A phylogenomic approach to reconstruct interrelationships of main clupeocephalan lineages with a critical discussion of morphological apomorphies.

ABSTRACT:

Background

Previous molecular studies on the phylogeny and classification of clupeocephalan fishes revealed numerous new taxonomic entities. For re-analysing these taxa, we perform target gene capturing and subsequent next generation sequencing of putative ortholog exons of major clupeocephalan lineages. Sequence information for the RNA bait design was derived from publicly available genomes of bony fishes. Newly acquired sequence data comprising > 800 exon sequences was subsequently used for phylogenetic reconstructions.

Results

Our results support monophyletic Otomorpha comprising Alepocephaliformes. Within Ostariophysi, Gonorynchiformes are sister to a clade comprising Cypriniformes, Characiformes, Siluriformes and Gymnotiformes, where the interrelationships of Characifor
