Longer time span to reach adulthood and reduced brood size resulting in sterility between generations F3 and F4 (PubMed:17967446). Associated embryonic lethality and additional somatic defects at elevated temperatures (PubMed:17967446). Defects in germ cells including defective sperm development and endomitotic oocytes (PubMed:17967446, PubMed:24682813). Significantly reduced H3 'Lys-4' trimethylation in both embryonic and adult germ cells in a sex-independent manner (PubMed:17967446). Increased fog-3 expression at 20 degrees Celsius (PubMed:24682813). At 20 and 25 degrees Celsius, double knockdown mutants with wdr-5.2 have increased fog-3 expression (PubMed:24682813). At 25 degrees Celsius, these mutants have increased wdr-5.2 and fog-1 expression, reduced brood size accompanied by 42% embryonic lethality with 100% of the surviving progeny being sterile (PubMed:24682813). Surviving progeny display enhanced defects in the spermatogenesis to oogenesis transition compared to the single wdr-5.1 knockout with 88% of the gonads only containing sperm (PubMed:24682813). The remaining germ cells in the gonads switch to oogenesis, but the oocytes display either an endoreplication or endomitotic phenotype (PubMed:24682813). Germ cells also have increased expression of the sex determining factor tra-1 in the cytoplasm and as a result there is reduced binding of tra-1 to the fog-3 promoter (PubMed:24682813). RNAi-mediated knockdown leads to an enrichment of mono-unsaturated fatty acids (PubMed:28379943). {ECO:0000269|PubMed:17967446, ECO:0000269|PubMed:24682813, ECO:0000269|PubMed:28379943}. |
