The complete chloroplast genome sequence of Zanthoxylum undulatifolium Hemsl. (Rutaceae)

Zanthoxylum undulatifolium is an excellent economic tree species with important medical value. This study reports the first complete chloroplast genome sequence of Z. undulatifolium. Its whole chloroplast genome is 158,400 bp in length, including a large single-copy (LSC) region of 85,898 bp, a small single-copy (SSC) region of 17,610 bp, and two inverted repeat (IR) regions of 27,446 bp. The chloroplast genome contains a total of 132 genes, comprising 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the chloroplast genome is 38.46%, with the corresponding values in the LSC, SSC, and IR regions are 36.87%, 33.51%, and 42.55%, respectively. Phylogenetic analysis revealed the sister relationship between Z. undulatifolium and Z. bungeanum.
