## Abstract

Symplocos tanakana Nakai (1918) is a deciduous shrub or small tree with multiple applications. It is native to China and belongs to the Symplocaceae family. This study presents the complete mitochondrial genomic sequence of S. tanakana. This is the first member of the Symplocaceae family for which the complete mitochondrial genomic sequence is being reported. The mitochondrial genome was assembled into a single 877,273-bp circular molecule that contains 290 open reading frames (ORFs) and 68 annotated genes, including 38 protein-coding, 3 ribosomal RNA, and 27 transfer RNA genes. Phylogenetic analysis of the mitochondrial genomes of 33 species from 17 plant families using the maximum likelihood method showed evolutionary relationships. These findings enhance our understanding of the S. tanakana mitochondrial genomic features and provide a basis for the development of S. tanakana molecular markers.
