Abstract
In this study, the complete mitochondrial genome (mitogenome) sequence of Coilia brachygnathus (Clupeiformes: Engraulidae) was determined by long PCR and primer walking methods. The complete mitochondrial genome is 16,677 bp in length and contains 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes as well as a displacement loop (D-loop). The overall base composition of the genome is A(31.21%), T(26.25%), C(27.06%), G(15.48%). The mitogenome of C. brachygnathus displayed novel gene order arrangement compared with published Coilia ectenes to date. The mitogenome would contribute to resolving phylogenetic position and interrelationships of Coilinae.
