Complete mitochondrial genome of Yellow-browed warbler Phylloscopus inornatus inornatus (Passeriformes: Sylviidae).

Yellow-browed warbler Phylloscopus inornatus inornatus (Passeriformes: Sylviidae) is a small insectivorous leaf-gleaning bird which breeds in forests of the east Palaearctic. In this study, we used PCR-based method to determine the complete mitochondrial genome (mtDNA) of this warbler species. The complete mtDNA is a 16,875 bp circular molecule, containing 37 typical genes and an extra pseudo-control region. The gene order differs from the standard gene order in birds, but similar to genus Sylvia and Acrocephalus, which has the remnant CR2 gene order. All protein-coding genes start with a typical ATG codon. The termination codon is usually the standard TAA, but may be TAG (Cyt b and ND6), AGG (COI) or incomplete T-(COIII and ND4). All tRNAs have the typical clover-leaf structure, except the dihydrouridine (DHU) arm of tRNASer (AGN) and tRNALys (CUN), which forms a simple loop. The non-coding region contains some intergenic spacers, a control region and an extra pseudo-control region.
