Zea mays Drought‐Overly Sensitive1/TUBA4 Is Wilty3, and Transcriptome Co‐Expression Analysis of Shoot Meristem Mutant Tissues Reveals Wilty2/TUB6:Wi3 Interactions Associated With Stem Vascular Bundle Development

Plant Direct, Volume 10, Issue 9, September 2026.
ABSTRACT Plant vasculature is essential for the transport of water, nutrients, and signaling molecules across organs, while also providing critical mechanical support for growth and development. Disruptions in vascular bundle formation can therefore lead to severe physiological and developmental defects.

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.

Chemical Optimization of Temporin A–L Peptides: From Native Isoforms to Enhanced Antimicrobial Analogs

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Temporins, among antimicrobial peptides, are short frog‐derived molecules with potent antibacterial activity. This review highlights chemical optimization strategies applied to temporins A–L, showing how sequence tuning modulates structure, stability, and selectivity, enabling improved activity against resistant pathogens.

ZipA induced bundling of FtsZ and co-polymerized with FtsZ.

, 2013
FtsZ (2 µM) was polymerized in 25 mM PIPES buffer, pH 6.8 containing 1 mM MgCl2 and 1 mM GTP at 37°C in the absence and presence of ZipA. FtsZ polymers were observed using a fluorescence microscope and a differential interference contrast microscope ...

FtsZ Polymerization Assays:Simple Protocols and Considerations [PDF]

, 2013
During bacterial cell division, the essential protein FtsZ assembles in the middle of the cell to form the so-called Z-ring. FtsZ polymerizes into long filaments in the presence of GTP in vitro, and polymerization is regulated by several accessory ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, Volume 600, Issue 15, Page 2154-2174, August 2026.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Proteolysis-Dependent Remodeling of the Tubulin Homolog FtsZ at the Division Septum in Escherichia coli. [PDF]

PLoS ONE, 2017
During bacterial cell division a dynamic protein structure called the Z-ring assembles at the septum. The major protein in the Z-ring in Escherichia coli is FtsZ, a tubulin homolog that polymerizes with GTP.

Lymphatic Drainage of Cerebrospinal Fluid Using Lymph Node Seeker 64Cu‐Labeled Gram‐Negative Bacterial Extracellular Vesicles With Positron Emission Tomography (PET)

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
ABSTRACT Cerebrospinal fluid (CSF) is drained into the systemic lymphatics via paravertebral lymph nodes. Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu‐albumin ...

FtsZ dimerization in vivo

, 1999
A hybrid assay, based on the properties of the lambda repressor, was developed to detect FtsZ dimerization in Escherichia coli in vivo. A gene fusion comprising the N-terminal end of the lambda cI repressor gene and the complete E.

Location of dual sites in E. coli FtsZ important for degradation by ClpXP; one at the C-terminus and one in the disordered linker.

PLoS ONE, 2014
ClpXP is a two-component ATP-dependent protease that unfolds and degrades proteins bearing specific recognition signals. One substrate degraded by Escherichia coli ClpXP is FtsZ, an essential cell division protein.
