Genomic Insights Into Carnivorous Fish in the Characiformes. [PDF]

open access: yesEcol Evol
This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...
