Plasmid partitioning driven by collective migration of ParA between nucleoid lobes

This study investigates the dynamics of ParA and its role in plasmid partitioning through collective migration between nucleoid lobes, revealing a new mechanism for plasmid segregation.

Mid-cell migration of the chromosomal terminus is coupled to origin segregation in Escherichia coli

The paper quantifies terminus migration in E. coli and identifies its coupling with origin segregation during chromosome segregation.

Star Track: Inferred counting and tracking of replicating DNA loci

The paper introduces [*]Track, a method for accurately tracking replicating DNA loci and predicting copy numbers and replication timing despite imaging noise.

Partition complex structure can arise from sliding and bridging of ParB dimers

This study uses simulations to show how ParB sliding and bridging explain partition complex formation and predict its structure.

DNA bridging explains sub-diffusive movement of chromosomal loci in bacteria

The paper shows DNA bridging by NAPs explains sub-diffusive dynamics and rare rapid movements of chromosomal loci in bacteria, with a predicted lower bound on bridge lifetime.

High-throughput imaging and quantitative analysis uncovers the nature of plasmid positioning by ParABS

This study uses high-throughput imaging and modeling to show that ParABS systems actively position plasmids with spring-like dynamics and operate near an oscillatory instability threshold.

Pal stabilises the bacterial outer membrane during constriction by a mobilisation-and-capture mechanism

The paper shows the Tol system in E. coli actively mobilizes and captures Pal to coordinate outer membrane constriction with cell division.

A gated relaxation oscillator controls morphogenetic movements in bacteria

The paper identifies a gated relaxation oscillator mechanism in Myxococcus xanthus that controls polarity reversals through FrzX and RomR, enabling tunable motility responses.

Self-Organisation And Positioning Of Bacterial Protein Clusters

The paper presents a model for self-organization and positioning of dynamic bacterial protein clusters using a phase-locked Turing pattern, explaining regular positioning of SMC complexes on the nucleoid.
