Huanglongbing (HLB), caused by the bacteria 'Candidatus Liberibacter spp', is one of the most destructive diseases for citrus production around the world. Early diagnosis of diseased citrus trees is of utmost importance for the control of HLB. Molecular techniques, such as PCR, offer quick and specific detection and
Candidatus Liberibacter is a genus of Gram-negative bacteria in the Rhizobiaceae family. The term Candidatus indicates that it has not proved possible to maintain this bacterium in culture. Detection of the liberibacters is based on PCR amplification of their 16S rRNA gene with specific primers. Members of the genus are

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
6 Aug 2013 Huanglongbing (HLB) is a systemic disease of citrus caused by phloem-limited bacteria 'Candidatus Liberibacter' spp. with 'Ca. Liberibacter asiaticus' (Las) the most widespread. Phloem-limited bacteria such as liberibacters and phytoplas- mas are emerging as major pathogens of woody and herbaceous

Citrus greening or huanglongbing (HLB) is one of major devastating citrus diseases all over the world. This disease is caused by fastidious ?-proteobacterium, Candidatus liberibacter spp. and is transmitted by grafting as well as psyllids. Diaphorina citri or Trioza erytreae.
