(A) Confocal fluorescent images exhibit the localization of tdTomato-tagged TRAM-1 (a PCMC marker) and MSK-2::GFP (a TZ marker) in WT and indicated mutants. TRAM-1 leaks into the cilia in all three wdr-31 triple mutants. Cilia, the periciliary membrane compartment (PCMC), and transition zone (TZ) are depicted in the fluorescent image. Scale bars: 2 μm, (B) TRAM-1 fluorescence intensities in the cilia were measured in WT and designated mutants, and the results were shown in the plot. The four asterisks (****) indicate statistically significant differences between the WT and the identified triple mutants. (C, D) The localization of NPHP-1::GFP (a transition zone protein) and FBF-1::mCherry (a transition fiber protein) was similar unaffected in wdr-31;elmd-1;rpi-2 triple mutants (D) The PLCδ1-PH::GFP (a marker for monitoring phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) in the plasma membrane) decorates the membranes of PCMC and does not enter into the cilia in WT. MKSR-2 was used to mark the transition zone. The PLCδ1-PH::GFP stays outside of the cilia in the wdr-31;elmd-1;rpi-2 triple mutants. |
