Abstract
In Brazil ‘Candidatus Liberibacter asiaticus’ and ‘Ca. L. americanus’ cause huanglongbing (also known as greening), the most destructive citrus disease. A shift in pathogen prevalence was observed over time, with a disproportional increase in ‘Ca. L. asiaticus’ occurrence. Graft transmission experiments were used for a comparative study of both species using budsticks from symptomatic branches of field-affected trees as inoculum. The plants were inoculated with ‘Ca. L. asiaticus’ or ‘Ca. L. ame

Liberibacters Associated with Citrus Huanglongbing in Brazil: ‘Candidatus Liberibacter asiaticus’ Is Heat Tolerant, ‘Ca. L. americanus’ Is Heat Sensitive

Abstract
In São Paulo State, Brazil, ‘Candidatus Liberibacter americanus’ and ‘Candidatus Liberibacter asiaticus’ are associated with huanglongbing (HLB). Affected municipalities occur mainly in the central and southern regions, where the annual number of hours above 30°C is two to five times lower than that in the extreme northern and western regions. The influence of temperature on sweet orange trees infected with ‘Ca. L. asiaticus’ or ‘Ca. L. americanus’ was studied in temperature-controlled growth c
