Figure 4. Expression of zag-1::gfp in wild-type and ceh-28 mutants.

Fluorescence (left) and DIC (right) micrographs of zag-1::gfp wgIs83 in wild-type (A) and. ceh-28(cu11) mutant (B) adults. M4 is indicated (arrowhead) in (A). The anterior pharyngeal lumen is stuffed with bacteria in (B), and this results in non-specific autofluorescence.
