The complete chloroplast genome sequence of Aphanamixis polystachya.

The first complete chloroplast genome (cpDNA) sequence of Aphanamixis polystachya was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 160,236 bp in length, contains a large single-copy region (LSC) of 87,484 bp and a small single-copy region (SSC) of 18,670 bp, which were separated by a pair of inverted repeats (IR) regions of 27,040 bp. The genome contains 130 genes, including 85 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 37.6%, and the corresponding values of the LSC, SSC, and IR regions are 35.6%, 31.8%, and 42.8%, respectively. Further phylogenomic analysis showed that A. polystachya and Cipadessa cinerascens clustered in a clade in family Meliaceae.
