The complete chloroplast genome sequence of an economically important plant, Zanthoxylum bungeanum (Rutaceae)

The complete chloroplast genome (cp genome) sequence of Zanthoxylum bungeanum has been assembled from Illumina pair-end sequencing. This genome was 158,401 bp in length, consisting of a pair of inverted repeats (IRs) of 27,446 bp which separated by a large single copy (LSC) region and a small single copy (SSC) region (85,898 and 17,611 bp in length, respectively). There are 132 genes, including 87 protein-coding genes (78 PCG species), 37 rRNA genes (30 rRNA species) and eight tRNA genes (four tRNA species) in the cp genome. The overall GC content of the whole genome is 38.6 %, while the corresponding values of the LSC, SSC, and IR regions are 36.87, 33.51 and 42.54 %, respectively. Phylogenetic analysis indicated that the cp genome of Z. bungeanum is closely related to that of congeneric Zanthoxylum piperitum.
