Unusual Metabolism and Hypervariation in the Genome of a Gracilibacterium (BD1-5) from an Oil-Degrading Community. [PDF]

, 2019
The candidate phyla radiation (CPR) comprises a large monophyletic group of bacterial lineages known almost exclusively based on genomes obtained using cultivation-independent methods.

FimX, a multidomain protein connecting environmental signals to twitching motility in Pseudomonas aeruginosa [PDF]

, 2003
Twitching motility is a form of surface translocation mediated by the extension, tethering, and retraction of type IV pili. Three independent Tn5-B21 mutations of Pseudomonas aeruginosa with reduced twitching motility were identified in a new locus which

Photophobotaxis of single‐celled and filamentous cyanobacteria

Photochemistry and Photobiology, EarlyView.
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, Volume 600, Issue 11, Page 1589-1604, June 2026.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

In situ structures of the genome and genome-delivery apparatus in a single-stranded RNA virus. [PDF]

, 2016
Packaging of the genome into a protein capsid and its subsequent delivery into a host cell are two fundamental processes in the life cycle of a virus. Unlike double-stranded DNA viruses, which pump their genome into a preformed capsid, single-stranded ...

Involvement of Type IV Pili in Pathogenicity of Plant Pathogenic Bacteria

Genes, 2011
Type IV pili (T4P) are hair-like appendages found on the surface of a wide range of bacteria belonging to the β-, γ-, and δ-Proteobacteria, Cyanobacteria and Firmicutes. They constitute an efficient device for a particular type of bacterial surface motility, named twitching, and are involved in several other bacterial activities and functions ...

Variation in the Oxidative State of Collared Flycatcher (Ficedula albicollis) Nestlings and Its Association With Their Plumage Coloration

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Plumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).

Heterogeneity in Surface Sensing Suggests a Division of Labor in Pseudomonas aeruginosa Populations [PDF]

, 2019
The second messenger signaling molecule cyclic diguanylate monophosphate (c-di-GMP) drives the transition between planktonic and biofilm growth in many bacterial species.

Cultivation of Electrogens With Cost‐Effective Membrane‐Less Bioreactor Designs

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT Rational improvements in bioreactor design for scaling up power generation in microbial fuel cells (MFCs) are discussed in this study. The potential of autoclavable MFCs for isolating electroactive bacteria that produce sustainable electricity is being investigated.
