Expected inversion event in the C. japonica cp genome. The expected inversion corresponds with the gene segment I in Figure 8. Genes are represented by boxes extending above or below the base-line depending on the direction of transcription. The colored boxes indicate the same gene units among the seven cp genomes, including C. japonica. The tRNA anti-codon is abbreviated in the six plant cp genomes excluding C. japonica. The character highlighted in red represents the duplicated trnQ-UUG in the C. japonica cp genome. The pseudogene is indicated by ψ (pseudo-).
