title: GSM2844055: M17_5; Zea mays; miRNA-Seq
library_construction_protocol: Total RNA was extracted by using TRIzol® reagent (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's instructions, and RQ1 DNase (Promega, Madison, WI, USA) was used to remove contaminating genomic DNA. The quality and quantity of the purified RNA was monitored at the ratios of A260/A280 and A260/230 on SmartSpec Plus Spectrophotometer (BioRad, Philadelphia, PA, USA). RNA integrity was further verified by 1.5% agarose gel electrophoresis. Three μg of total RNA was used for small RNA cDNA library preparation with Balancer NGS Library Preparation Kit for small/microRNA (GnomeGen, San Diego, CA, USA) based on manufacturer's instruction. Briefly, RNAs were ligated to 3' and 5' adaptor sequentially, reverse transcribed to cDNA and PCR amplified. Whole library was applied to 10% native PAGE gel electrophoresis and bands corresponding to miRNA insertion were cut and eluted.  After ethanol precipitation and washing, the purified small RNA libraries were quantified with Qubit Fluorometer (Invitrogen, Carlsbad, CA, USA), used for cluster generation and applied to Illumina GAIIx (Illumina, San Diego, CA, USA) 73 nt single-end sequencing or Illumina NextSeq 500 76 nt pair-end sequencing according to the manufacturer's instructions. The small RNA libraries sequencing was perfomed in ABLife, Inc. (Wuhan, China).The smallRNA libraries sequencing was perfomed in ABLife, Inc. (Wuhan, China).
