Pole cell transplantations were used to determine the tissue specificity of maternal effects in Drosophila. The deep orange maternal effect is shown to be germ line autonomous. A cytoplasmic injection assay was used to determine when the dor+ substance could be detected in the developing oocyte. The dor+ substance is present during the early stages of vitellogenesis but could not be detected in the yolk of the embryo after blastoderm cellularization.
