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.
This construct was expressed faintly in QL and QR, more strongly in the neighboring epidermal cells (dorsal hyp7 cells, ventral P cells and lateral V cells), and in dorsal and ventral body muscle cells.
Staining was observed in all larval and adult stages, localizing to the nuclei of the hypodermal cells, specifically the head (hyp3, hyp4, hyp6, and hyp7) and seam/body (hyp7, H, V, and P) hypodermal cells.
