The raw sequence reads were mapped to the reference plastome sequences. A) C. deserticola; B) C. salsa; C) C. sinensis; D) C. tubulosa. The X-axis shows the plastome positions. The Y-axis shows the depth. The Y-axis shows the coverage depth of the mapped reads. Fig. S2. The dot plots showing the self-2-selfalignment of the four Cistanche plastomes sequences. The plots were generated using Gepard. A) C. deserticola; B) C. salsa; C) C. sinensis; D) C. tubulosa. Fig. S3. A schematic map of the Cistanche deserticola plastome.The first circle shows the species name and specific information regarding the genome (length, GC content, and the number of genes) from the center going outward. The second circle shows the length of the corresponding single short copy (SSC), inverted repeat (IRa and IRb), and large single-copy (LSC) regions from the center going outward. The third circle shows the GC content. The outer circle shows the gene names and their optional codon usage bias in parentheses.The genes are colored based on their functional categories. Genes inside andoutside of the circle are transcribed in clockwise and counterclockwise directions, represented with arrows. Fig. S4. A schematic map of the Cistanche salsa plastome.

Identity plot comparingthe plastid genomes of C. deserticola, C. salsa, C. sinensis,C. tubulosa and C. phelypaea using Rehmannia glutinosa as a reference sequence. The vertical scale indicates the percentage of identity(50% to 100%), using a 50% identity cutoff. The horizontal axis indicates the coordinates in the plastomes. Genome regions are color-coded as protein-coding, rRNA, tRNA, intron, and conserved non-coding sequences (CNS). Fig. S8. Synteny analyses of plastomes for five Cistanche species. Each horizontal black line represents a genome, with conserved regions connected with colored blocks. The plastome sequence of C. deserticola was used as the reference. Fig.S9. Synteny analyses of five Cistanche plastomes compared with Rehmannia glutinosa. Each horizontal black line represents a genome, with conserved regions connected with colored block. The plastome of R. glutinosa was used as the reference. Fig. S10. Extent of the gene rearrangements of 5 Cistanche plastomes. Locally collinear blocks of the sequences are colour-coded and connected by lines. Fig. S11. Maximum likelihood (ML) Phylogenetic tree of 36 Orobanchaceae species.
