Characterization of the complete chloroplast genome of (Asparagaceae).

As a kind of rare plant with important medicinal value and breeding value, usually grow in dark and damp places. In this study, we reported the complete chloroplast genome of . We used a variety of bioinformatics analysis methods to analyze and visualize the chloroplast genome and phylogenetic relationships. A typical quadripartite structure was observed in the chloroplast genome of with a genome size of 156,487 bp. The length of the large single-copy region (LSC) was 84,969 bp, which was the longest region among the four regions; the second longest was the Inverted repeat region (IR) with 26,451 bp in length; and the smallest was the small single-copy region (SSC) with 18,616 bp in length. The overall GC content of chloroplast genome is 37.61%. In addition, a total of 132 genes were identified in the whole genome of , which include 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Finally, by constructing a phylogenetic tree to analyze the phylogeny of , and it indicated that and are a close evolutionary relationship.
