Ultrastructure and Transcriptomic Analysis Reveal Alternative Pathways of Zona Radiata Formation in <i>Culter alburnus</i> with Different Spawning Habits.

ABSTRACT: Spawning diversity plays an essential role in fish survival and reproduction, which contributes to the exceptional diversity of teleosts among vertebrates. Different zona radiata structures reflect the adaptability of fish to the environment of spawning and early embryonic development. The morphological and transcriptional characteristics of fish follicle development between different spawning habits, particularly the zona radiata variations, have been poorly documented. In this study, we integrated histology and transcriptomics to investigate the differences in the zona radiata structure and gene expression profiles among follicles from different spawning habits of Culter alburnus. Our results revealed that stage Ⅲ was the crucial period for zona radiata thickening and structure di
