Additional file 1: of Gene annotation errors are common in the mammalian mitochondrial genomes database

Table S1. Analysis of gene arrangements of 304 mammalian mitochondrial genome. Gene arrangements of the mammalian species compared in this analysis as annotated at NCBI with Reference IDs shown for each. The numeral in parentheses indicates the number of species belonging to each group. Each gene is assigned a number 1â 37 at the top of the Table which is then used to describe the annotated gene arrangement for each species. Each gene is transcribed left-to-right as shown except for those with a minus (â ) symbol to indicate opposite orientation. The arrangement shared by all three monotreme and human mitochondrial genomes has long been inferred to be the ancestral condition for mammals. Highlighting indicates all deviations from that ancestral arrangement according to the NCBI sequence records, with green being confirmed by this work, red being errors of gene arrangement according to our analysis, brown being errors of gene boundary annotation according to our observation, orange being a failure to annotate a gene that we determined to be present, and gray being a gene missing wholly or in large part because the sequence is not present in the file. trnY for Aotus nancymaae, colored red here, is also in error for gene boundary errors. 1Extinct species.
