The complete chloroplast genome sequence of Artemisia ordosica

Abstract

Artemisia ordosica is one of the important plants in succession of psammophytes in sandy (desert), it is a high ecological, economic and scientific research value. The chloproplast is photosynthetic organelles that provide energy for green plants. In this study, we reported the complete chloroplast (cp) genome sequence of A. ordosica, which were assembled using high-throughput sequencing technology. The results showed that the total cpDNA genome of A. ordosica is 151,209 bp in length, consisting of a large single copy (LSC) region of 82,980 bp, a small single copy (SSC) region of 18,303 bp, and a pair of inverted repeat regions (IRa and IRb, 24,963 bp each). Among all genes, the content of GC is 37.4%. The LSC, SSC, and IRs are 58.44%, 12.10%, and 33.02% of the A. ordosica cpDNA genome length respectively. Furthermore, the genome contained a total of 113 genes, comprising 79 protein-coding genes, 4 rRNA genes, and 29 tRNA genes. A phylogenetic analysis based on 21cpDNA genomes suggested that the A.ordosica is closely related to A. scoparia.
