Moss contains tens of small protein-coding sORFs. (A) Venn diagram showing the distribution of the identified translatable sORFs among three types of moss cells. (B) Length distribution of various groups of small protein-coding sORFs. (C) Distribution of small protein-coding sORFs based on the suggested classification. (D) Binary heat map showing evidence of translation for sORFs and proteins in multicoding genes in three moss tissues. G, N, and P correspond to gametophores, protonemata, and protoplasts, respectively. (E) Heat map showing expression levels (log10[RPKM]) for the lncRNAs (left) carrying sORFs (lncRNA-sORFs) and binary heat map showing evidence of translation (determined as whether a peptide was identified [brown] or not [gray] in MS data) for the corresponding lncRNA-sORFs (right) in three moss tissues: gametophores (G), protonemata (N), and protoplasts (P).
