Schematic representation of the lmg locus. The molecular map of the lmg locus represents the ~2.0 kb cDNA sequence available in FlyBase (A). It indicates the two ORFs (rectangles), transcription start sites (TSS1 and 2), P element insertion sites (triangle), the extension of deletion in the lmgJ023 and lmg138 alleles and the 3'-end of the monocistronic transcript identified by RACE. It also shows the relative location of RACE primers used in this work. The primer pairs used for developmental RT-PCR experiments and their relative locations are also displayed (B).
