Distribution of putative smORFs across the chromosomal arms of D. melanogaster (Dm), showing the number of smORFs after filtering for coding DNA sequences (CDSs) and transposons, and the number of Dm smORFs conserved in D. pseudoobscura (Dp). The euchromatin content of each chromosomal arm is indicated in nucleotide base pairs.
