RESUMO

Polygonaceae is a large family of medicinal herbs that includes many species used as traditional Chinese medicine, such as Per sicaria per foliata. Here, we sequenced the complete chloroplast genome of P. per foliata using Illumina sequencing technology with the purpose of providing a method to facilitate accurate identification. After being annotated, the complete chloroplast genome of P. per foliata was compared with those of Fagopyrum tataricum, Per sicaria chinensis, Fagopyrum dibotrys, and Fallopia multiflora. The complete chloroplast genome of P. per foliata is 160 730 bp in length, containing a small single-copy region of 12 927 bp, a large single-copy region of 85 433 bp, and a pair of inverted repeat regions of 62 370 bp. A total of 131 genes were annotated, including 8 rRNA genes, 34 tRNA genes, and 84 protein-coding genes. Forty-two simple sequence repeats and 55 repeat sequences were identified. Mutational hotspot analyses indicated that five genes (matK, ndhF, ccsA, cemA, and rpl20) could be selected as candidates for molecular markers. Moreover, phylogenetic analysis showed that all the Polygonaceae species formed a monophyletic clade, and P. per foliata showed the closest relationship with P. chinense. The study provides valuable molecular information to accurately identify P. per foliata and assist in its development and application.
