Increased flagellation enhances bacterial migration against and across flow

This study shows that increasing flagellation in E. coli improves its ability to swim against and across fluid flow by enhancing propulsion and directional control.

Stator pool size shapes the mechanosensitivity of the bacterial flagellar motor

The paper uses a statistical mechanics model to show that stator pool size determines the load range over which the bacterial flagellar motor is mechanosensitive.

Osmotic stress triggers fast and reversible PMF collapse in Escherichia coli

The paper measures PMF dynamics in E. coli under hyperosmotic stress using the flagellar motor as a voltmeter, finding rapid and reversible PMF loss.

Long-range coupling regulates stator dynamics in the bacterial flagellar motor

This study shows that long-range allosteric interactions in MotB regulate stator dynamics and torque in the bacterial flagellar motor, affecting swimming behavior in E. coli.
