Abstract
The Amur cork tree (Phellodendron amurense) is an endangered deciduous tree species with high medicinal and economic values. In this study, its complete chloroplast genome was determined using high-throughput Illumina sequencing technology. The cp genome of P. amurense is 158,442 bp in length, and contains a pair of inverted repeat (IR) regions of 26,999 bp each, separated by a large single-copy (LSC) region of 86,160 bp and a small single-copy (SSC) region of 18,284 bp. It encodes 113 gene species (including 79 PCG, 30 tRNA and 4 rRNA species) with 21 of them occurring in double copies. The nucleotide composition is asymmetric (30.5% A, 19.6% C, 18.8% G & 31.1% T) with an overall A+T content of 61.6%. Phylogenetic analysis supports the morpho-taxonomy of the order Sapindales, and indicates that P. amurense is relatively closely related to the genus Zanthoxylum (as represented by Zanthoxylum bungeanum, Zanthoxylum piperitum and Zanthoxylum schinifolium).
