Abstract
The complete mitochondrial genome of the white-browed laughingthrush Garrulax sannio was assembled using next-generation sequencing (NGS) technology. The double-stranded circular genome is 17 848 bp in length, including 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), and 2 putative control region. All PCGs are initiated with the ATG codon except for COX1 with GTG as its start codon. Five distinct types of stop codons are present, i.e., AGA (ND5), AGG (COX1 and ND1), TAA (ATP6, ATP8, COX2, CYTB, and ND4L), TAG (ND6), and the incomplete codon T/TA (COX3, ND2, ND3, and ND4). The nucleotide composition is moderately asymmetric (28.94% A, 32.82% C, 15.00% G, and 23.24% T) with an overall GC content of 47.82% (“light strand”). Phylogenetic analysis indicated a close genetic relationship between this species and its congeners G. perspicillatus, G. cineraceus, and G. canorus.
