Fig. 3. GFP:MEX-5 and PIE-1:GFP dynamics in wild-type embryos (Movies 5 and 6). (A)
Pronuclear formation. (B-D) Pronuclear migration. (D) Pseudocleavage. (F)
Pronuclear meeting. (G) Mitosis. (H) Two-cell stage. Note that PIE-1:GFP
accumulates in the male pronucleus during pronuclear migration, on the
posterior centrosome during mitosis, and in the P1 nucleus in the two-cell
stage. PIE-1:GFP and GFP:MEX-5 also accumulate on the cytoplasmic P granules
(best seen in the movies).
