The complete mitochondrial genome of (Osteichthyes:Cyprinidae).

Day 1871 is a rare specie of fish inhabit clear forest streams and rivers. In order to discuss the phylogenetic position of , the mitochondrial genome was obtained by sequencing. The genome was 16,587 bp in length with an accession number OM203155. The AT contents were 56.59%. The location and composition of genes are consistent with published Cyprinids containing 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 main non-coding regions. Sequence analysis showed that the mitochondrial genome of has high sequence homology with other cyprinid fishes. Phylogenetic tree results showed that is most closely related to . The mitochondrial sequence is of great significance for fish conservation, taxonomic status and resource exploitation.
