Conserved synteny in the genomes of teleost fish aids in the rapid development of genomic tools to query fundamental biological and evolutionary questions
As two species diverge, much of their genomes begin to differentiate. In many lineages, however, the genomic structure remains remarkably intact, with orthologous gene content maintained across millions of years and significant changes to their biological characteristics. The maintenance of gene con...

As two species diverge, much of their genomes begin to differentiate. In many lineages, however, the genomic structure remains remarkably intact, with orthologous gene content maintained across millions of years and significant changes to their biological characteristics. The maintenance of gene content is defined as conserved synteny while the preservation of gene order is defined as conserved linkage; the conservation of both can be incredibly informative when interrogating and comparing two genomes. In non-model organisms, linkage conservation to a well-developed model allows informed, cost-effective and rapid answers to fundamental biological questions without generation of equivalent resources. With the development of new model organisms, we can begin to discuss more fundamental evolutionary concepts, such as the maintenance of chromosomal gene content across larger evolutionary time-scales, or the reorganization that occurs in chromosomes following major genomic events such as whole-genome duplications. In this work, I utilized the rapid development of primary genomic resources in the non-model teleost sablefish (Anoplopoma fimbria) to demonstrate that conserved linkage to a model genomic reference can identify the gene most likely responsible for genetic sex-control. I then assembled the first genome for a non-duplicated member of the teleost lineage Protacanthopterygii, the northern pike (Esox lucius), and demonstrated the conservation of synteny between three major lineages of teleosts, the Protacanthopterygii, the Acanthopterygii and the Ostariophysi.
