CNG channel subunits are expressed in subsets of ciliated sensory neurons. (A) Expression of cng fusion genes in the heads of adult hermaphrodites. Sensory neuron cell bodies are indicated by an arrow. Extent of cng sequences present in the fusion constructs: cng-1, 1.2 kb upstream regulatory sequences of F14H8.6a; cng-2, 2.1 kb upstream regulatory and first ten exons of Y76B12C.1; cng-3, 764 bp upstream regulatory sequences of F38E11.12; cng-4, 772 bp upstream regulatory sequences of C23H5.7. Note that the expression pattern of cng-1 reported here differs from a previous report (Cho et al., 2005) probably due to differences in the extent of regulatory sequences used to drive gfp expression. cng-4p::gfp expression (shown here as a maximum projection confocal image) was too weak to reliably identify all expressing cells. Anterior is left. Scale bars: 20 µm. (B) Summary of CNG channel subunits known to be expressed in the indicated sensory neurons in the head amphid organ. Four sensory neurons (AWA, ADF, ASH and ADL) do not express any CNG channel subunits.
