VI secretion system during kin cell interaction, biofilm formation and priority effects
<p><em>Vibrio cholerae’s </em>Type VI secretion system (T6SS) is one of the arsenals used by the bacteria for its long-term survival in different environments, against a variety of opponents, and for its maintained pathogenicity in vulnerable regions of the world. Therefore, the more we understand …

CHARACTERIZATION OF CA²⁺-MEDIATED VIRULENCE AND MICROBIAL COMPETITION IN THE PLANT PATHOGEN PSEUDOMONAS SYRINGAE
… evolved mechanisms to sense and respond to environmental Ca²⁺ levels, using these signals to fine-tune their physiology and coordinate virulence.Pseudomonas syringae, a model bacterial plant pathogen, uses a sophisticated arsenal of virulence factors, including the type III secretion system …

Dissecting the puncturing device of the Type VI Secretion System: role of Hcp, VgrG and PAAR proteins in assembly and secretion of effectors
The Type VI secretion system (T6SS) is a macromolecular machinery, widespread in Gram negative bacteria, which is used to deliver toxic proteins (“effectors”) directly into target eukaryotic or prokaryotic cells. As a result, this system plays a crucial role both in direct pathogenicity and in …

Specialised Effectors and Accessory Proteins Important in the Antibacterial Type VI Secretion System of <i>Serratia marcescens</i>
Bacteria are often found in polymicrobial environments and, to ensure a fitness advantage, have adopted diverse strategies to fight other microbes within their preferred niche. An important mechanism utilised by Gram-negative bacteria is protein secretion, with bacterial secretion systems …

Analysis of the diverse antibacterial strategies used by <i>Serratia marcescens</i> Db10
… properties, including antibiotics. The activity of NRPS and PKS enzymes is dependent on their modification by a phosphopantetheinyl transferase (PPTase) enzyme. In this work we identify the biosynthetic genes, <i>alb2-6</i>, which are required for the production of the NRPS-PKS antibiotic, …

Exploring Interactions of Phyllosphere Epiphytes with Plant Pathogenic Bacteria Pseudomonas and Xanthomonas on Tomato
… this study uses X. <em>perforans</em> wild-type and X. <em>perforans</em> type VI secretion system (T6SS) mutant strains to observe the role of type VI secretion system in infection with a potential biocontrol agent. To explain interactions among the <em>phyllosphere</em> residents, …

Characterization of Novel Type VI Effectors of Acidovorax citrulli and Their Applicability to Biological Control of Plant Diseases
Bacterial secretion systems have been playing essential roles in modulating the microbiota of most ecological niches. Among a variety of secretion systems, the Type VI Secretion System (T6SS), a nanomachine widely distributed in Gram-negative bacteria, is gaining increasing attention due to its …
