is an aquatic species found distributed worldwide. It is found in the Yangtze River of China, where the commercial fishing of this valuable catadromous aquatic species has been banned. As an important member of the phylum Arthropoda, grows by molting over its whole lifespan. The central nervous system of plays an important regulatory role in molting growth. Nevertheless, there are no reports on the regulatory mechanisms of the nervous system in during the molting cycle. In this study, a comparative transcriptome analysis of thoracic ganglia at post-molt and inter-molt stages was carried out for the first time to reveal the key regulatory pathways and functional genes operating at the post-molt stage. The results indicate that pathways and regulatory genes related to carapace development, tissue regeneration, glycolysis and lipolysis and immune and anti-stress responses were significantly differentially expressed at the post-molt stage. The results of this study lay a theoretical foundation for research on the regulatory network of the nervous system during the post-molt developmental period. Detailed knowledge of the regulatory network involved in molting can be used as a basis for breeding improved species, recovery of the wild population and prosperous development of the artificial breeding industry.
是一种分布于全球的水生物种。在中国长江发现了它，在那里，这种有价值的降河洄游性水生物种的商业捕捞已被禁止。作为节肢动物门的重要成员，在其整个生命周期中通过蜕皮生长。的中枢神经系统在蜕皮生长中起重要的调节作用。然而，关于在蜕皮周期中神经系统的调节机制尚无报道。在本研究中，首次对蜕皮后期和蜕皮间期的胸神经节进行了比较转录组分析，以揭示在蜕皮后期起作用的关键调节途径和功能基因。结果表明，与甲壳发育、组织再生、糖酵解和脂肪分解以及免疫和抗应激反应相关的途径和调节基因在蜕皮后期有显著差异表达。本研究结果为蜕皮后期发育期间神经系统调控网络的研究奠定了理论基础。对蜕皮调控网络的详细了解可作为改良物种育种、野生种群恢复和人工养殖产业繁荣发展的依据。
