Characterization of the complete mitochondrial genome of Ilisha striatula (Clupeiformes, Pristigasteridae) and phylogenetic studies of Clupeiformes

摘要

In this study, the complete mitochondrial genome of Ilisha striatula is presented, and we also discussed its mitochondrial characteristics. The full length of the mitochondrial genome was 16,847?bp, including 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNA genes, one non-coding control region (CR), and one origin of replication on the light-strand. The total nucleotide composition of the mitochondrial genome was 31.11% A, 24.62% T, 29.10% C, 15.16% G, and AT was 55.73%. The phylogenetic tree based on the ML method supported the placement of I. striatula in a close relationship with I. elongata. These data contribute to a better understanding of the systematics of the Pristigasteridae.
