Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CaLas), is the No. 1 killer of citrus trees worldwide. HLB causes billions of dollars in annual economic losses to the global citrus industry. At present, no HLB-resistant cultivars and no effective therapeutic agents is available for citrus farmers. Citrus canker disease, caused by Xanthomonas citri pv.citri (Xcc), is another devastating disease in the citrus industry, which can harm almost all citrus cultivars and is currently on the outbreak trend.
