Scholarcy highlights

  • Amur catfish is extensively distributed and cultured in Asian countries
  • The assembled transcriptome of Amur catfish consisted of 74,840 transcripts
  • Putative sex-specific transcripts were identified and sex-specific expression of the representative genes was verified by RT-PCR
  • The ovary-biased genes were mainly enriched in pathways such as RNA transport and ribosome biogenesis in eukaryotes
  • Our data provide a valuable genomic resource for further investigating the genetic basis of sex determination, sex differentiation and sexual dimorphism of catfish
