Characterization of the complete chloroplast genome of Rohdea wattii (Asparagaceae).

ABSTRACT: As a kind of rare plant with important medicinal value and breeding value, Rohdea wattii usually grow in dark and damp places. In this study, we reported the complete chloroplast genome of R. wattii. 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 R. wattii 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 R. wattii chloroplast genome is 37.61%. In addition, a total of 132 genes were identified in the whole genome of R. wattii, which include 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Finally, by constructing a phylogenetic tree to analyze the phylogeny of R. wattii, and it indicated that R. wattii and Rohdea chinensis are a close evolutionary relationship.
