In recent decades, the decapod aquaculture industry has grown significantly in many parts of the world. Despite this progress, production levels still fall short of market demands, indicating a need for further efforts to increase the production. Investigations into the molecular mechanisms underlying embryonic development in decapods provide valuable insights into the complex embryonic development processes of this economically and ecologically important animal group. In this review, we explore the molecular mechanisms underlying decapod embryonic development, focusing on key genes, signaling pathways, and microRNAs (miRNAs) involved in the embryogenesis. Numerous genes have been identified that regulate various aspects of embryogenesis including egg activation, maternal-to-zygotic transition (MZT), mesoderm development, segmentation, nervous system development, sex determination, germline development, and exoskeleton formation. We also discuss the pivotal role of signaling pathways such as Hedgehog, Wnt, Notch, MAPK, TGF-β, Jak-STAT, VEGF, and Ecdysteroid in the regulation of embryogenesis. Additionally, this review identifies current research gaps in decapod embryogenesis and proposes directions for future investigation. This review is anticipated to be especially beneficial for researchers delving into the molecular mechanisms driving embryonic development in decapods.

十足类甲壳类动物胚胎发育的分子机制


近几十年来，十足类水产养殖业在世界许多地方都取得了显著增长。尽管取得了这些进展，但生产水平仍未达到市场需求，这表明需要进一步努力提高产量。对十足类动物胚胎发育的分子机制的研究为这个具有重要经济和生态意义的动物群体的复杂胚胎发育过程提供了有价值的见解。在这篇综述中，我们探讨了十足体胚胎发育的分子机制，重点关注胚胎发生中涉及的关键基因、信号通路和 microRNA （miRNA）。已经确定了许多调节胚胎发生各个方面的基因，包括卵子活化、母体到合子转换 （MZT）、中胚层发育、分割、神经系统发育、性别决定、种系发育和外骨骼形成。我们还讨论了 Hedgehog、Wnt、Notch、MAPK、TGF-β、Jak-STAT、VEGF 和 Ecdysteroid 等信号通路在胚胎发生调节中的关键作用。此外，本综述确定了当前十足类胚胎发生的研究空白，并提出了未来研究的方向。预计本综述对深入研究驱动十足类胚胎发育的分子机制的研究人员特别有益。
