The complete chloroplast genome of Asarum heterotropoides Fr. Schmidt var. mandshuricum (Maxim.) Kitag. (Aristolochiaceae), a traditional Chinese medicine herb

Abstract

The complete chloroplast genome of A. heterotropoides var. mandshuricum reported herein was a circular DNA molecule of 160,262 bp in length. The typical quadripartite structure of the genome consisted of a pair of inverted repeats (IRs) of 27,262 bp separated by a large single-copy (LSC) region of 88,927 bp and a small single-copy region (SSC) of 16,811 bp. The overall GC content of the genome is 38.45%, with 36.7%, 33.1%, and 43.0% in LSC, SSC, IR regions, respectively. The cp genome encoded 125 genes, including 83 protein-coding genes, 34 tRNA genes, and 8 rRNA genes. 138 SSRs were identified in the genome. Phylogenetic anlysis showed the position of A. heterotropoides var. mandshuricum is closely related to A. heterotropoides.
