Three independent lines of transformed nematodes expressing the W03G9.4::GFP transgene showed fluorescence that was entirely restricted to the intestinal cells of larval and adult stages. A common pattern in adult hermaphrodites was strong expression of GFP in the most anterior gut cells (Int 1) accompanied by less pronounced expression in the mid-gut and posterior-gut cells. The other frequently observed pattern, especially in larval stages, was equally strong expression in both the Int 1 cells and cells of the posterior region of the gut. The fluorescence was detected in the intestine from the L2 stage through to the adult, but no GFP expression was observed in embryos.
