Visualization of the chloroplast MinE ring in living mesophyll cells of Arabidopsis thaliana

Plant Signaling & Behavior
Chloroplast division is a complex process influenced by various proteins, among which bacteria-derived MinE plays a vital role in correctly placing the FtsZ-based division apparatus and initiating the division.

A Novel Z-Ring Associated Protein ZapA-Like Protein (PA5407) From Pseudomonas aeruginosa Promotes FtsZ to Form Double Filaments

Frontiers in Microbiology, 2021
Bacterial cell division is initiated by the assembly of the contraction ring (Z-ring), which consists of the self-assembled FtsZ protofilaments and dozens of other associate proteins.

Dynamic Switchable and Transient DNA Condensates Driven by Aptamer‐Ligand or Ion‐Nucleobase Bridged Complexes

Small, Volume 22, Issue 31, 2 June 2026.
Switchable or transient formation and dissociation of the phase‐separated DNA microdroplets generated by metal ions or aptamer‐ligand complexes crosslinking Y‐shaped DNA frameworks and dynamically separated by counter ligands eliminating the bridging metal ions or biocatalysts degrading the aptamer‐ligand complexes, are introduced.

Complete identity and expression of StfZ, the cis-antisense RNA to the mRNA of the cell division gene ftsZ, in Escherichia coli

Frontiers in Microbiology, 2022
Bacteria regulate FtsZ protein levels through transcriptional and translational mechanisms for proper cell division. A cis-antisense RNA, StfZ, produced from the ftsA-ftsZ intergenic region, was proposed to regulate FtsZ level in Escherichia coli ...

The Flavonoids Daidzein and Genistein Induce Wall‐Deficient Cell Formation in Streptomyces coelicolor Under Hyperosmotic Stress

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Plant‐derived isoflavones (daidzein and genistein) function as chemical signals that induce stress‐dependent formation of wall‐deficient cells (S‐cells) in Streptomyces coelicolor. ABSTRACT Streptomycetes exhibit a complex multicellular life cycle, including programmed cell death and hyphal differentiation, and can generate extracellular vesicles and ...

Engineering Pseudomonas protegens as a Targeted Antifungal‐Effector Delivery Chassis via Heterologous Type III Secretion System Reconstitution

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
A heterologous T3SS turns Pseudomonas protegens Pf‐5 into a programmable molecular syringe that delivers Bg9562 into Fusarium hyphae, suppresses fungal pathogens, enhances rhizosphere colonization and protects tomato plants from wilt. This modular platform offers a transferable strategy for next‐generation fungal biocontrol.

Polymerization and Bundling Kinetics of FtsZ Filaments [PDF]

Biophysical Journal, 2008
FtsZ is a tubulin homolog essential for prokaryotic cell division. In living bacteria, FtsZ forms a ringlike structure (Z-ring) at the cell midpoint. Cell division coincides with a gradual contraction of the Z-ring, although the detailed molecular structure of the Z-ring is unknown.

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

Molecular Microbiology, Volume 125, Issue 6, Page 506-545, June 2026.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

FtsZ ring formation in fts mutants [PDF]

Journal of Bacteriology, 1996
The formation of FtsZ rings (Z rings) in various fts mutants was examined by immunoelectron microscopy and immunofluorescence. In two temperature-sensitive ftsZ mutants which form filaments with smooth morphology, the Z ring was unable to form. In ftsA, ftsI, and ftsQ mutants, which form filaments with an indented morphology, Z rings formed but their ...

Assembly Dynamics of Mycobacterium tuberculosis FtsZ [PDF]

Journal of Biological Chemistry, 2007
We have investigated the assembly of FtsZ from Mycobacterium tuberculosis (MtbFtsZ). Electron microscopy confirmed the previous observation that MtbFtsZ assembled into long, two-stranded filaments at pH 6.5. However, we found that assembly at pH 7.2 or 7.7 produced predominantly short, one-stranded protofilaments, similar to those of Escherichia coli ...
