摘要： Bone morphogenetic proteins (BMPs) are important growth factors belonging to the TGF-(3 superfamily. These factors not only play a vital role in skeleton formation in young fish but also regulate the morphological development of M. asiaticus, with Group II genes regulating morphology mainly during the juvenile stage. This study investigated how BMP genes regulate Myxocyprinus asiaticus development and function and explored the role of the BMP family in fish morphological development. In this study, 43 BMPs were identified and classified into five groups: BMP1/3/11/15 (Group I), BMP12/13/14 (Group II), BMP2/4/16 (Group III), BMP9/10 (Group IV), and BMP5/6/7/8 (Group V). Analyses of the gene structures and conserved motifs revealed the conservation of the BMP gene family in M. asiaticus. In M. asiaticus, gene fragmentation, duplication, and 4R whole-genome duplication events contributed to BMP gene family expansion. Furthermore, expression pattern analysis and qRT-PCR revealed that changes in M. asiaticus BMP gene expression during different developmental stages were due to body size alterations, highlighting the major impact of the BMP gene on body size variation in this species. Our study provides fundamental data for investigating the morphological development of M. asiaticus and lays the framework for understanding the genetic mechanisms of body size variation in scleractinian fishes, with potential applications in the artificial breeding and conservation of M. asiaticus.
