Asymmetry of the molecular arrangement of dynein and inter-doublet linkers in Chlamydomonas flagella. (a), (b) Common architecture seen in doublets 2–8 [defined in (g)]. (c), (d) Doublet 9. (e), (f) Doublet 1. (a), (c), (e) Density maps of averaged tomograms. Missing dyneins are shown by arrows. Scale bar = 20 nm. (b), d), (f) Models of the inner arm dynein arrangement. ODA: outer dynein arm. IDA: inner dynein arm. DRC: dynein regulatory complex. IC/LC: intermediate and light chains. S1, S2: radial spokes 1 and 2. Inner arm dyneins (a, b, c, d, e, f, g) are indicated. (g) Inter-doublet linkers are shown on a vertical section of a flagellum (green and red lines). Inner dynein arms lacking some isoforms are shown by black dotted lines. Modified from Bui et al. (2009BB3).
