The chloroplast genome of Fallopia aubertii (Polygonaceae) from Xining, China

Abstract

Fallopia aubertii (L.Henry) Holub (Polygonaceae), a woody plant with a voluble stem, is used as a folk herbal medicines for the treatment of gout, fever and pneumonia. To better understand the molecular genetics of F. aubertii, its complete chloroplast genome was sequenced and annotated. The assembled chloroplast genome is a circular 160,951 bp sequence consisting of large single copy (87,279 bp) and small single copy (13,394 bp) regions, separated by two inverted repeat regions (30,860 bp each). The genome contains 131 genes including 86 protein-coding, 37 tRNA and 8 tRNA genes. Phylogenetic analysis based on the complete chloroplast genome showed that F. aubertii is more closely related to M. australis than to F. sachalinensis, which exhibited a polyphyletic relationship with respect to F. aubertii. These results require further analyses. This study provides additional data for reconstructing species relationships in Fallopia.
