📢Our MD simulation is out in Biophysical Journal! The nonequilibrium polysome dynamics expands bacterial nucleoids and helps separate daughter chromosomes. Results agree with our previous experiments and extend our earlier model. authors.elsevier.com/a/1mBGt_9FM7... #Microbiology #Biophysics

Snapshot of a model showing two chromosomes (red spheres on the left and yellow ones on the right) before they are fully separated. Kymographs (bottom row) show the density of two daughter chromosomes (left) and ribosomes (right) as a function of time in the presence of nonequilibrium reactions of ribosomes. Blue corresponds to low and red to high density. As time progresses, the two chromosomes separate, but only when the reactions are present. The snapshot above corresponds to time t = 0 in the kymographs.

Our latest work is out in PNAS!🎉 We show that nonequilibrium polysome dynamics help drive sister chromosomes apart. The closing division septum also contributes via steric interactions.👇 www.pnas.org/doi/10.1073/... #MicroSky #Microbiology #Biophysics #CellBiology

Diagram of an E. coli cell showing polysomes pushing sister chromosomes apart. Bottom heatmaps show cell-cycle-dependent
changes in DNA and ribosome density distributions, and constriction formation. The top right corner shows normalized mid cell amounts from these heatmaps (integrated between the dashed horizontal lines).

Crazy stuff in PNAS dental plaque bacterium 𝘊𝘰𝘳𝘺𝘯𝘦𝘣𝘢𝘤𝘵𝘦𝘳𝘪𝘶𝘮 𝘮𝘢𝘵𝘳𝘶𝘤𝘩𝘰𝘵𝘪𝘪 can divide into an unprecedented 14 daughter cells at once—then each daughter cell starts growing immediately in a rare process called multiple fission, achieving 0.5 mm per day of expansion www.snexplores.org/article/bact...

These mouth bacteria use a new type of cell division to make 14 cells at once

The newfound strategy seen in C. matruchotii might help oral bacteria recover lost territory after each eviction by toothbrushing.
