摘要： Schnabelia tetrodonta is a medicinal plant used in traditional Chinese medicine. However, the molecular biology data of the species was too scarce to bioprospect the medicinal species. In this study, the first complete chloroplast genome (cp) of S. tetrodonta was sequenced and assembled based on the next generation sequencing. The cp genome is 157,004 bp in length, including a large single-copy (LSC) region of 83,605 bp, a small single-copy (SSC) region of 36,899 bp, and a pair of inverted repeat (IR) regions of 18,250 bp each. The genome encodes 134 genes, including 90 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The GC content of whole genome is 37.80%. The phylogenetic analysis based on 20 complete cp sequences (19 genome sequences from the Teucrioideae of Lamiaceae and an outgroup of Ipomoea purpurea) revealed that S. tetrodonta was closely related to S. oligophylla.
