Figure 1

Genomic structure of the fem (Af-femF, female splice variant) and csd (Af-csd) genes in Apis florea, domain diagram of Csd and Fem and conceptual translations spanning the hypervariable region (HVR) of four honey bee species. (a) Coding exons are marked in black; untranslated regions are in white. Translational start and stop sites are indicated. In the csd gene, the position of the HVR is marked (exon 7). * indicates the position of the predicted coiled-coil motif in A. mellifera, A. cerana, A. dorsata, but missing in A. florea (see Figure 2b). In A. florea, a coiled-coil motif is predicted in exon 2 (marked as CC). (b) Protein domains of Csd and Fem (above): arginine-serine domains are indicated in red, the HVR in green and the proline-rich region in blue. Below: conceptual alignment of deduced amino acids residues of the HVR in csd and the corresponding region of fem. Am, A. mellifera; Ad, A. dorsata; Ac, A. cerana; Af, A. florea.
