Frequencies of plastid genomes of flowering plants with and without correct IR annotations. Displayed are yearly frequencies of genome records between 2014 and 2020. a The frequency of records with complete and equal-length IR annotations in which these annotations are correct (light gray) or incorrect (dark gray) given the genome sequences. b The frequency of genome records without complete IR annotations in which IRs do (light gray) or do not (dark gray) exist in the genome sequences
