Complete chloroplast genome sequence of Zanthoxylum nitidum (Rutaceae) an important medicinal shrub

摘要

Zanthoxylum nitidum (Rutaceae) is a scandent prickly shrub and widely distributed in South China. It’s well known for its valuable medicinal values due to contains some important secondary metabolites. Here, we first report and characterize its complete chloroplast genome based on Illumina paired-end sequencing data. The complete plastid genome was 157,253 bp, which contained inverted repeats (IR) of 27,618 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 84,382 bp and 17,635 bp, respectively. The cpDNA contains 132 genes, comprising 87 protein-coding genes, 37 tRNA genes, 8 rRNA genes. The overall GC content of the plastome is 38.5%. The phylogenetic analysis of 20 selected chloroplast genomes demonstrated that Z. nitidum is closely related to the congeneric Z. bungeanum.
