Figure 2. Gene map of A. melilotoides chloroplast genome. Genes shown inside the circle indicate that the direction of transcription is clockwise, while those shown outside are counterclockwise. Different groups of functional genes are indicated in different colors. The GC content is shown in the dashed area in the inner circle.

Figure 3. Phylogenetic relationship between Astragalus melilotoides and other 34 species of Astragalus based on the complete cp genome sequences from the NCBI database by using MEGA-X. Among this species, A. sinicus (OM287552) (Ke et al. Citation2022), A. galactites (MZ504977) (Ding et al. Citation2021), A. membranaceus var. membranaceus (KX255662) (Wang et al. Citation2016), A. laxmannii (MT786136) (Liu et al. Citation2020), and A. complanatus (MZ221114) (Yang Citation2021) have been published. Oxytropis arctobia and Oxytropis bicolor were chosen as the outgroups. The number on each node represents bootstrap values.
