Project description:In this study, we presented the complete mitochondrial genome of Tringa semipalmata. The circular genome is 16,603?bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosome RNA genes and 1 D-loop control regions. The overall nucleotide composition is as follows: 31.2% A, 25.2% T, 29.9% C and 13.6% G, with a total G?+?C content of 43.53%. The phylogenetic tree was constructed to validate the taxonomic status of T. semipalmata, exhibiting it a close relationship to other Tringa species.
