Group 13 alignment and percent identity of (A) uORF and (B) mORF sequences. Representative eukaryotic species were aligned using Muscle and displayed using Jalview. Panel A alignment is restricted to the first 50 amino acid positions, which excludes the full 92 amino acid uORF of Cycas rumphii. All other uORFs are shown in their entirety. Panel B alignment is restricted to the first 100 amino acid positions of the mORFs. See main text for abbreviated species names and Genbank accession number, cDNA clone number, or genome identifier.
