Abstract
Helwingia japonica (Thunb.) Dietr. is an important medicinal and ornamental plant of Helwingia from the family (Helwingiaceae). It is mainly distributed in the provinces south of the Yellow River Basin in China. In this study, we sequenced, assembled and annotated the chloroplast genome of Helwingia japonica in order to provide genetic resources for this important medicinal and ornamental plant. Helwingia japonica chloroplast genome is a circular structure with 158,469 bp. It contained a large single-copy region (LSC) (87,715 bp), a small copy region (SSC) (18,620 bp), and two inverted repeats (IR) (26,067 bp each). It has 89 unique genes (45 protein-coding genes, 36 transfer RNA genes, and 8 ribosomal RNA genes). At last, we constructed a phylogenetic tree. The result of phylogenetic analysis indicated that Helwingia japonica and Helwingia chinensis are closely related.
