ExTrack characterizes transition kinetics and diffusion in noisy single-particle tracks

ExTrack analyzes noisy single-particle tracks to characterize transition kinetics and diffusion by using probabilistic modeling of spatio-temporal data.

Cell-envelope synthesis is required for surface-to-mass coupling, which determines dry-mass density in Bacillus subtilis

The paper shows that surface-to-mass coupling determines dry-mass density in Bacillus subtilis by linking envelope synthesis to volume regulation.

Bacteria control cell volume by coupling cell-surface expansion to dry-mass growth

This study shows bacteria control cell volume by expanding their surface area in proportion to biomass growth, challenging the idea that cell-wall synthesis directly controls envelope expansion.

Cell-wall synthases contribute to bacterial cell-envelope integrity by actively repairing defects

The paper shows class-A penicillin-binding proteins (aPBPs), specifically PBP1b, repair cell-wall defects in E. coli to maintain integrity, independent of the Rod complex.

Transpeptidase PBP2 governs initial localization and activity of major cell-wall synthesis machinery in Escherichia coli

This study shows PBP2 initiates Rod complexes in E. coli by binding cell wall, not MreB or curvature, and limits Rod complex activity.

Cell Diameter in Bacillus subtilis is Determined by the Opposing Actions of Two Distinct Cell Wall Synthetic Systems

The paper investigates how two cell wall synthesis systems in Bacillus subtilis determine cell diameter through their opposing effects on growth and width.
