Coumarin reduces virulence and biofilm formation in Pseudomonas aeruginosa by affecting quorum sensing, type III secretion and C-di-GMP levels [PDF]
, 2018 As one of the major pathogens in wound infections, Pseudomonas aeruginosa produces several virulence factors and forms biofilms; these processes are under the regulation of various quorum sensing (QS) systems.

mBio, 2017 The bacterial second messenger bis-(3′-5′)-cyclic diguanosine monophosphate (c-di-GMP) ubiquitously promotes bacterial biofilm formation. Intracellular pools of c-di-GMP seem to be dynamically negotiated by diguanylate cyclases (DGCs, with GGDEF domains)

Phytohormone-mediated interkingdom signaling shapes the outcome of rice-Xanthomonas oryzae pv. oryzae interactions [PDF]
, 2015 Background: Small-molecule hormones are well known to play key roles in the plant immune signaling network that is activated upon pathogen perception. In contrast, little is known about whether phytohormones also directly influence microbial virulence ...

Bacterial rotary export ATPases are allosterically regulated by the nucleotide second messenger cyclic-di-GMP [PDF]
, 2015 The widespread second messenger molecule cyclic di-GMP (cdG) regulates the transition from motile and virulent lifestyles to sessile, biofilm-forming ones in a wide range of bacteria. Many pathogenic and commensal bacterial-host interactions are known to

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators
Animal Conservation, EarlyView.We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

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.

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.
