Figure 1.

Gene map of Nephroselmis cpDNA and compared patterns of gene partitioning in Marchantia and Nephroselmis cpDNAs. Thick lines represent the two copies of the IR (IR_A and IR_B). The relative orientation of the small single-copy (SSC) and large single-copy (LSC) regions is arbitrary in the representation shown. Genes on the outside of the map are transcribed in a clockwise direction; those inside the map are transcribed counterclockwise. The color-code denotes the genomic regions containing the homologous genes in Marchantia: cyan, LSC region; magenta, SSC region; and yellow, IR. Transfer RNA genes are indicated by the one-letter amino acid code followed by the anticodon in parentheses. The ORFs unique to Nephroselmis cpDNA are not indicated (see GenBank accession no. AF137379).
