Presence of DAF-19 activates expression of novel target genes in certain ciliated sensory neurons. Expression patterns of transcriptional fusions of daf-19 target gene promoters with the GFP gene in isogenic daf-12(sa204) and daf-19(m86); daf-12(sa204) adult hermaphrodites (N = 30 worms/strain analyzed). Views are lateral with dorsal at the top and anterior to the left, except strains expressing eppl-1::gfp. Neurons in which daf-19-dependent expression was found are identified. Cell bodies in which gene expression is absent in daf-19(m86) mutants are indicated by dotted circles. Bar, 10 μm.
