The complete chloroplast genome sequence of <i>Tamarix arceuthoides</i> Bunge and <i>Tamarix ramosissima</i> Ledeb. (Tamaricaceae)

<i>Tamarix</i> L. is of great ecological and economic significance in arid desert ecosystems. This study reports the complete chloroplast (cp) genomic sequences of <i>T. arceuthoides</i> Bunge and <i>T. ramosissima</i> Ledeb., which are currently unknown, by high-throughput sequencing. The cp genomes of <i>T. arceuthoides</i> 1852 and <i>T. ramosissima</i> 1829 were 156,198 and 156,172 bp in length, respectively, and contained a small single-copy region (SSC: 18,247 bp), a large single-copy region (LSC: 84,795 and 84,890 bp, respectively), and a pair of inverted repeat regions (IRs: 26,565 and 26,470 bp, respectively). The two cp genomes possessed 123 genes arranged in the same order, including 79 protein-coding, 36 tRNA, and eight rRNA genes. Of these, 11 protein-coding genes and seven tRNA genes contained at least one intron. The present study found that <i>Tamarix</i> and <i>Myricaria</i> are sister groups with the closest genetic relationship. The obtained knowledge could provide useful information for future phylogenetic, taxonomic, and evolutionary studies on Tamaricaceae.
