High levels of cyclic-di-GMP in plant-associated Pseudomonas correlate with evasion of plant immunity [PDF]

, 2016
The plant innate immune system employs plasma membrane-localized receptors that specifically perceive pathogen/microbe-associated molecular patterns (PAMPs/MAMPs).

The Diverse Roles of the Histone‐Like Nucleoid Structuring (H‐NS) Protein in Vibrio parahaemolyticus

Genetics Research , Volume 2026, Issue 1, 2026.
The histone‐like nucleoid structuring (H‐NS) protein is a global transcriptional regulator critical for bacterial genome organization and gene expression. In Vibrio parahaemolyticus, H‐NS represses virulence factors such as thermostable direct hemolysin (TDH), type III secretion systems (T3SS1/T3SS2), and type VI secretion systems (T6SS1/T6SS2).

Identification of the core c-di-GMP turnover proteins responsible for root colonization of Bacillus velezensis

iScience, 2022
Summary: Root colonization by beneficial rhizobacteria determines their plant beneficial effects. The messenger c-di-GMP is involved in the bacterial transition process between motility and biofilm, which are crucial to the colonization ability of the ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Genetic Determinants Associated With the Biofilm Formation Impairment in Pseudomonas aeruginosa Clinical Isolates

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Numerous studies have reported biofilm formation impairment in Pseudomonas aeruginosa clinical isolates, however, the genetic basis of this phenomenon remains largely unexplored. In this study, we aimed to identify associations between impaired‐biofilm formation and loss‐of‐function mutations in biofilm regulatory and effector genes.

The Structure of an Unconventional HD-GYP Protein from Bdellovibrio Reveals the Roles of Conserved Residues in this Class of Cyclic-di-GMP Phosphodiesterases

mBio, 2011
Cyclic-di-GMP is a near-ubiquitous bacterial second messenger that is important in localized signal transmission during the control of various processes, including virulence and switching between planktonic and biofilm-based lifestyles.

Diguanylate Cyclases in Vibrio cholerae: Essential Regulators of Lifestyle Switching

Frontiers in Cellular and Infection Microbiology, 2020
Biofilm formation in Vibrio cholerae empowers the bacteria to lead a dual lifestyle and enhances its infectivity. While the formation and dispersal of the biofilm involves multiple components—both proteinaceous and non-proteinaceous, the key to the ...

Characterisation of Variants of Cyclic di-GMP Turnover Proteins Associated with Semi-Constitutive rdar Morphotype Expression in Commensal and Uropathogenic Escherichia coli Strains

Microorganisms, 2023
Expression of rdar (red, dry, and rough) colony morphology-based biofilm formation in Escherichia coli is highly variable. To investigate the molecular mechanisms of semi-constitutive rdar morphotype formation, we compared their cyclic di-GMP turnover ...

AmrZ is a major determinant of c-di-GMP levels in Pseudomonas fluorescens F113 [PDF]

, 2018
The transcriptional regulator AmrZ is a global regulatory protein conserved within the pseudomonads. AmrZ can act both as a positive and a negative regulator of gene expression, controlling many genes implicated in environmental adaption.
