Results of RNAi by soaking. (A) All ovary-enriched genes tested in this study. (B) Genes not previously tested by RNAi. (C) Genes that displayed only post-embryonic defects in previous RNAi studies. (D) Genes previously tested by RNAi for which no phenotype has been reported. MS, maternal sterile, three broods with ≤10 progeny; EL, embryonic lethal, 80%-100% embryonic lethality; HPEL, high-penetrance embryonic lethality, 50%-80%; LPEL, low-penetrance embryonic lethality, 20%-50%; VLL, very low lethality, 5%-20%; LCL, low-confidence lethality; NELD, no embryonic lethality detected.
