Fig. 6. aha-1 but not daf-21 is required for AHR-1 function in RMEL/R cells. (A-D) P_unc-25GFP expression in different mutants. Left and middle panels show two focal planes focused on RMED/V and RMEL neurons, respectively. Right panel shows the schematic illustration. Asterisk indicates process from RMED/V neurons; arrowheads, the ectopic processes from RMEL neurons. An aha-1 mutant has the same RMEL phenotype (arrowheads) as an ahr-1 mutant (B,C). In a daf-21 mutant, RMEL and RMER neurons are normal (D). (EH) Mutations in aha-1 but not in daf-21 suppress the effect of ectopic ahr-1 expression in juEx467. Two focal planes are shown in G and H. Arrowheads in E and F indicate the processes from RMED/V neurons, and in H indicate the ectopic process from RMEL in aha-1 mutants. Asterisk in G indicates the processes from RMED/V neurons. Scale bar: 50 µm.
