Figure 3

Detailed representation of five genomic zones identified in O. latipes IGH locus. It shows the D, JH segments, constant (C) and (TM) exons as rectangles or arrowheads. The demarcation of exons was performed by using the computer software (FGNESH and Augustus) and alignment was done with ESTs. The exons and sequences in red were identified or corrected based on the analysis of ESTs and the next generation sequence data (SRA026397 and DRA000220). In zone 5/x the question mark sign (?) indicates the presence of a gap and the possibility that zone x is integrated in zone 5. Zone x presents Cμ sequences belonging to scaffolds 3172 and 1447 and they are not assigned to any chromosome (For more information see Additional file 2).
