Phylogenomic microsynteny analysis of animal FIB proteins.
a) Phylogenetic tree of the total 319 FIB proteins detected across 257 inspected genomes (195 Vertebrata and 62 Invertebrata). Color-coded gene names are on the tree by taxonomic affiliation, as indicated on the left. The color of the first inner strips is by major taxonomic groups: Invertebrata (black) and Vertebrata (yellow). The second inner strips are colored by relevant taxonomic group, as indicated on the left. Internal pairwise connections between tree leaves represent pairwise synteny relationships and are colored by the four detected microsynteny clusters in Vertebrata, as shown in Fig 2B and S13 Fig. Internal pairwise connections in gray represent minor microsynteny relationships not included in any community. Black dots on the tip of the leaves represent genes belonging to the only orthogroup detected in animals. b) Representation of microsynteny blocks of FIB and FIB-like genes. The Xenarthra species D. novemcinctus is absent in the FIB syntenic block. In the FIB-like syntenic block, only sequences from eutherian mammals are present. Colored blocks represent syntenic genes.
