Complete plastome sequence of Nephelium topengii (Merr.) H. S. Lo (Sapindaceae): an endemic species in Hainan

Nephelium topengii is an evergreen tree of the Sapindaceae family, which can be used as timber. Here, we report and characterize the complete plastome of N. topengii. The complete plastome is 162,944 bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 30,092 bp, a large single-copy (LSC) region of 85,909 bp and a small single-copy (SSC) region of 16,851bp. The plastome contains 130 genes, consisting of 80 unique protein-coding genes, 30 unique tRNA gene, 4 unique rRNA genes (5S rRNA, 4.5S rRNA, 23S rRNA and 16S rRNA). The overall A/T content in the plastome of N. topengii is 62.30%. The complete plastome sequence of N. topengii will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Sapindaceae.
