The aim of this study is to explore the expression characteristics of the egg-type aromatase gene of the red spotted grouper and its promoter function, and to provide scientific basis for the development of the red spotted grouper industry. Real-time fluorescence quantitative PCR technology and protein expression technology will be used to analyze the expression characteristics of the egg-type aromatase gene in different tissues, developmental stages and sexes of the red spotted grouper. Through bioinformatics analysis and dual luciferase reporter gene screening, the promoter function region of the egg-type aromatase gene of the red spotted grouper will be screened. The transcriptional activity of different promoter fragments will be studied to preliminary investigate the regulatory mechanism of the egg-type aromatase gene of the red spotted grouper. The results of this study are expected to provide a theoretical basis and experimental data for further revealing the reproductive regulation mechanism of the red spotted grouper.
