WormMine: ExpressionPattern Expr14526

• Pattern: The expression of the functional egl-9::gfp reporter could be observed in the VPCs and their descendants throughout vulval development. At the onset of vulval induction in mid L2 larvae, the egl-9::gfp reporter was expressed in all VPCs, although expression levels were slightly higher in the three proximal VPCs P5-7.p than the three distal VPCs P3.p, P4.p, and P8.p. In late-L2/early-L3 stage animals, EGL-9::GFP expression remained prominent in the proximal VPCs but decreased in the distal VPCs as they started dividing. After completion of the first round of VPC divisions in mid-L3 larvae, EGL-9::GFP expression faded in the 1° P6.p descendants and increased in the 2° P5.p and P7.p descendants.
