Psolus sp.  transcriptome
RNA from tissues samples was extracted using a Qiagen miRNEasy kit. An Agilent Bioanalyzer 2100 ver. 2.6 was used for quality control prior to library preparation. Samples were then submitted to the Duke Institute for Genome Science and Policy for library preparation with an Illumina TruSeq RNA kit, followed by RNA-Seq sequencing on an Illumina Hiseq 2000 platform (100 BP, paired end).
