摘要: In this study, we obtained the complete mitochondrial genome sequence of Sphyraena jello and analyzed its phylogenetic position. The complete mitogenome of S. jello is 16 699 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. Among the 37 genes, 28 were encoded on heavy strand, while 9 were encoded on light strand. The overall base composition was 28.97% for A, 16.14% for G, 29.64% for C, and 25.25% for T, with a higher A + T content (54.22%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested that S. jello is a sister species to Sphyraena barracuda in the family Sphyraenidae. This result should be useful for understanding the genetic structure, molecular evolution, and phylogeny of S. jello and related species.
