Complete chloroplast genome sequence of Liquidambar formosana, an ancient subtropical landscape plant to China

Abstract

Liquidambar formosana (Hamamelidaceae) is a tertiary relic species widely distributed in subtropical areas, and is a common endemic broad-leaved tree species in south China. Here, we report and describe for the first time the complete chloroplast genome of L. formosana based on Illumina double-ended sequencing data. The complete plastid genome was 160,425 bp, which contained inverted repeats (IR) of 26,266 bp separated by a large single-copy (LSC) and a small single-copy (SSC) of 88,971 bp and 18,922 bp, respectively. The cpDNA contains 132 genes, comprising 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the plastome is 37.9%. The phylogenetic analysis of 18 selected chloroplast genomes demonstrated that L. formosana was close to the species Sinowilsonia henryi.
