Spatiotemporal regulation of peritrichous flagellation in Bacillus subtilis (P11)

The proper spatiotemporal regulation of flagella is critical for the environmental success of bac-teria. Flagella are organelles of locomotion and allow bacteria to move in accordance with chemical gradients. It has long been established that place and number of flagella (flagellation pattern) vary among the species. The most common patterns are characterized by the monotrichious (1 flagellum at 1 pole), amphitrichous (1 flagellum at each of both poles), lophotrichous (multiple flagella at 1 pole) and peritrichous (multiple flagella at the lateral sides, but not the poles) distribution of flagella. The molecular mechanisms that establish these flagellation patterns during each cycle of cell division are far from being understood. For all these different flagellation patterns, there are two proteins, FlhF and FlhG, which can be essential. This not only raises the question how the FlhF/G pair establish a flagellation pattern in a given species, but also how they can be involved in generating different ones.
