Chloroplast genome sequencing and phylogenetic analysis of Tetrapanax papyrifer (Hook.) K. Koch (Araliaceae)

Tetrapanax papyrifer (Hook.) K. Koch is an important medicinal plant in Chinese Yao medicine. In this study, the complete chloroplast genome was sequenced using high-throughput sequencing technology. Its complete chloroplast genome spans 156,165 bp in total length, comprising a large single-copy region of 86,237 bp and a small single-copy region of 17,956 bp, separated by a pair of inverted repeat regions (25,986 bp each). Phylogenetic analysis based on chloroplast genomes revealed that the genomic structure of T. papyrifer shows similarities with species from the genus Heptapleurum in the Araliaceae family. The presented chloroplast genome will facilitate further phylogenetic analyses and inform conservation strategies for this species.
