New Phytologist, Volume 247, Issue 4, Page 1805-1825, August 2025.Summary Cyanobacteria are major components of biofilms in light‐exposed environments, contributing to nutrient cycling, nitrogen fixation and global biogeochemical processes. Although nitrogen‐fixing cyanobacteria have been successfully used in biofertilization, the regulatory mechanisms underlying biofilm formation remain poorly understood.

ChemBioChem, Volume 26, Issue 7, April 1, 2025.GSPII‐A is the first of three consecutive GSPII domains of PilF from Thermus thermophilus and the only one that does not bind c‐di‐GMP. In this study we solve the structure of GSPII‐A and show the key factors hindering c‐di‐GMP binding. Through mutagenesis, we elucidate the minimal motif conservation needed for c‐di‐GMP recognition. Abstract The cyclic

Formation and dimerization of the phosphodiesterase active site of the Pseudomonas aeruginosa MorA, a bi-functional c-di-GMP regulator [PDF]
, 2014 Diguanylate cyclases (DGC) and phosphodiesterases (PDE) respectively synthesise and hydrolyse the secondary messenger cyclic dimeric GMP (c-di-GMP), and both activities are often found in a single protein.

Study of GGDEF-EAL proteins in c-di-GMP pathways in Xanthomonas citri subsp. citri
, 2015 Segundos mensageiros nucleotídicos são amplamente utilizados por bactérias para se adaptar às mudanças ambientais e fisiológicas. Neste cenário destaca-se o c-di-GMP, um segundo mensageiro praticamente universal em bactérias responsável por controlar a ...

Co‐Existence Slows Diversification in Experimental Populations of E. coli and P. fluorescens
Environmental Microbiology, Volume 27, Issue 2, February 2025.Escherichia coli and Pseudomonas fluorescens were cultured in monoculture and co‐culture for 8 weeks. Both species diversified in monoculture, while sequencing revealed mutations in P. fluorescens that were enriched in co‐culture with E. coli. A sequencing‐based invasion assay of 16S amplicons revealed that mutations in the PFLU_1661 gene confer the ...

Cyclic di-GMP-dependent signaling pathways in the pathogenic Firmicute Listeria monocytogenes.
PLoS Pathogens, 2014 We characterized key components and major targets of the c-di-GMP signaling pathways in the foodborne pathogen Listeria monocytogenes, identified a new c-di-GMP-inducible exopolysaccharide responsible for motility inhibition, cell aggregation, and ...

A systematic analysis of the role of GGDEF-EAL domain proteins in virulence and motility in Xanthomonas oryzae pv. oryzicola [PDF]
, 2016 The second messenger c-di-GMP is implicated in regulation of various aspects of the lifestyles and virulence of Gram-negative bacteria. Cyclic di-GMP is formed by diguanylate cyclases with a GGDEF domain and degraded by phosphodiesterases with either an ...

Asymmetric activation mechanism of a homodimeric red light-regulated photoreceptor
eLife, 2018 Organisms adapt to environmental cues using diverse signaling networks. In order to sense and integrate light for regulating various biological functions, photoreceptor proteins have evolved in a modular way.
