Molecular map of the gek locus. 0
represents the 5′ end of a full-length cDNA. The transcription unit is
shown below, with the introns in dotted lines and the ORF in bold. The
P-element insertion site is indicated. Brackets mark the extent of
deletions in the three gek alleles (D23, D31, and D134)
used for the phenotypic analysis. The hatched bar represents the
construct used to rescue the oogenesis phenotypes. Restriction enzymes:
R, EcoRI; H, HindIII; S,
SalI; and X, XbaI.
