Characterization of the complete plastome of Atriplex centralasiatica (Chenopodiaceae), an annual halophytic herb

Abstract

Atriplex centralasiatica, an annual halophytic herb, is one of the most important Chinese herbal medicines, forages and indicator plants for saline-alkali soil. In this study, we report the complete plastome of A. centralasiatica. The plastome was 152,237 bp in length and comprises a large single-copy region (83,721 bp), a small single-copy region (18,096 bp), and a pair of inverted repeats (25,210 bp). It encodes 113 unique genes, including 79 protein-coding genes (PCGs), 30 tRNAs and 4 rRNAs. The overall GC content of this plastome was 37.3%. Phylogenomic analysis based on 21 plastomes revealed that A. centralasiatica was closely related to the genus Chenopodium.
