Figure 5

Percentage identity plots and gene order surrounding the clp P gene. Gene identities between C. japonica and C. taitungensis (A), and between C. taitungensis and six other plants including C. japonica (B-G) are shown by MultiPipMaker. The directions of arrows indicate the transcribed sense/antisense strands. The colored boxes show the group of genes and the relevant coding region of each gene. Mutual comparisons of the clpP gene between C. japonica and C. taitungensis (A, B), show the first and third exon are completely absence in the C. japonica cp genome. For the gene order surrounding the clpP gene, the clpP to rpl20 gene order is extremely conserved to be co-transcribed in the cp genomes of all the land plants of this study (see Figure 7 for the detailed gene order). On the other hand, the clpP gene in the C. japonica cp genome is found halfway between the psbJ and accD gene, and is clearly not co-transcribed with the rps12 and rpl20 genes.
