| Subcellular_localization | The OMA-1::GFP fluorescence in the developing oocytes and one-cell embryos recapitulated the wild-type spatial and temporal patterns of OMA-1 antibody staining. The punctate staining appeared more pronounced and resembled the characteristic pattern of germline P granules. Starting with the onset of the first mitotic division, the intensity of OMA-1-GFP fluorescence rapidly decreased, and by the time the division was complete, only approximately 10% remained. Interestingly, that remaining 10% of the GFP signal in the two-cell embryo was predominantly found in the germline precursor, P1, associated with what appeared to be P granules. The GFP signal continued to decrease in two-cell embryos and again was asymmetric after the next division, with most of the remaining fluorescence segregated to P2, where it was also predominantly associated with granules. The OMA-1-GFP signal became too weak to detect in the embryo after the four-cell stage. | |||
