title: GSM3330877: d12_2; Pyrus ussuriensis; RNA-Seq
library_construction_protocol: The adventitious roots of the four developmental stages were sampled, flash frozen on Liquid nitrogen, and RNA was harvested using EASYspin reagent. Illumina TruSeq RNA Sample Prep Kit was used with 1 ug of total RNA for the construction of sequencing libraries. RNA libraries were prepared for sequencing using standard Illumina protocols.
