Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis

Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...

Chromosome organization shapes replisome dynamics in Caulobacter crescentus

Suliana Manley, Chen Zhang, Laurent Casini

DNA replication in bacteria takes place on highly compacted chromosomes, where segregation, transcription, and repair must occur simultaneously. Within this dynamic environment, colocalization of sister replisomes has been observed in many bacterial specie ...

Bacterial colonization in realistic environments: how mechanics impact biofilm formation in the wild and during infection

Tamara Rossy

A variety of physical inputs acts onto bacteria in nature. However, these are most often ignored in the studies of their physiology. There is now increasing evidence indicating that bacteria respond to physical stimuli, including mechanical forces. Yet, qu ...

A ‘common garden’ to understand and predict effects of glacier shrinkage of microbial life in high-mountain streams

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Tyler Joe Kohler, Jade Brandani, Stylianos Fodelianakis, Paraskevi Pramateftaki

In alpine regions worldwide, climate change has induced unprecedented glacier shrinkage, and various stream ecosystems draining glacierized catchments are experiencing profound environmental changes. However, how microbial life in these streams will be aff ...

Bacteria: Driving polar growth

Neeraj Dhar

Profiling the phenotype of 200,000 mutants revealed a new cofactor that may help a group of rod-shaped bacteria elongate and grow. ...

Cellular advective-diffusion drives the emergence of bacterial surface colonization patterns and heterogeneity

Alexandre Louis André Persat, Tamara Rossy

Microorganisms navigate and divide on surfaces to form multicellular structures called biofilms, the most widespread survival strategy found in the bacterial world. One common assumption is that cellular components guide the spatial architecture and arrang ...

Bacterial cell cycle dynamics: size regulation during exponential growth and role of polyphosphate during starvation response

Aster Louis K Vanhecke

Bacteria are the most diverse and abundant kingdom of life and have adapted to survive and thrive in habitats around the globe. When provided with ample nutrients they grow and divide at staggering rates, increasing their population exponentially. Upon nut ...

Two nanomachines drive evolution in diverse Vibrio species

Noémie Matthey

Horizontal gene transfer (HGT) has a major impact on bacterial evolution, leading to acquisition or deletion of genes and gene clusters, including those encoding antibiotic resistances and virulence factors. HGT therefore contributes to pathogen emergence, ...

Constriction Rate Modulation Can Drive Cell Size Control and Homeostasis in C. crescentus

Suliana Manley, Seamus John Holden, Anna Archetti, Aster Louis K Vanhecke, Ambroise Justin Lambert, Felix Max Schaber

Rod-shaped bacteria typically grow first via sporadic and dispersed elongation along their lateral walls and then via a combination of zonal elongation and constriction at the division site to form the poles of daughter cells. Although constriction compris ...
