The complete plastome sequence of Atractylodes macrocephala (Asteraceae: Cardueae), an important medicinal plant in East Asia

Abstract

Atractylodes macrocephala is one of the most commonly used herbs in China, which is famous for its high medicinal value. In this study, we analyzed and characterized the complete plastome sequence of A. macrocephala. Sequence analysis indicated that the entire genome is 153,265 bp in length, consisting of a large single-copy (LSC, 84,311 bp) and a small single-copy (SSC, 18,674 bp) region separated by a pair of inverted repeat (IR) regions of 25,140 bp for each. The genome contains 107 unique genes, including 80 different protein-coding genes, 23 tRNA genes, and 4 rRNA genes. The overall GC content of the genome is 37.7%. The phylogenetic analysis revealed a monophyletic Atractylodes and Cardueae. This research reports the complete plastome genome of Atractylodes macrocephala, which provides a better understanding of this important herb.
