| Extraction protocol |
Total RNA was isolated from tissues dissected from Oregon R animals in biological duplicates. Strand-specific RNA-seq libraries were prepared using pre-release Directional mRNA-seq Library Kits (Illumina). Briefly, poly(A)+ RNA was isolated by oligo-dT selection, fragmented, and treated with phosphatase and polynucleotide kinase to repair the ends. 3’ and 5’ RNA adapters were then sequentially ligated to the RNA fragments and reverse transcribed using a primer complementary to the 3’ linker. The libraries were then PCR amplified. One nanogram of the strand-specific RNA-Seq libraries were reamplified by PCR using a primer complementary to the 5’ adapter and a second primer complementary to the 3’ adapter with six T residues at the 3’ end. After 10 rounds of amplification, the 3’ primer with the T extension was replaced with a 3’ primer complementary to the adapter with a 5’ extension containing a 6 nt index sequence and a sequence complementary to the flow cell primer. After an additional 15 rounds of amplication, the libraries were quantitated, 10-12 libraries were pooled together and sequenced.

Reads were split into the respective samples using the index sequence. Reads were simultaneously aligned to the dm3 genome and splice junctions using Bowtie (Langmead, 2010) and SPA (Graveley et al., 2011). To identify polyA-spanning reads, reads that failed to align to the genome were examined to identify cases where the first read contained >10 A residues at the 3’ end or the second read contained >10 T residues at the 5’ end. The terminal A or T residues were trimmed from the reads and uniquely aligned polyA-spanning reads identified using Bowtie.
