..., we show that loss of lin-28 , a central heterochronic regulator of hypodermal development, causes reduced fertility associated with abnormal somatic gonadal morphology. In particular, the abnormal spermatheca-uterine valve morphology of lin-28(lf) hermaphrodites traps embryos in the spermatheca...

...Lynn M. Clary; Peter G. Okkema Oocyte production, maturation and ovulation must be coordinated with sperm availability for successful fertilization. In C. elegans this coordination involves signals from the sperm to the oocyte and somatic gonad, which stimulate maturation and ovulation. We have...

... mutant Pro phenotype stems from defects in the time and position of the first meiotic entry during early germline development. pro-1(RNAi) produces a loss of somatic gonad structures and concomitant reduction in germline proliferation and gametogenesis. pro-1 encodes a member of a highly conserved...
