摘要： The blood acts as a transfer channel for a variety of factors in the whole body. The ricefield eel(Monopterus albus) is a protogynous hermaphrodite vertebrate. Until now, no research has reported an analysis of the blood transcriptome during the process of sexual development in the ricefield eel. In this study, the transcriptome sequencing of blood samples from male and female ricefield eels was completed with a total of 34.70 Gb clean data. The clean data of each sample all reached 5.23 GB, and the percent of the Q30 basic group was 88.62% and above. A total of 106,369 unigenes were obtained after assembly, including 13,296 unigenes with a length of more than 1 kb. Further functional annotation analysis showed that there are 28,522 unigenes that can be annotated. The annotations of genes with differential expression revealed that there were 563 genes with significant differential expression in the blood of male and female ricefield eels, including 91 upregulated genes and 472 downregulated genes. Among which, 14 genes may be closely related to sex differentiation, the qPCR was used to confirmed the expression pattern of those genes and result shown that 11 genes were downregulated and 3 genes were upregulated, consistent with the results of our RNA-Seq analysis. This blood transcript dataset will open future research avenues on ricefield eel sex development and differentiation.
