Fig. 4

Genome divergence plots of the 13 cp. genomes with J. leptostachya as a reference based on visualized global alignment. Grey arrows and thick black lines above the alignment indicate genes with their orientations and directions. Protein-coding regions (exon), non-coding regions (CNS) and untranslated regions (UTR) are marked in red, blue and green, respectively. A cut-off of 70% identity was used for the plots, and the Y-scale represents the percent identity from 50–100%
