title: Isolation and characterization of a region of the Drosophila genome which contains a cluster of differentially expressed maternal genes (yema gene region).
abstract: We have characterized a genomic clone of Drosophila melanogaster which codes for four transcripts that are synthesized during oogenesis, remain abundant in the preblastoderm embryo, and then vanish during gastrulation. One of the transcripts varies in concentration along the anterior-posterior axis of the oocyte. This cluster of maternally acting genes (yema) maps to 98 F3-10 on chromosome arm 3 R.
