IFT analysis in C. elegans K04F10.2( tm1830 ) mutants. a Intraflagellar transport rates in wild-type and K04F10.2(tm1830) mutant worms. Shown are the anterograde and retrograde velocities (μm.s-1/standard deviation (SD)) of GFP-tagged IFT proteins along amphid and phasmid channel cilia (combined; top rows), or phasmid cilia only (bottom rows). t-test pairwise comparison with wild-type controls, n number of particles, N measured number of amphids and phasmids. OSM-3 is the worm orthologue of KIF17; CHE-11 is the worm orthologue of IFT140; OSM-6 is the worm orthologue of IFT52. b Representative fluorescence images of phasmid cilia showing normal IFT protein localisations and distributions in tm1830 mutants. ds distal segment, ms middle segment, bb basal body region, den dendrite. All images are similarly scaled and orientated (arrow denotes basal body). Scale bar, 3 μm. c Representative kymographs (time (t) over distance (d) plots) used to generate IFT rate measurements. For each kymograph, the horizontal axis (distance) is 5 μm and the vertical axis (time) is 25 seconds. d Distribution plots of IFT protein velocities. (JPG 1951 kb)
