Atraphaxis jrtyschensis (Polygonacae) is an endangered desert shrub endemic to China in Xinjiang province with great ecological importance for sand fixation. However, its genomic resources are still very limited. Here, we generated the first chloroplast (cp) genome of A. jrtyschensis using genome skimming sequencing. The whole cp genome is 164,192 bp and comprises 130 genes, including 83 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 2 pseudogenes (rpl23). The overall GC content of A. jrtyschensis cp genome is 37.5%. The phylogenic analysis placed A. jrtyschensis at the base of Trib Rumiceae, which contained the genera Rheum and Oxyria. This study will be useful for future researches to investigate the conservation genetics and potential applications in sand fixation of the endangered desert shrub.
