RNA-seq analysis of maternal provisioning and zygotic genome activation during early Atlantic halibut (Hippoglossus hippoglossus) embryogenesis

This study investigates transcriptomic changes across early embryonic development in Atlantic halibut (Hippoglossus hippoglossus), spanning stages from unfertilized eggs to late epiboly. RNA-seq was performed on whole embryos from three females at seven developmental stages to characterize maternal mRNA provisioning and zygotic genome activation. The data provide a comprehensive overview of gene expression dynamics during halibut embryogenesis and represent a resource for understanding early developmental regulation in teleosts.

本研究聚焦大西洋庸鲽（Hippoglossus hippoglossus）早期胚胎发育过程中的转录组变化，覆盖从未受精卵至晚期外包（epiboly）的全部发育阶段。研究针对来自3个雌性个体的7个发育阶段的全胚胎样本开展RNA测序（RNA-seq）实验，以解析母源mRNA的储备与合子基因组激活过程。本数据集全面展现了庸鲽胚胎发生过程中的基因表达动态特征，可为理解真骨鱼类（teleosts）的早期发育调控机制提供关键研究资源。
