Linear representation of the genes, ORFs, and IS elements of the circular plasmid pNRC100. The plasmid is divided into five sections, the small single-copy region, the right IR (red arrow), the large single-copy region (divided into two sections), and the left IR (red arrow). IS elements (arrows indicating orientation) are shown along with a scale in nucleotides and genes and ORFs on each DNA strand are shown below. Identities and orientation of genes (red or green arrows) and ORFs (purple or blue arrows) are indicated. All 1965 pNRC100 ORFs five codons or larger have been assigned numerical designations on the basis of location; however, only those ORFs judged to represent probable genes are shown for clarity.
