Abstract

The pikeperch (Sander lucioperca L.) is one of the most economically important freshwater species and has been recently explored as a potential candidate for aquaculture. To facilitate pikeperch research, we sequenced its transcriptome and developed a set of microsatellite markers. We conducted Illumina RNA-sequencing and obtained over 50 million reads from a pooled cDNA library of different tissues. The clean reads were de novo assembled into 56,746 transcripts, with an average length of 1474 bp. The annotation analysis demonstrated 37,386 transcripts (65.9%) with homologous sequences in the NCBI Nr protein database. Of these annotated transcripts, 18,576 sequences were successfully assigned into Gene Ontology (GO) terms, 23,566 transcripts into the Cluster of Orthologous Groups (COG), and 12,081 transcripts to 322 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Totally, 16,368 SSRs (≥10 bp) were detected from 11,921 unigenes. The validation of randomly selected 300 SSR markers demonstrated 87.0% of the markers can be successfully amplified, suggesting RNA-Seq is an efficient tool for the development of molecular markers. This study provides not only a valuable transcriptomic resource, but also a set of SSR markers for basic as well as applied research in pikeperch.
