RNA-seq of Urechis unicinctus: adult gonad
For transcriptome sequencing, four tissues, including intestines, gonads, blood, and muscle were collected from the same individual and stored at liquid nitrogen. RNA was extracted from these tissues and used for transcriptome sequencing, respectively. The cDNA paired-end libraries were prepared and sequenced on an Illumina Hiseq X sequencer (Paired-end 350bp reads).
