Figure 1.

Circular representation of the Xanthomonas oryzae pv. oryzae genome. Rings illustrate, from outside to inside: protein coding genes (forward strand), protein coding genes (reverse strand), TAL effectors (green) and IS elements (red), and GC-skew plot showing (G-C)/(G+C) in 10 kilobase windows. Positive values of GC-skew indicate the leading strand of replication, negative values the lagging strand.
