Abstract:
In this study, we first sequenced and described the complete mitochondrial genome and phylogeny of Psittacula alexandri. The whole genome of P. alexandri was 16,883 bp in length, and contained 14 protein-coding genes, 22 transfer RNA genes, 2 ribosome RNA genes, and 1 non-coding control regions. The overall base composition of the mitochondrial DNA was 30.87% for A, 22.36% for T, 32.82% for C, and 13.95% for G, with a GC content of 46.77%. A phylogenetic tree strongly supported that P. alexandri closely related with Eclectus roratus by highly probability.
