Abstract:
Here, we describe the budgie's mitochondrial genome sequence, a resource that can facilitate this parrot's use as a model organism as well as for determining its phylogenetic relatedness to other parrots/Psittaciformes. The estimated total length of the sequence was 18,193 bp. In addition to the to the 13 protein and tRNA and rRNA coding regions, the sequence also includes a duplicated hypervariable region, a feature unique to only a few birds. The two hypervariable regions shared a sequence identity of about 86%.
