RESUMO
The northern red-shouldered macaw, Diopsittaca nobilis, is listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora Appendix II. Here, we report for the first time the complete mitochondrial genome of D. nobilis. This new sequence is 16,992 base pairs (bp) in length and includes 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and a single non-coding control region. The overall nucleotide composition of this sequence consists of 30.40% A, 14.00% G, 23.60% T, and 32.00% C. The phylogenetic relationships suggested that the mitogenome of D. nobilis is close to that of three other macaw species. Our results provide useful mitogenomic information to support further studies on the phylogeny and taxonomy of Psittaciformes.
RESUMO
In this study, we sequenced and characterized the complete mitochondrial genome of Green-winged macaw (Ara chloropterus) listed on CITES Appendix II. The circular double-stranded genome was 16,991 bp in size and included 22 transfer RNA (tRNA) genes, 13 protein-coding genes (PCGs), two ribosomal RNA genes (rrnL and rrnS), and one non-coding control region (D-loop). Both order and arrangement of genes were identical to those of other animal mitogenomes. The base content was 30.00% A, 14.38% G, 23.27% T, and 32.35% C, with an A + T content of 53.37%. Furthermore, phylogenetic analysis indicated that A. chloropterus is closely related to the Blue and yellow macaw (A. ararauna).
