Xanthomonas oryzae is a species of proteobacteria. The major host of the bacteria is rice.[1]

The species contains two pathovars which are non-European: Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola.[1]

Host resistance gene, Xa21,from Oryza longistaminata is integrated into the genome of Oryza sativa for the broad range resistance of rice blight disease caused by Xanthomonas oryzae pv. oryzae [2]
