In a study published April 25 in Science Advances, researchers describe how components of a bacterial flagellum’s export ring are assembled. The export ring forms at the base of the flagellum and anchors the subsequent formation of the flagellum’s other components. The researchers observed this construction in real time using high-speed atomic force microscopy.
