Xanthomonas oryzae pv. oryzae (Xoo),? is the rice (Oryza sativa) pathogenic bacterium in which genome sequencing has revealed very extensive race differentiation. The whole genome sequence of its native host has also been completed, and analysis of the host?parasite interaction on the basis of the two genomes can be expected to be useful.

We present here the complete genome sequence of strain MAFF 311018 (T7174) of an apparently highly evolved plant-pathogenic bacterium Xoo; this sequence provides clues to the endless race between rice and Xoo.
