title: RNA-Seq of Gastrodia elata Bl.
design: 1) By utilizing the structural characteristic that most eukaryotic mRNAs carry a polyA tail, mRNAs with polyA tails were enriched by Oligo(dT) magnetic beads; 2) The purified mRNAs were cleaved into small fragments with fragmentation buffer at a suitable temperature; 3) First-strand cDNAs were produced by reverse transcription using a random hexamer primer; 4) Second-strand cDNAs are synthesizedwhile simultaneously performing end repair and dA-Tailing; 5) Sequencing adapter ligation was performed, followed by DNA magnetic bead purification and fragment selection after ligation was completed to yield a library with 250-350 bp insert fragments; 12) The ligated products were amplified by PCR and purified again using DNA magnetic beads, where the products were solubilized with nuclear-free water.
