In the wild type background,
flp-2prom::gfp gave a clear consistent GFP signal in MCs, in UL3795 and 3 other independent transgenic strains, although expression was normally weaker than in other cells. In contrast, in the
ceh-19 mutant,
flp-2prom::gfp expression in MC was not detectable, suggesting CEH-19 is required for
flp-2 expression in MC.
