Regulation of flagella

Flagellar gene networks are fascinating, owing to their complexity — they usually coordinate the expression of more than 40 genes — and particular wiring that elicits temporal expression coupled to organelle morphogenesis. Moreover, many of the lessons learned from flagellar regulation are generally applicable to type III secretion systems. Our understanding of flagellar networks is rapidly expanding to include diverse organisms, as well as deepening to enable the development of predictive wiring diagrams. Numerous regulators control the regulation of flagella, and one of the next challenges in the field is to integrate flagellar gene control into master blueprints of global gene expression.
