(A) Diagram of the TLDc-only Mtd transcripts mtd-RH and mtd-RC, the LysM-only transcript mtd-RD, and a representative LysM/TLDc transcript mtd-RB encoded in the mtd locus. Small rectangles represent exons. The exons containing the conserved LysM and TLDc domains are labeled and filled in white and black, respectively. Triangles indicate the sites of transposon insertions studied here. The box below contains the locations of the amplicons generated in qRT-PCR experiments shown in B–E and the corresponding transcript detected. (B–E) Relative transcript levels of mtd-RC, mtd-RH, mtd-RD and all long transcripts (TLDc+LysM) in the mtdEY04695 mutant as compared with yw flies (WT). *** indicates p < 0.001.
