Transcriptome of Chinese sturgeon (Acipenser sinensis) from the hypothalamic-pituitary-gonad axis in two sex development stages

Here, the HPG axis transcriptomes of A. sinensis were sequenced using Illumina HiSeq 2000 and 4000 platforms. A total of 271.19 Gb filtered data from 45 samples belonging to 15 individuals (six individuals in stage I, six males and three females in stage II) were obtained, and 74.50% of 121,952 assembled unigenes were annotated to the non-redundant (NR), Swiss-Prot, Kyoto Encyclopedia of Genes and Genomes (KEGG), Cluster of Orthologous Groups of proteins (COG), InterPro, Gene Ontology (GO) and NT databases. Additionally, 78,770 unigenes contained complete open reading frames (ORFs). A total of 51,570 simple sequence repeats (SSRs) were detected, and the number of differentially expressed genes (DEGs) from 1,531 to 34,439 in 18 pairwise comparisons were identified for HPG samples of male and female A. sinensis in two stages. We reported the first integrated transcriptome data from HPG samples of male and female A. sinensis in stage I and II of gonadal development. These data offer valuable resources for research into reproductive regulation and the HPG axis interaction in A. sinensis and other sturgeons. the HPG axis transcriptomes of A. sinensis were sequenced using Illumina HiSeq 2000 and 4000 platforms
