Fig. 5. The hlh-2 and nhr genes are involved in vulval induction
and the expression of lin-3::gfp in the AC. (A-D) Defective
lin-3::gfp expression in the AC was caused by soaking animals in the
dsRNA solution against hlh-2. Transgenic animals that contain
lin-3::gfp extrachromosomal arrays were soaked in the control dsRNA
solution (RNA synthesized from blank vectors) and in the dsRNA solution
against hlh-2. (B,D) GFP expression in the AC was examined in the
animals that express gfp in pharynx at the early L4 stage. (E-G)
Defects in vulval induction and vulval-uterine connection in animals treated
with dsRNA against hlh-2. (E) Wild-type vulvae with control RNAi. (F)
Defective vulval induction after hlh-2 RNAi. (G) Defective
vulval-uterine connection after hlh-2 RNAi. (H-J) Defects in vulval
induction and vulval-uterine connection in animals treated with dsRNA against
nhr-25. (H) Defective vulval induction after nhr-25 RNAi.
(I,J) Defective vulval-uterine connection after nhr-25 RNAi.
