Characterization of the complete chloroplast genome of medicinal plant Rheum officinale (Polygonaceae)

Abstract The complete chloroplast (cp) genome of Rheum officinale Baill. was determined based on the Illumina Sequencing data. The cp genome is 161,563？bp in length. The overall G？+？C content of the cp genome was 37.31%. The R. officinale cp genome contains 129 genes, including 84 protein-coding genes, eight rRNA genes (four rRNA species), and 37 tRNA genes (20 tRNA species). A neighbour-joining phylogenetic tree clarified that the cp genome of R. officinale was closely related to that of R. palmatum in Polygonaceae
