| contents | Comparative transcriptomic characterization of the ovary in the spawning process of the mud crab Scylla paramamosain Shisheng Tu Guohong Yu Fuqiang Ge Rui Xu Zhongwen Jin Xi Xie Dongfa Zhu Development, Growth & Differentiation AbstractOviposition is induced upon mating in most insects. Spawning is a physiological process that is fundamental for the reproduction of Scylla paramamosain. However, the molecular mechanisms underlying the spawning process in this species are poorly understood. Herein, comprehensive ovary transcriptomic analysis was conducted at the germinal vesicle breakdown stage (GVBD), spawning stage, 0.5 h post‐spawning stage, and 24 h post‐spawning stage of S. paramamosain for gene discovery. A total of 67,230 unigenes were generated, and 27,975 (41.61%) unigenes were annotated. Meanwhile, the differentially expressed genes (DEGs) between the different groups were identified, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis was subsequently conducted. These results suggested that octopamine (OA) and tyramine (TA) could induce oviposition, while dopamine (DA) and serotonin (5‐hydroxytryptamine [5‐HT]) inhibit oviposition. The 20‐hydroxyecdysone (20E) and methyl farnesoate (MF) signal pathways might be positively associated with oviposition. Furthermore, numerous transcripts that encode neuropeptides and their G‐protein‐coupled receptors (GPCRs), such as CNMamide, RYamide, ecdysis‐triggering hormone (ETH), GPA2/GPB5 receptor, and Moody receptor, appear to be differentially expressed during the spawning process. Eleven unigenes were selected for qRT‐PCR and the pattern was found to be consistent with the transcriptome expression pattern. Our work is the first spawning‐related investigation of S. paramamosain focusing on the ovary at the whole transcriptome level. These findings assist in improving our understanding of spawning regulation in S. paramamosain and provide information for oviposition studies in other crustaceans. 10.1111/dgd.12921 http://onlinelibrary.wiley.com/termsAndConditions#vor |
