Complete plastome sequence of Heliciopsis lobata (merr.) Sleum: a Chinese medicinal species in China

Abstract

Heliciopsis lobata, National class II rare and Endangered plant protection, is one of the subtropical important medicinal plants. However, its complete plastome information and systematic position are still unknown. In order to enhance the development of its Chinese medicinal value and deepen the study of it, we report and characterize the complete plastid genome sequence of H. lobata in an effort to provide genomic resources useful to promoting its medicinal value and systematic research. The complete plastome is 160,961 bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 26,455 bp, a large single-copy (LSC) region of 88,929 bp, and a small single-copy (SSC) region of 19,122 bp. The plastome contains 117 genes, consisting of 83 unique protein-coding genes, 30 unique tRNA genes, and 4 unique rRNA genes. The overall A/T content in the plastome of H. lobata is 62.00%. The complete plastome sequence of H. lobata will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies of Proteaceae.
