title: GSM2690803: 9h-w22-1; Zea mays; RNA-Seq
library_construction_protocol: Forty-eight samples (4 genotypes, 4 time points, 3 biological replicates) were subjected for total RNA extraction using SV Total RNA Isolation Kits (Promega, Dübendorf, Switzerland). 1 μl of total RNA was checked by Nanodrop 1000 Spectrophotometer to estimate the RNA concentration. The quantity and quality in RNA sequencing were determined using Qubit® 1.0 Fluorometer (Thermo Fisher Scientific, Wilmington, USA) and Bioanalyzer 2100 (Agilent, Waldbronn, Germany). The TruSeq Stranded mRNA Sample Prep Kit (Illumina, Inc., Hayward, USA) was used for library preparation. 1 μg of total RNA per sample was ribosome depleted and then subjected for synthesizing double-strand cDNA. Each cDNA sample was fragmented, end-repaired, polyadenylated and then ligated with TruSeq adaptor that contains the index for multiplexing. The cDNA fragments containing TruSeq adapters at the both ends were enriched with PCR reaction. The enriched libraries were quantified and qualified, and then normalized to 10nM. The TruSeq SR Cluster Kit v4 cBot (Illumina, Inc., Hayward, USA) was used for cluster generation using 8 pM of pooled normalized libraries. Sequencing was performed on the Illumina HiSeq2500 at single end 125 bp using the TruSeq SBS Kit v4.
