Osmotic stress response of the coral and oyster pathogen Vibrio coralliilyticus: acquisition of catabolism gene clusters for the compatible solute and signaling molecule myo-inositol

This study identifies myo-inositol catabolism gene clusters in Vibrio coralliilyticus and related bacteria, showing their role in osmotic stress response and potential impact on coral-algae symbiosis.

Regulators H-NS and LeuO inversely control swarming motility and biofilm formation in Vibrio parahaemolyticus

This paper shows H-NS inhibits swarming motility and promotes biofilm formation in Vibrio parahaemolyticus, with LeuO acting as an antagonist to H-NS.

NhaR, LeuO and H-NS are part of an expanded regulatory network for ectoine biosynthesis expression

This study identifies LeuO as a positive and NhaR as a negative regulator of ectoine biosynthesis in Vibrio parahaemolyticus, revealing their roles in osmotic stress response.

A class IV adenylate cyclase CyaB is required for capsule polysaccharide production and biofilm formation in Vibrio parahaemolyticus

This study identifies CyaB, a class IV adenylate cyclase in Vibrio parahaemolyticus, as essential for capsule polysaccharide production and biofilm formation, contrasting with its role in V. cholerae.

Regulatory small RNA, Qrr2, is expressed independently of sigma factor-54 and functions autonomously in Vibrio parahaemolyticus to control quorum sensing

This study identifies Qrr2 as an autonomous regulatory sRNA in Vibrio parahaemolyticus that controls OpaR independently of sigma factor-54, revealing a conserved dual-promoter mechanism for qrr2 expression.

The organosulfur compound dimethylsulfoniopropionate (DMSP) is utilized as an osmoprotectant by Vibrio species

This study shows Vibrio species use DMSP as an osmoprotectant and identifies specific BCCT transporters involved in its uptake.

Fis connects two sensory pathways, quorum sensing and surface sensing, to control motility in Vibrio parahaemolyticus

This paper shows Fis regulates quorum sensing and surface sensing pathways in V. parahaemolyticus to control motility and metabolism, with Fis deletion leading to reduced swarming and fitness.

Investigations of dimethylglycine (DMG), glycine betaine and ectoine uptake by a BCCT family transporter with broad substrate specificity in Vibrio species.

This study identifies dimethylglycine (DMG) as a novel osmolyte for Vibrio parahaemolyticus and shows it is transported by BCCT-family carriers, with BccT1 facilitating uptake of DMG, glycine betaine, and ectoine.

L-ascorbic acid (vitamin C) fermentation by the human pathogen Vibrio cholerae

This paper shows that Vibrio cholerae can ferment L-ascorbate as an energy source using the Ula system, with ulaG and a pyridoxal phosphate phosphatase being essential for this process.

CosR is a repressor of compatible solute biosynthesis and transporter systems

This study identifies CosR as a repressor of compatible solute biosynthesis and transporter systems in Vibrio parahaemolyticus and shows its conservation across Vibrio species.

Chromatic Bacteria - A broad host-range plasmid and chromosomal insertion toolbox for fluorescent protein expression in bacteria

The paper develops plasmids and transposons for fluorescent protein expression in bacteria, enabling differential labeling for studying microbial interactions.
