The complete chloroplast genome sequence of Xylia xylocarpa

Abstract

The first complete chloroplast genome (cpDNA) sequence of Xylia xylocarpa was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 161,288 bp in length, contains a large single copy region (LSC) of 89,186 bp and a small single copy region (SSC) of 19,354 bp, which were separated by a pair of inverted repeats (IR) regions of 26,370 bp. The genome contains 131 genes, including 86 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 36.6%, and the corresponding values of the LSC, SSC, and IR regions are 34.1%, 30.8%, and 42.8%, respectively. Further phylogenomic analysis showed that X. xylocarpa clustered in a unique clade in Caesalpinioideae subfamily.
