    摘要:

    本研究对罗氏沼虾胚胎的卵裂期I、卵裂期II、囊胚期、原肠期、前无节幼体、无节幼体、前蚤状幼体、蚤状幼体8个发育阶段进行转录组测序,共得到156.37 Gb clean data,预测得到22964个unigenes。对罗氏沼虾8个不同发育阶段的胚胎样品的unigenes进行两两比较分析,获得各个时期之间的差异表达基因数量在587到8620之间。对差异表达基因进行GO富集分析,上调表达基因主要富集在与细胞发育、生长、运动相关的GO功能类别,下调表达基因主要富集在与细胞的翻译调控、趋化、抗氧化、排毒活性相关的GO功能类别。KEEG富集分析发现,差异表达基因的pathway主要富集在与细胞的生长发育以及正常的生理生化过程相关的代谢途径。本研究为罗氏沼虾胚胎研究提供了转录组信息资源。

    Abstract:

    In this study, transcriptome sequencing was performed on eight developmental stages of Macrobrachiumrosenbergii embryos, including cleavage stage I, cleavage stage II, blastocyst stage, gastrula stage, naupliusproprionalis, naupliusproprionalis, and flea like larva. A total of 156.37 Gb clean data was obtained, and 22964 unigenes were predicted. A two-by-two comparative analysis of the embryonic samples from eight different developmental stages of R. rosenbergii was performed, and the number of differentially expressed genes in 8 embryonic samples of M. rosenbergii at different development stages was between 587 and 8620. GO enrichment analysis of differentially expressed genes showed that up-regulated expressed genes were mainly enriched in GO functional categories related to cell development, growth, and motility, and down-regulated expressed genes were mainly enriched in GO functional categories related to translational regulation, chemotaxis, antioxidant, and detoxification activities of cells. KEEG enrichment analysis found that pathways of differentially expressed genes were mainly enriched in metabolic pathways related to cell growth and normal physiological and biochemical processes. This study provides a transcriptome information resource for the study of R. rosenbergii embryos.
