Abstract:
Zygophyllum brachypterum Karelin & Kirilov belongs to Zygophyllaceae and is mainly distributed in the desert regions of Central Asia, Mongolia, and Northwest China. The species is valuable in exploring the adaptations of Zygophyllaceae plants to salt stress in ecological environments. In this study, we report the complete chloroplast (cp) genome of Z. brachypterum. The entire cp genome was 104590 bp in length, with a large single-copy region (LSC, 79170 bp), a small single-copy region (SSC, 16778 bp), and two inverted repeats (IRa/IRb) of 4321 bp each. A total of 106 genes were detected, among which seven were located in the IRs, and 65, 30, and 4 were protein-coding, tRNA, and rRNA genes, respectively. Notably, eleven genes encoding the subunits of NAD(P)H dehydrogenase complex (NDH) were absent. Phylogenetic analysis indicated that Z. brachypterum belonged to Zygophylloideae (Zygophyllaceae). Furthermore, it was closely related to Z. fabago and Z. kansuense.
