Characterization of the complete chloroplast genome of sorrel (Rumex acetosa)

Rumex acetosa, known as sheep's sorrel, red sorrel, sour weed, and field sorrel, is a species of flowering plant in the buckwheat family Polygonaceae. In this study, the complete chloroplast (cp) genome of R. acetosa (Rumiceae) was determined through Illumina sequencing method. The complete chloroplast genome of R. acetosa was 160,269 bp in length and contained a pair of IR regions (30,503 bp) separated by a small single copy region (13,128 bp) and a large single copy region (86,135 bp). This cp genome is encoded with 129 genes including 83 protein-coding genes, 36 tRNA genes, and 8 ribosomal RNA genes. The overall GC content of R. acetosa cp genome is 37.2%. By phylogenetic analysis using Bayesian method, R. acetosa showed the closest relationship with other 2 Rumiceae species, Rheum palmatum and Oxyria sinensis.
