Figure 2. The phylogenetic tree reconstructed using MEGA based on 21 complete chloroplast genome sequences inferred using the maximum-likelihood (ML) method. All sequences were downloaded from NCBI GenBank. The sequences used for phylogenetic tree construction are as follows: A. cepa (MK335926.1; Huo et al. Citation2019/KM088013.1, KM088014.1, KM088015.1; Kim et al. Citation2015), A. sativum (NC_031829.1/KY363332.1/MK335928.1; Huo et al. Citation2019), A. fistulous (MK335927.1; Huo et al. Citation2019/NC_040222.1; Kim et al. Citation2015/MH926357.1; Yusupov et al. Citation2019), A. koreanum (MT348449.1; Namgung et al. Citation2021), A. ochotense (MT348451.1; Namgung et al. Citation2021), A. senescens (MT348450.1; Namgung et al. Citation2021), A. hookeri (MZ557488.1; Ren et al. Citation2022), A. macrostemon (MK75472.1; Xie et al. Citation2019), A. ampeloprasum (NC_044666.1), Agapanthus coddii (NC_035971.1), and Acorus americanus (EU273602.1). The numbers above the nodes indicate bootstrap support values (with 1000 replicates). The numbers under the nodes indicate the length of each node.
Figure 3. Chloroplast genome map of A. sacculiferum. The center of the map indicates the species name and length of the chloroplast genome. The outer circle represents the genes, and the inner circle represents the size of the IRs, LSC, and SSC, respectively. Genes with diverse functions are shown in different colors. The dark grey plot of the inner circle represents the GC content, and the grey line in middle represents the 50% threshold.

The outer circle represents the gene, and the inner circle represents the size of the IRs, LSC, and SSC, respectively. Genes with diverse functions are shown in different colors. The dark grey plot of the inner circle represents the GC content, and the grey line in middle represents the 50% threshold.
