Gene synteny comparisons provide evidences that multiple nanos1 gene duplications and losses occurred in vertebrates Three nanos1 paralogs and their neighbouring genes showed syntenic genomic locations through Vertebrates. In the top panel, genes in the vicinity of a first copy, named nanos1A, were mapped. The figure was not drawn to scale. Each gene was represented by a specific coloured box. The name of each scaffold or chromosome harbouring the synteny is indicated at the top for each species whereas nanos1 gene copy and protein accession numbers are detailed at the bottom. Although the structure of the chromosomal fragment was well conserved during the evolution, the nanos1A gene copy is not observed in the genome of Teleost fish as symbolized by the dotted boxes. In the bottom panel, the genomic environment of the second nanos1 gene copy, termed nanos1B, was similarly represented. This different syntenic chromosomal fragment was not found in lamprey suggesting its apparition in Gnathostomata. Both nanos1 paralogs (nanos1A and nanos1B) were detected In Chondrichthyes (dogfish and whale shark) and in Osteichthyes, respectively at the basis of Sarcopterygii (coelacanth) and of Actinopterygii (spotted gar). In contrast, nanos1B gene was not found in elephant shark, xenopus, green anole, chicken and human, suggesting its loss in these species. Teleosts showed two nanos1B gene copies carried by similar but distinct chromosomal fragments. The two nanos1 paralogs in Teleosts were re-named nanos1Ba and nanos1Bb. Note that zebrafish is an atypical fish species because its genome does not harbour the nanos1Ba gene copy as indicated by a spotted box.
