Fig. 3. lim-6 and ceh-14 coordinately affect expression of postembryonically expressed zig genes in the PVT neuron. Individuals with a chromosomally integrated zig::gfp reporter (see Materials and Methods) were crossed into the indicated null mutant backgrounds. Animals were scored at mixed stages. The modest effect of lim-6 on zig-2, zig-3 and zig-4::gfp expression (<30% off) is only manifested after the L3 stage: expression is correctly initiated but fails to be maintained. n=45-500, depending on genotype.
