Functions of maternal mRNA as a cytoplasmic factor responsible for pole cell formation in Drosophila embryos.


Injection of mRNA extracted from Drosophila cleavage embryos or mature oocytes restored pole cell-forming ability to embryos that had been deprived of this ability by uv irradiation. However, mRNA extracted from blastoderms did not show the restoration activity. Pole cells thus formed in uv-irradiated embryos bear similarities to normal pole cells both in their morphology and their ability to migrate to the gonadal rudiments. But this mRNA does not appear to be capable of rescuing uv-induced sterility, or inducing pole cells in the anterior polar region.
