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

The species contains two pathovars, neither of which is native to Europe: X. o. pv. oryzae and X. o. pv. oryzicola.[1]

Xanthomonas oryzae epidemics can cause yield losses ranging from 2-74%,[2] and the bacteria can be carried on rice seeds, causing further disease spread.[3]

The host resistance gene, Xa21, from Oryza longistaminata, is integrated into the genome of Oryza sativa for its broad-range resistance to rice leaf blight caused by X. o. pv. oryzae.[4]
