- Xanthomonas oryzaepv. oryzae, or commonly known as Xoo infection, cause huge yield losses to rice cultivation throughout the world.
- Xoo causes a serious bacterial leaf blight disease in rice. It is also known as Bacterial blight. Xoo is a gram-negative bacteria.
- Centre for Plant Molecular Biology (CPMB) have uncovered the mechanism by which rice is treated with cellulase, a cell wall degrading enzyme secreted by Xoo which induces rice immune responses and protects rice from subsequent infections by Xoo.
