Unravelling Citrus Huanglongbing Disease [PDF]

, 2020
Huanglongbing (HLB) or citrus greening is a disease caused by the unculturable, fastidious, phloem-restrictive, Gram-negative bacterium Candidatus Liberibacter spp. Currently, there are three species linked to the disease. The Asian form associated with Candidatus Liberibacter asiaticus (CLas) is heat-tolerant and can survive well above 30°C.

Simulation and Evaluation of Heat Transfer Inside a Diseased Citrus Tree during Heat Treatment

AgriEngineering, 2021
Heat treatment has been applied in previous studies to treat diseased plants and trees affected by heat-sensitive pathogens. Huanglongbing (HLB) is a heat-sensitive pathogen and the optimal temperature–time for treating HLB-affected citrus trees was ...

Mutations in the SWEET15 Sugar Transporter Gene Affect Response of Citrus to Huanglongbing Disease and Citrus Canker. [PDF]

Mol Plant Pathol
Assays of knockouts in several SWEET genes show that SWEET15 mutations reduce levels of Xanthomonas citri pv. citri and “Candidatus Liberibacter asiaticus” in infected citrus plants, suggesting that SWEET15 is a susceptibility gene. ABSTRACT Bacterial diseases like huanglongbing (HLB) and citrus canker severely impact citrus production. HLB, caused by “
