PRG-1 suppresses a heritable form of stress that triggers adult germ cell remodeling and drives a form of arrest. Delayed fertility pathway (left) is prg-1 mutants that spontaneously reverse from loss of fertility to fertile state. Reproductive diapause pathway (right) is prg-1 mutants that remain sterile throughout adulthood and only return to fertility when given an undetermined stimulus. Blue represents germ cells. Brown represents embryos.
