Abstract Background While many genome sequences are complete transcriptomes are less well characterized. We used both genome-scale tiling arrays and massively parallel sequencing to map the Caenorhabditis elegans transcriptome across development. We utilized this framework to identify transcriptome changes in animals lacking the nonsense-mediated decay NMD pathway. Results We find that while the majority of detectable transcripts map to known gene structures 5 of transcribed regions fall outside current gene annotations. We show that 40 of these are novel exons. Using both .
