Abstract

The first complete chloroplast genome (cpDNA) sequence of Afzelia xylocarpa was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 159,115 bp in length, contains a large single-copy region (LSC) of 88,164 bp and a small single-copy region (SSC) of 19,495 bp, which were separated by a pair of inverted repeats (IR) regions of 25,748 bp. The genome contains 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 36.1%, and the corresponding values of the LSC, SSC, and IR regions are 33.7%, 29.6%, and 42.6%, respectively. Further phylogenomic analysis showed that A. xylocarpa, Tamarindus indica, and Crudia harmsiana are clustered in a clade in the Detarioideae subfamily.
