title: GSM5231149: seed_Ver3_miRNA; Brassica rapa subsp. pekinensis; miRNA-Seq
library_construction_protocol: Total RNA was extracted using Trizol reagent (Invitrogen, CA, USA) following the manufacturer's procedure. The total RNA quantity and purity were analysis of Aglient 2100 Bioanalyzer and RNA 6000 Nano LabChip Kit (Agilent, CA, USA) with RIN number >7.0. Approximately 5 µg of total RNA were used to prepare nine small RNA librariesaccording to the protocol of TruSeq Small RNA Sample Prep Kits (Illumina, San Diego, CA, USA).
