This study mainly investigates the expression of the Ammecr gene family during embryonic development in medaka and zebrafish and its systematic evolution. Through gene sequence analysis, it was found that the Ammecr gene family is related to the metabolic pathway of glycine and serine synthesis and their expression gradually increases during embryonic development. At the same time, analysis of the evolutionary relationship of the Ammecr gene family in medaka and zebrafish found that they have relatively high homology with the Ammecr gene family in whales and mammals, and may have undergone duplication and transposition events during evolution. The results of this study are of great significance for further exploring the function and evolutionary mechanism of the Ammecr gene family.Keywords: Ammecr gene family; medaka; zebrafish; embryonic development; systematic evolution; expression
