Bacterial leaf blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a destructive disease in rice fields. Can Tho is one of the most important rice-growing areas in the Mekong Delta, which is vulnerable to climate change, making the disease more damaging in this region. Deployment of resistance genes is considered an economic and eco-friendly approach to control the disease. However, Xoo exists in different races with diverse reactions on different resistance genes. | Population diversity of Xanthomonas oryzae pv. oryzae causing bacterial leaf blight in rice fields of Can Tho
