Abstract

Abstract: The grain Chenopodium quinoa Willd. is the main traditional food of Inca aboriginal, which was a native grain in South American Andes Mountains, the edible and cultivation history of which has been more than five thousand years. In this study, we sequenced the complete chloroplast genome of C. quinoa on the Illumina platform by shotgun genome skimming method. The complete chloroplast genome of C. quinoa was 152, 087 bp in length with the GC content 37.2%, which was comprised of a large single copy (LSC) region of 83, 570 bp, a small single copy (SSC) region of 18, 107 bp, and a pair of inverted repeats (IRA/IRB) of 25, 205 bp. The chloroplast genome encoded 133 genes including 88 protein-coding genes, 37 tRNA genes and eight rRNA genes. Phylogenetic analysis constructed using the maximum likelihood (ML) method strongly supported the monophyly of each genus in the family Chenopodiaceae, and the genus Chenopodium is sister to Spinacia as a cluster, which closely grouped to Dysphania.
