B-tubules are partially depolymerized in fap45fap52. a, b A typical tomogram of a fap45fap52 axoneme in cross-sectional (a) and longitudinal view (b). A dashed line in (a) indicates the slicing plane of (b). Arrowheads in (b) show break points in the B-tubules. c Typical thin section TEM images of fap45fap52 axonemes. Broken B-tubules were observed in 33.8% of the DMTs (n = 552). The 9+2 structure was disorganized and the axonemes were frayed in regions containing broken B-tubules. Scale bar = 100 nm
