The information given in these tables incorporates a number of changes made to the start and stop points of these genes in order to provide consistency between avian mitochondrial (mt) genomes - see ‘SI2 - Revised Bird Annotations’ file. For full taxon names (plus Latin names, references, accession and GI numbers, database record and submission dates and, where appropriate, revision dates), see ‘SI1 - Bird Taxa List’ file. Three range columns are given: one for paleognaths, one for neognaths and one for all birds. Ranges do not include values from incomplete genes/regions.
(L) = encoded by the L strand. Unknown = the mt genome of this taxon is incomplete and does not include this gene/region. > = incomplete region/genome, full length unknown. Gray shading - this feature (length, start or stop codon) is conserved among paleognaths or among neognaths. Purple shading - this feature is conserved in most of the paleognath or the neognath taxa; those that differ are shaded (and the differing values are indicated in purple in the range columns).
Table 1. Length (in amino acids), start and stop codons of avian mitochondrial protein-coding genes
The length of each gene includes the start but not the stop codon (i.e. these genes are treated as ending after the last amino acid-encoding codon). The length of NADH3 does not include the extra nucleotide found in many of the taxa. T-- and TA- = incomplete stop codons. R and Y (in the range columns) indicate purine (A/G) and pyrimidine (C/T) respectively.
Table 2. Length (in nucleotides) of avian mitochondrial control regions, intergenic spacers and complete genomes
The lengths of the intergenic spacers include the stop codons of the protein-coding genes (i.e. protein-coding genes are treated as ending after the last amino acid-encoding codon). N/A = Not applicable (i.e. this taxon does not have this gene/region arrangement). + = gene/region order is reversed in the CrTinamou (i.e. tRNA-Pro (L) /Control Region). # = ‘tRNA-Glu (L) /Additional
Non-Coding Region’ and ‘Additional Non-Coding Region/tRNA-Phe’ in the broadbill, falcon and buzzard. - = 0 (except in the range columns, in which ‘0’ is used while ‘-‘ is used to indicate the range). x overlap = an overlap of x nucleotides in length. Light gray shading - these features are conserved as a result of the way the start and stop positions of the 12S and 16S rRNA genes, the control region and the additional non-coding region are determined.
Table 3. Length (in nucleotides) of avian mitochondrial tRNA and rRNA genes
Both the single-letter and the three-letter code are given for each tRNA (e.g. F, Phe).
