Figure 3. Specificity of mys-1, ssl-1, and htz-1 Synergy with pha-4(ts) .

The indicated worm strains were fed dsRNA for GFP (negative control) or mys-1, ssl-1, or htz-1 at 20 °C (or 24 °C for WT and pha-4(ts)). Lethal embryos (black bars) or lethal L1 progeny (grey bars) were scored for each strain. Effectiveness of RNAi feeding was manifest through viable, but sterile, progeny for mys-1 and ssl-1 [14], as well as repeated enhancement of L1 lethality for pha-4(ts). n =1 00 worms/plate, three plates per column. Error bars indicate the standard deviation.
