Control of huanglongbing (HLB), a destructive disease of citrus that represents a major threat to the world citrus industry, is preventive and largely based on inoculum elimination by removal of infected trees and chemical treatments against vectors.
The phloem-limited bacterium of greening disease of citrus is a member of the alpha subdivision of the Proteobacteria.

Comparisons with sequences of 16S rDNAs obtained from the GenBank data base revealed that the two citrus greening disease BLOs belong to the alpha subdivision of the class Proteobacteria, and it is proposed that this new group of bacteria is called "liberobacter".
The genome sequence of the plant pathogen Xylella fastidiosa
The complete genome sequence of X. fastidiosa clone 9a5c is reported, providing direct evidence of phage-mediated horizontal gene transfer and indicating that the molecular basis for bacterial pathogenicity is both conserved and independent of host.
PCR detection of the two 'Candidatus' Liberobacter species associated with greening disease of citrus.
A PCR method to detect the two liberobacter species in citrus trees by amplification of a 1160 bp fragment of their 16S rDNA is described.
Detection and identification of the two Candidatus Liberobacter species associated with citrus huanglongbing by PCR amplification of ribosomal protein genes of the beta operon.
A new PCR detection method based on the amplification of ribosomal protein genes which allows direct identification of the liberobacter species by the size of the amplified DNA.
'Candidatus Liberibacter americanus', associated with citrus huanglongbing (greening disease) in São Paulo State, Brazil.
Results confirm that the SPS-HLB liberibacter is a novel species for which the name 'Candidatus Liberibacter americanus' is proposed, and like the African and the Asian liberibacters, the 'American' liberibacteria is restricted to the sieve tubes of the citrus host.

Two uncultured phloem-restricted bacteria of citrus huanglongbing (ex-greening) disease in Asia and Africa are renamed and a third liberibacter was detected by PCR in an ornamental rutaceous tree, Cape chestnut (Calodendrum capense), in South Africa.
A phytoplasma closely related to the pigeon pea witches'-broom phytoplasma (16Sr IX) is associated with citrus huanglongbing symptoms in the state of São Paulo, Brazil.
Results show that a phytoplasma of group IX is associated with citrus HLB symptoms in northern, central, and southern SPs, transmitted to citrus from an external source of inoculum, but the putative insect vector is not yet known.

A xylem-limited bacterium resemblingXylella fastidiosa has been shown previously by electron mmcroscopy to be associated with citrus variegated chlorosis (CVC), a new disease of sweet organe tress in Brazil and ELISA indicates that the CVC bacterium is a strain ofX.
