| Pattern | The short ilys-3 promoter drove GFP expression mainly in the pharynx grinder muscles pm7, the isthmus marginal cell mc2 and muscle cell pm5. In addition, all intestinal cells exhibited ilys-3 promoter activity, with some variability. Intestinal expression of ilys-3 appeared to be temporally regulated. GFP was first detected in intestine of L1 hatchlings but declined at the L2 transition. By the L4 stage, the intestinal GFP signal became stronger and continued through adulthood. The intensity of GFP was very high in aging adult worms that were no longer self-fertile. Whereas the intestinal expression of ilys-3 changed during larval growth and adult life, the pharyngeal GFP reporter expression remained constant in larval and adult stages. Weak epidermal promoter activity was also detected. The long ilys-3 promoter revealed additional GFP expression in the six scavenger coelomocyte cells, but at a significantly lower level in other tissues. | |
