is a generalized genus of the Polygonaceae family that includes various herbaceous plants. In order to provide aid in understanding the evolutionary and phylogenetic relationship in at the chloroplast (cp) genome-scale level, we sequenced and annotated the complete chloroplast genomes of four species using next-generation sequencing technology and CpGAVAS. Then, repeat sequences, IR contractions, and expansion and transformation sites of chloroplast genomes of four species were studied, and a phylogenetic tree was built using the chloroplast genomes of . The results indicated that the chloroplast genome construction of also displayed characteristic four types of results, comparable to the published chloroplast genome of recorded angiosperms. The chloroplast genomes of the four plants are highly consistent in genome size (159,015 bp-163,461 bp), number of genes (112 genes, including 78 protein-coding genes, 30 tRNA genes, and 4 rRNA genes), gene types, gene order, codon usage, and repeat sequence distribution, which identifies the high preservation among the chloroplast genomes. The phylogenetic tree was recreated by a full sequence of the chloroplast genome, which illustrates that the , , and are divided into the same branch, and belongs to . The precise system site of lots base parts requires further verification, but the study would provide a basis for developing the available genetic resources and evolutionary relationships of .
