'Candidatus Liberibacter americanus', associated with citrus huanglongbing (greening disease) in São Paulo State, Brazil.
Symptoms of huanglongbing (HLB) were reported in São Paulo State (SPS), Brazil, in March 2004. In Asia, HLB is caused by 'Candidatus Liberibacter asiaticus' and in Africa by 'Candidatus Liberibacter africanus'. Detection of the liberibacters is based on PCR amplification of their 16S rRNA gene with specific primers. Leaves with blotchy mottle symptoms characteristic of HLB were sampled in sever...

متن کاملQuantitative real-time PCR for detection and identification of Candidatus Liberibacter species associated with citrus huanglongbing.
Citrus huanglongbing (HLB, ex greening) is one of the most serious diseases of citrus. Different forms of the disease are caused by different Candidatus Liberobacter species, Candidatus Liberibacter asiaticus (Las), Ca. L. africanus (Laf) and Ca. L. americanus (Lam). The pathogen is transmitted by psyllid insects and by budding with contaminated plant materials. The vector psyllid Diaphorina ci...
