Abstract

Abstract: Here, we report the complete mitochondrial genome of an Australian raven ( Corvus coronoides ). The mitogenome of C. coronoides was characterised as a circular molecule of 16, 925 bp in length encoding a typically conserved structure similar to those of other Corvidae. It consisted of 13 protein-coding genes (PCGs), two rRNA genes, and 22 tRNA genes, with all protein-coding sequences commencing with methionine. The lengths of 12S ribosomal RNA and 16S ribosomal RNA were 980 bp and 1600 bp, respectively, and were located between tRNA-Phe and tRNA-Leu. The overall base composition of the mitogenome of C. coronoides was slightly higher AT (56.0%) content than GC (44.0%). A phylogenetic tree using available complete mitogenome sequences of the family Corvidae revealed a close evolutionary relationship of C. coronoides with the now extinct Chatham raven ( C. moriorum ), a large songbird that was native to the Chatham Islands east of New Zealand.
