Abstract
Citrus huanglongbing, putatively caused by the associated bacterium ‘Candidatus Liberibacter asiaticus’, is the greatest threat to the world citrus industry today. The bacterium is spread locally and regionally by the citrus psyllid Diaphorina citri, and also can be disseminated by propagation of contaminated scion budwood that is grafted to the appropriate rootstock. The planting of ‘Ca. Liberibacter asiaticus’-free trees is a component of a comprehensive strategy to manage huanglongbing. In c

Colonization of Dodder, Cuscuta indecora, by ‘Candidatus Liberibacter asiaticus’ and ‘Ca. L. americanus’

Abstract
Huanglongbing, or citrus greening, threatens the global citrus industry. The presumptive pathogens, ‘Candidatus Liberibacter asiaticus’ and ‘Ca. L. americanus’ can be transferred from citrus to more easily studied experimental hosts by using holoparasitic dodder plants. However, the interaction between ‘Candidatus Liberibacter’ spp. and the dodder has not been studied. We combined quantitative polymerase chain reaction with electron microscopy to show that only 65% of tendrils of Cuscuta indeco
