A GFP reporter under the control of 1,566 bp of
rabs-5 upstream regulatory sequence (
rabs-5p::GFP) is expressed predominantly in ciliated cells, including all dye-filling amphid and phasmid neurons, male tail ray neurons and the PQR neuron (weaker expression). No apparent differences in
rabs-5p::gfp expression were found in L1 vs. adult worms.
