The complete chloroplast genome of Ziziphus mairei Dode 1908 (Rhamnaceae), an endangered perennial plant in Yunnan, China

Abstract

Ziziphus mairei Dode 1908 (Rhamnaceae) is a rare and endangered perennial plant in Yunnan, China. In this study, we sequenced, assembled, and annotated the complete chloroplast genome of Z. mairei. The complete chloroplast genome was a closed circular molecule of 161,546 bp with a typical tetrad structure, containing a large single-copy (LSC) region of 89,252 bp, a small single-copy (SSC) region of 19,364 bp, and a pair of inverted repeat (IR) regions of 26,465 bp. A total of 128 genes have been annotated, including 83 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The GC content is 36.7%. Phylogenetic analysis revealed that Z. mairei is closely related to Z. hajarensis, Z. jujuba, and Z. jujuba var. spinosa. Our results provide useful genetic resources for further studies on the conservation and evolution of Z. mairei.
