Genomic and domain organization of the putative Bt-R1-like cadherin of R. dominica. (A) Schematic representation of organization of the RdCad1 cadherin gene. Thin, horizontal blue line below the black solid scale indicates the genomic sequence, with the individual exons shown as blue triangles. (B) Schematic representation of the exons (blue rectangles) and their encoded RdCad1 functional domains EC1–12, MPED, TM, and CYT (lower). The above black, solid lines correspond to the transcript coding region and the scale, respectively. The first 5’-UTR (−1) and the last 3’ (29) exons are depicted in grey, as their untranslated sequence regions were not experimentally confirmed.
