design: RNA sequencing libraries were prepared from 2g of total RNA using the TruSeq Kit (Illumina, Inc.) with the following modification. Instead of purifying poly-A RNA using poly-dT primer beads, we removed ribosomal RNA using the Ribo-Zero rRNA Removal Kit (Illumina, Inc.). All other steps were performed according to themanufacturer's protocols. RNAseq libraries were analyzed for QC and average size of inserts was approximately 200 to 300 bp.
