Photophobotaxis in the filamentous cyanobacterium Phormidium lacuna: Mechanisms and implications for photosynthesis‐based light direction sensing

Photochemistry and Photobiology, Volume 100, Issue 5, Page 1290-1309, September/October 2024.
How do filaments of Phormidium lacuna find the lighted area? Each filament moves in random direction. If a filament crosses the light–dark border, it returns and stays in the light. Abstract Cyanobacterium Phormidium lacuna filaments move from dark to illuminated areas by twitching motility.

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.

Structure and Multitasking of the c-di-GMP-Sensing Cellulose Secretion Regulator BcsE

mBio, 2020
Most bacteria respond to surfaces by biogenesis of intracellular c-di-GMP, which inhibits motility and induces secretion of biofilm-promoting adherence factors.

Discrete cyclic di-GMP-dependent control of bacterial predation versus axenic growth in Bdellovibrio bacteriovorus.

PLoS Pathogens, 2012
Bdellovibrio bacteriovorus is a Delta-proteobacterium that oscillates between free-living growth and predation on Gram-negative bacteria including important pathogens of man, animals and plants.

GGDEF-EAL domain proteins in bacterial physiology [Elektronisk resurs]

, 2008
GGDEF and EAL domain proteins were identified in the chromosome of many bacteria. GGDEF domain proteins are generally diguanyl cyclases which synthesize the secondary messenger cyclic di-GMP.

Archaeal genes code for GGDEF domain proteins with diguanylate cyclase activity

A biofilm-like tightly surface-associated mode of growth of pre-cellular life protected by an extracellular matrix has been hypothesized to be a prerequisite for the emergence of cellular life and its persistence under challenging environmental conditions.

Prediction and functional analysis of GGDEF/EAL domaincontaining proteins in Azorhizobium caulinodans ORS571

, 2019
[Objective] c-di-GMP,an important second messenger regulating multiple functions of bacteria,is generally synthesized and hydrolysed by proteins containing GGDEF or EAL domain.In this study,we analyzed the genome-wide GGDEF/EAL domain-containing proteins

Discovery of Novel c-di-GMP-Related Genes in Leptospira interrogans

Pathogens
Cyclic di-GMP (bis-(3′→5′) cyclic dimeric guanosine monophosphate) is a ubiquitous bacterial second messenger that regulates a wide range of cellular processes, including biofilm formation, motility, virulence, and environmental adaptation.
