Figure 7. The 5′ flanking sequence of the o2 gene of liao2345/o2-2.

The capital letters represent the sequences of the rbg transposon, and the lower case letters represent the flanking sequences of the O2 gene. Red arrows indicate two inverted repeats of the rbg transposable element, and the blue arrows indicate two direct repeats, one of which was created by the insertion of rbg.
