Abstract

Abstract: Rheum lhasaense (Polygonaceae) is one of the genuine medicinal herbs in Qinghai-Tibet Plateau, China. Here we report the first chloroplast (cp) genome of R. lhasaense using Illumina NovaSeq 6000 platform. The length of its complete cp genome is 161, 820 bp, containing four sub-regions. A large single copy region (LSC) of 87, 086 bp and a small single copy region (SSC) of 12, 814 bp are separated by a pair of inverted repeat regions (IRs) of 30, 960 bp. The complete cp genome of R. lhasaense contains 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the cp genome is 37.4%. The phylogenetic analysis, based on 28 cp genomes, suggested that R. lhasaense is closely related to R. acuminatum and R. pumilum.
