Dataset Information

Dataset for sequencing and de novo assembly of the European endangered white-clawed crayfish (Austropotamobius pallipes) abdominal muscle transcriptome.

ABSTRACT: The white-clawed crayfish (Austropotamobius pallipes) is an endangered species in Europe with limited genomic information. Despite its conservation status there is no transcriptomic data available for A. pallipes in public databases. The data here represents the first transcriptome profile of the white-clawed crayfish generated using Illumina stranded RNA sequencing. Pair-end reads were assembled de novo with three separate transcriptome assemblers (Trinity, RNABloom, and RNASpades) followed by transcript assembly reduction and gene reconstruction using the EvidentialGene pipeline. The transcriptome was functionally annotated using InterProScan and genes coding for carbohydrate-active enzymes were identified through the dbCAN2 server. Raw fastq reads and the final version of the transcriptome assembly have been deposited in the NCBI-SRA (SRR10549898) and NCBI-TSA (GICG01) databases.

Project description:BackgroundThe Chinese sturgeon (Acipenser sinensis) is endangered through anthropogenic activities including over-fishing, damming, shipping, and pollution. Controlled reproduction has been adopted and successfully conducted for conservation. However, little information is available on the reproductive regulation of the species. In this study, we conducted de novo transcriptome assembly of the gonad tissue to create a comprehensive dataset for A. sinensis.ResultsThe Illumina sequencing platform was adopted to obtain 47,333,701 and 47,229,705 high quality reads from testis and ovary cDNA libraries generated from three-year-old A. sinensis. We identified 86,027 unigenes of which 30,268 were annotated in the NCBI non-redundant protein database and 28,281 were annotated in the Swiss-prot database. Among the annotated unigenes, 26,152 and 7,734 unigenes, respectively, were assigned to gene ontology categories and clusters of orthologous groups. In addition, 12,557 unigenes were mapped to 231 pathways in the Kyoto Encyclopedia of Genes and Genomes Pathway database. A total of 1,896 unigenes, potentially differentially expressed between the two gonad types, were found, with 1,894 predicted to be up-regulated in ovary and only two in testis. Fifty-five potential gametogenesis-related genes were screened in the transcriptome and 34 genes with significant matches were found. Besides, more paralogs of 11 genes in three gene families (sox, apolipoprotein and cyclin) were found in A. sinensis compared to their orthologs in the diploid Danio rerio. In addition, 12,151 putative simple sequence repeats (SSRs) were detected.ConclusionsThis study provides the first de novo transcriptome analysis currently available for A. sinensis. The transcriptomic data represents the fundamental resource for future research on the mechanism of early gametogenesis in sturgeons. The SSRs identified in this work will be valuable for assessment of genetic diversity of wild fish and genealogy management of cultured fish.
