Figure S5. Pral-1::gfp is Dynamically Expressed during Vulval Development, related to Figure 6 (A-C) The post-inductive expression pattern of the transcriptional fusion Pral-1::gfp during vulval development. The earlier expression pattern is shown in main text. (A) Pn.px stage. (B) Pn.pxx stage. As previously observed, we found two rather than four nuclei in the 3 lineages, because the 3 VPC divides once and fuses with the hypodermis (3 is a non-vulval fate) (Sulston and Horvitz, 1977). By DIC four nuclei were present in each of the vulval lineages where GFP was absent (data not shown). (C) Late L4 (morphogenesis). Expression was clearly restricted to a sizable set of 2 lineages, but we did not determine whether expression is in all 2 cells. (D) Post-inductive expression pattern schematic and details.
