The complete plastid genome sequence of Panax notoginseng, a famous traditional Chinese medicinal plant of the family Araliaceae

Abstract

We report complete nucleotide sequence of the Panax notoginseng chloroplast genome using next-generation sequencing technology. The genome consists of 156 324 bp containing a pair of inverted repeats (IRs) of 26 105 bp, which was separated by a large single-copy region and a small single-copy region of 86 082 bp and 18 032 bp, respectively. The P. notoginseng cp genome encodes 114 unigenes (80 protein-coding genes, 4 rRNA genes, and 30 tRNA genes), in which 18 are duplicated in the IR regions. The genic regions account for 51.1% of whole cp genome, and the GC content of the plastome was 38.1%. A phylogenomic analysis of the 10 complete chloroplast genomes from Araliaceae using Hydrocotyle verticillata outgroup showed that P. notoginseng is closely related to P. ginseng that belongs to the genus Panax.
