Schematic representation of the genomic region corresponding to CycJ, armi, and the neighboring genes on chromosome 3L. The region shown corresponds to estimated cytological band 63E1. Black boxes represent coding regions and open boxes represent 5' and 3' untranslated regions. armi and CycJ are transcribed left to right while all other genes shown are transcribed right to left (arrows). FRT-bearing transposon insertions RBe00161 and XPd07385 (shown by triangles) were used to delete the intervening genomic region. The deleted genomic region is represented as Df(3L)armi-J. Rescue experiments were conducted by using independent transgenes, P{armi}, P{CycJ}, and P{CG14971} that were generated using the indicated genomic regions (shaded boxes). Rescue experiments also used a second CycJ genomic transgene, P{HZ14CycJ}, that introduced stop codons (# stop) in the armi coding region eliminating armi coding potential. Regions missing in the deficiency chromosomes Df(3L)Exel6094 and Df(3L)Exel6095 are indicated by dashed lines and extend beyond the region shown (arrowheads).
