The sox family is assumed to be responsible for a number of developmental systems. Genome sequencing technology makes it possible to scan sox genes and conduct characteristic analyses of different species. In fish, full characterisation of sox genes at the genome‐wide level has been reported for pufferfish Takifugu rubripes , medaka Oryzias latipes , tilapia Oreochromis niloticus and channel catfish Ictalurus punctatus .
