Alignment of the ycf15 region in six representative angiosperms. Atropa and Nicotiana represent the uninterrupted form. Codons highlighted in green represent start codons as annotated in the published genomes Atropa and Nicotiana. Codons highlighted in red represent stop codons in frame with those start codons. Although the sequence is highly conserved, it is not an open reading frame in most taxa.
