The complete mitochondrial genome of Norfolk Robin (Petroica multicolor: Petroicidae), an endemic endangered species in Norfolk Island

Abstract

Norfolk Robin (Petroica multicolor) is mainly distributed in the islands of the southwest Pacific Ocean. It is an endangered species with a declining population and needs urgent protection. Here, we report the first complete mitochondrial genome of Norfolk Robin in the Petroicidae family. The mitochondrial genome is a typically circular genome with a total length of 16,861 bp, and it contains 13 protein-coding genes, 22 tRNA, and 2 rRNA genes. The GC content is 46.3%, and the percent of A, C, G, and T is 29.9%, 31.8%, 14.5%, and 23.7%, respectively. Phylogenetic analysis based on mitochondrial genomes fully supported that the white-eared catbird is closely related to P. goodenovii. The complete mitochondrial genome obtained from the current study can provide more genomic resources and guidance for the conservation biology, taxonomy and population genetics of Norfolk Robin.
