"In wild-type hermaphrodites, the somatic gonadal tissues differentiate during the L4 stage. Thus,
lim-7::GFP is expressed in the hermaphrodite gonadal sheath during L4 and is maintained throughout adulthood (Hall et al., 1999) (Fig. 5A). In
gon-4 mutants,
lim-7::GFP is expressed in a small number of cells at the same time during L4 and throughout adulthood (n=50 worms) (Fig. 5B)."
