Fig. 1. Map of the ecd locus. The interval of ecd is delimited by the right breakpoints of deletions Df(3L)Aprt201 and Df(3L)R+R2 within the cytological region 62D5-D7 (top). Ten predicted genes (BDGP) located in this interval are shown. The filled boxes represent coding regions and the lines between them denote introns, arrows indicate the orientation of each gene. Five genomic fragments used for the preparation of rescue constructs are indicated by the black lines. CG5714 (underlined), present in the rescuing fragments E5 and S4, is the ecd gene.
