Characterization of the complete chloroplast genome of Sanicula rubriflora F. Schmidt ex Maxim

Abstract

Sanicula rubriflora refers to a kind of edible wild herbs, which possesses reputed medicinal value. Chloroplasts (cp) is essential organelle in plant cells and has a genome that can be inherited autonomously. The complete chloroplast genome of S. rubriflora was assemble and annotated in the present study. It was a circular molecular genome with a size of 155,700 bp in length, which has a typical quadripartite structure. For instance, a large single-copy (LSC) of 85,979 bp and a pair of inverted repeats (IRs) of 26,333 bp were disconnected by a small single-copy (SSC) of 17,053bp. A total of 130 genes have been annotated, including 86 protein-coding genes (PCGs), 36 transfer RNA genes (tRNAs) and 8 ribosomal RNA genes (rRNAs). The total GC content of the complete chloroplast genome reached 37.9%. A maximum likelihood phylogenetic analysis with the reported chloroplast genomes revealed that S. rubriflora is most closely related to Saniculachinensis in the phylogenetic relationships.
