Figure 1. (a). The whole plant of P. asiatica. (b). The flowers of P. asiatica. (c). The original plant of P. depressa. (d). The specimen of P. asiatica.
Table 1. The primary characteristics of the P. asiatica chloroplast genome.
Figure 2. Circular map of the chloroplast genome of P. asiatica. Genes drawn inside the circle are transcribed clockwise, while those outsides are transcribed counter-clockwise. Genes are color-coded to imply functional groups. The dark gray area in the inner circle corresponds to the GC content while the light gray corresponds to the AT content of the genome. The SCC, LSC, IRa and IRb regions are noted in the inner circle.

Figure 6. Comparison of the Cp genome sequences of P. asiatica, P. depressa, P. ovata, P. lagopus, P. grandiflorus, and A. thaliana generated using mVISTA. Gray arrows symbolize the position and direction of the genes. Red and blue areas indicate intergenic and genic regions, respectively. Black lines represent regions of sequence identity with P. asiatica, with a 50% identity cutoff. Dashed rectangles denote highly divergent regions when P. asiatica compared to P. depressa, P. ovata, P. lagopus, P. grandifloras, and A. thaliana.
Figure 7. Comparison of the borders of the LSC, SSC, and IR regions of P. asiatica, P. lagopus, P. depressa, P. media, P. ovata, P. auriculata and Arabidopsis thaliana.
Figure 8. Phylogenetic tree plotting using ML method, based on aligning the completed chloroplast genome sequences of Plantago asiatica L. and 17 other representative species. The numbers above the nodes are support values with ML bootstrap values. The distance bar was implied by the ML method.
