Flagella basal body

Fig. S-36 Representations of ccntrioles. basal bodies and axonemes within a cilium. la) Ccntriole/basal body showing the nine sets of triplet microtubules, (h) Cross-section of a cilium/flagellum showing the 9 + 2" array of microtubules and accessory proteins of the axoneme. (c) View of a cell indicating the organizing role of ccntrioles and basal bodies.

Fig. 3. Electron micrograph (LS) of basal body and emergent flagellum. X 117,800.

Fig. 2. Diagrammatic representation of basal body (bb), transitional region (fr), and emergent flagellum (/) in LS and TS.

The A and B subfibers of the basal body subsequently extend to form the outer 9 doublets of the flagellum. The transitional region of the flagellum is formed before the (9-f-2) axoneme proper. 

Class G. Mutants with abnormal flagella number. In one mutant only about 10% have 2 flagella, just under 50% have a single flagellum and the remainder are nonflagellate. Basal bodies of this strain appear structurally normal.
