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 plant pathogens mostly transmitted by psyllids. The genus was originally spelled Liberobacter.[1]
Species
Named species include:[2]
- Liberibacter africanus originated in Africa and is a causal agent of citrus greening disease, also known as huanglongbing, and vectored by the African citrus psyllid Trioza erytreae.[3]
- Liberibacter americanus is a novel species from Brazil described in 2005 and associated with huanglongbing and vectored by the Asian citrus psyllid Diaphorina citri.[4]
- Liberibacter asiaticus originated in Asia and is a causal agent of huanglongbing, vectored by the Asian citrus psyllid D. citri.[5]
- Liberibacter crescens[6] was isolated from papaya growing in Puerto Rico.
- Liberibacter europaeus is a novel species described in 2010, found in pear trees, where it seems to cause no symptoms and is vectored by the psyllid, Cacopsylla pyri.[7]
- Liberibacter psyllaurous is a novel species described in 2008 from solanaceous host plants potato and tomato and vectored by the potato tomato psyllid Bactericera cockerelli.[8] L. psyllaurous plays a dual role as a plant pathogen and as an inherited bacterial endosymbiont. This symbiont modifies tomato defenses in favor of itself and its psyllid vector.[9]
- Liberibacter solanacearum[10] is a causal agent of zebra chip disease in potatoes and vectored by the potato tomato psyllid Bactericera cockerelli.[11] There are five haplotypes described within this species, designated LsoA and LsoB (from solanaceous plants in North America), and LsoC, LsoD, and LsoE (from carrots and celery in Europe).[12][13] L. psyllaurous is a synonym for L. solanacearum haplotype A[14] (identical 16S rRNA genes).
- Liberibacter brunswickensis[15] associated with the psyllid Acizzia solanicola on eggplant in Australia.
