atgl-1p::GFP fluorescence is bright in the intestine, consistent with a previous report (Lee et al, 2014). We also found weak expression in neurons in the nerve ring, ventral nerve cord, and tail.
The C+C enhancer (pOK17.21) activates frequent expression in all pharyngeal muscles. the C+C enhancer also activates expression in non-muscle cells in the pharynx. Expression induced by the C+C enhancer was observed in all pharyngeal cell types including gland cells, neurons and marginal cells as well as muscles. These results define C as an organ-specific subelement.
