Mitochondrial genomes of the bird genus Piranga: rates of sequence evolution, and discordance between mitochondrial and nuclear markers.

ABSTRACT: We report the characteristics of the mitochondrial genomes of 22 individuals in the bird genus Piranga, including all currently recognized species in the genus (n = 11). Elements follow the standard avian mitogenome series, including two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, 13 protein coding genes, and the mitochondrial control region. Excluding tRNA sequences, sequence divergence rate was lowest in rRNA genes and highest in genes encoding NADH (specifically ND1, ND2, ND3) and the control region. Gene trees assembled from 16 elements (non-tRNAs) varied greatly in topological concordance compared to the recognized species tree (based on thousands of nuclear loci), with no one gene tree precisely recovering all relationships in the genus. We also investigat
