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]

Rice blast is the most important disease concerning rice crops in the world. Since rice is an important food source for much of the world, its effects have a broad range. It has been found in over 85 countries across the world and reached the United States in 1996. Every year the amount of crops lost to rice blast could feed 60 million people.
