Figure 4

Increased H3K4me2 retention in Z2/ Z3 correlates with sterility. A, Embryos from the experiment in Figure 2 were assayed for PGC H3K4me2 levels by immunofluorescence. Each number represents the percentage of embryos scored positive for H3K4me2 retention out of 50 total embryos for that generation. Examples of wild-type (B) and retained (C) H3K4me2 levels in Z2/Z3. Arrowheads indicate Z2 and Z3. D, The percentage of sterile offspring in spr-5, spr-5;amx-1, nos-2(RNAi), nos-2(RNAi);spr-5 and nos-2(RNAi);spr-5;amx-1 assayed at generations 1 and 16. L4440 is the vector only RNAi control.
