General motifs of flagella number control and cellular counting — •Richard Swiderski, Florian Raßhofer, and Erwin Frey — LMU, Munich, Germany

Monopolarly flagellated bacteria tightly control the flagellum assembly in order to construct only a single flagellum. Building upon models of the highly conserved C-ring assembly machinery, we present a theoretical study which identifies key motifs for number control in stochastic reaction networks. These findings not only help us to better understand the counting mechanism behind flagellum assembly, but can also be applied to more general processes which require the control of particle numbers. In the future this might be applied in medical treatments which rely on precise dosage on a cellular level.
