A short gcy-33 promoter fragment is expressed in the BAG sensory neurons ( Yu et al., 1997 ), here was observed that an extended gcy-33::GFP reporter gene fusion was expressed in BAG, URX, AQR, and PQR neurons.

To our surprise, we also found that the egl-1 reporter was expressed in adult animals in a very small subset of neurons, and in one pair especially strongly in all individuals. This expression persisted throughout the entire life of the worm. We used cell-specific reporters and morphological characterization to identify the neurons most brightly expressing the reporter as the bilaterally symmetric neuron pair URX (YU et al. 1997). By examining eggs, we found that egl-1 reporter expression was detectable in URX by at least the 3-fold stage, albeit at extremely faint levels compared to later expression. In addition to URX, we also found that AQR, PQR and one of the AWCon/off neuron pair expressed the reporter less often. Of these neurons, the expression in the URX neuron pair was the most consistent and robust.
