Argopecten属扇贝种间杂交后代育性决定机制
Mechanisms determining interspecific hybrid sterility in Ar-gopecten scallops
摘要
Abstract
Molluscs are vital to the global fishery industry and livelihood,accounting for approximately 56%of the world's mariculture production.The hermaphroditic bay scallop(Argopecten irradians irradians)and Peruvian scallop(Argopecten purpuratus)are shellfish with high nutritional and economic value.The interspecific hybrids between the two exhibit remarkable advantages in growth,with Argopecten breeding possessing great potential.Nevertheless,most hybrids are infertile,limiting further development and the large-scale application of scallop crossbreeding technology.This review summarizes the potential mechanisms underlying such sterility from genetic and environmental perspectives.Insufficient energy supply,dysregulation of mitosis and meiosis,elevated levels of reactive oxygen species(ROS)and apoptosis,obstruction of gametogenesis and maturation due to mutated mito-chondrial and nuclear genes,aberrant nucleocytoplasmic interactions,defective epigenetic modifications,and changes in the environmental temperature may be the most critical reasons.Besides,EGFR may also play a key role in regulating fertility in hybrid scallops.This review may provide new insights into understanding the mechanisms determining interspecific hybrid sterility in scallops and lay a theoretical foundation for the large-scale hybrid breeding of shellfish.It is expected to provide related references to promote the healthy development of the aqua-culture industry.关键词
