In wild-type, OSM-9::GFP is concentrated in OLQ and phasmid cilia. In other sensory cilia in the head, the OSM-9::GFP signal is very dim. In the
che-3(
e1124) mutant, OSM-9::GFP forms large puncta within OLQ cilia or aggregates at the ciliary base. In
che-3 phasmid cilia, OSM-9::GFP concentrates in enlarged bulb-like cilia.
