^aThe length of operon is counted in bp. The column of operon is named with the abbreviation of gene family. The connections of genes are indicated by a plus sign. The gene order in the operon is based on the full-length transcript. Genome Position means the location of operon in the new version of S.polyrhiza 7498 chloroplast genome. PSII means photosystem II and PSI is photosystem I
