Fig. 8

Duplication and deletion of arrestin paralogs in lobe-finned fish. ARRB2 could not be detected in the genomes and transcriptomes of birds (see Additional file 1: Table S1 for other 41 investigated bird species). Additional omics-data was investigated for sauropsids. The gene loss/duplication pattern was simplified for the monophyletic groups highlighted in light grey (see Additional file 1: Appendix 4). See caption of Fig. 3/6 for description of symbols. The exclamation mark (!) indicates the number of stop codons contained in the exon annotation, while plus (+) indicates that gene (parts) are encoded within the respective genome, but were not annotated in detail. Note that the order of the ARRB2.2 and ARRB1.2 losses is arbitrary. The phylogenetic tree was created using Treegraph 2.0.54 [114]. PG - pseudogene; PRG - pseudo-retrogene
