title: ginseng root 48 transcriptome
design: RNA quality index (RQI) was determined using the Experion Automated Electrophoresis System (Bio-Rad, Hercules); only those having RQI  8.0 out of 10.0 for perfect integrity were used for RNA-seq library construction. RNA-Seq library for each sample was prepared using the TruSeqTM RNA Sample Prep Kit v2 (illumina, San Diego).
