Sequence features justifying Chromosome Length Polymorphism (CLP) for two chromosome III homologues in E. cuniculi GB-M1. CDSs are represented by boxes with arrows indicating transcription direction and are ordered from telomere (left) to chromosome core (right). Grey colour is applied to the members of three multigenic families: interB, interC or interD. Name and/or Uniprot accession number are given for CDSs characterized by the genome project. The telomere-associated distal parts of the two extremities are identical up to R06 recombination site. The region of homology between the two extremities starts again just upstream of EXT10. In between, the EXT4-1-EXT2-2 organisation is 4.5 kbp longer than EXT3-2. Vertical bars show recombination sites. Their width covers the region where they are expected to be located. R01 is the only site that is precisely mapped in this region. The IIIβ1 and IIIβ2 EXT10 copies are differing by the number of copies of a CATCA microsatellite extending 3’ of NewECU03 at ~ 50 bp of R09. Very few mismatches are observed between EXT2-2 and EXT3-2 over ~ 1000 bp at the left-hand part of R09. The IIIβ2 sequence is strictly identical to VIβ end up to R09 but significant homologies persist downstream of R09 up to the middle of the NewECU03 gene. Both EXT2-2 and EXT3-2 display a G indel in a polyG repeat restoring a complete interC CDS (interC1 and interC2 genes are divergent in 5’)
