Fig. 5: Specific Evolution of Regulatory Elements and Genes in the Amazon Sailfin Catfish.

A Genes and their functional enrichment nearest to specific insertions larger than 15 bp identified within conserved non-coding elements (CNEs) in the Amazon sailfin catfish within 2000 bp of these insertions. B Functional enrichment of rapidly evolving genes (REGs) and positively selected genes (PSGs) identified in the Amazon sailfin catfish. C Synteny comparison of the hoxb9 gene between the Amazon sailfin catfish and other catfish species. D Positively selected sites identified in the hoxb9 gene in the Amazon sailfin catfish.
