A Wide Variety of sPEP Transcripts.

Transcripts of sPEPs harbor many sORFs (<100 amino acids; blue arrows), though only a few sORFs have been experimentally characterized (orange arrows). All sORFs starting with AUG and consisting of at least six codons in sense direction are displayed. Interior ORFs located within the same frame of a longer ORF are omitted, except for the SC-PEPTIDE. Only the 5′ part of the SC-PEPTIDE transcript and the miPEP transcripts is displayed (indicated by a double slash). A red arrow represents mature miRNA found from one arm of a hairpin; a green arrow represents mature miRNA (with asterisk) formed from the opposite arm of a hairpin.
