The complete chloroplast genome sequence of Zanthoxylum armatum

Abstract The first complete chloroplast genome sequences of Zanthoxylum armatum were reported in this study. The cpDNA of Z. armatum is 158,579？bp in length, contains a large single copy region (LSC) of 85,780？bp and a small single copy region (SSC) of 17,598？bp, which were separated by a pair of inverted repeat (IR) regions of 27,598？bp. The genome contains 133 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 38.5%. Phylogenetic analysis of 18 chloroplast genomes within the family Rutaceae suggests that Z. armatum is closely related to Zanthoxylum schinifolium
