Diversity of "Candidatus Liberibacter asiaticus," based on the omp gene sequence.
Huanglongbing (yellow dragon disease) is a destructive disease of citrus. The etiological agent is a noncultured, phloem-restricted alpha-proteobacterium, "Candidatus Liberibacter africanus" in Africa and "Candidatus Liberibacter asiaticus" in Asia. In this study, we used an omp-based PCR-restriction fragment length polymorphism (RFLP) approach to analyze the genetic variability of "Ca. Liberib...
متن کاملIncidence of Candidatus Liberibacter asiaticus infection in abandoned citrus occurring in proximity to commercially managed groves.
Huanglongbing is one of the most devastating diseases of citrus (Citrus spp.). One management tactic against huanglongbing is aggressive management of the vector, the Asian citrus psyllid (Diaphorina citri Kuwayama), with insecticide applications. However, D. citri in abandoned groves are not controlled and therefore pose a risk of reinfestation for nearby commercial citrus. These abandoned gro...
متن کاملContrasting amino acid profiles among permissive and non-permissive hosts of Candidatus Liberibacter asiaticus, putative causal agent of Huanglongbing
Huanglongbing is a devastating disease of citrus. In this study, a comprehensive profile of phloem sap amino acids (AA) in four permissive host plants of Candidatus Liberibacter asiaticus (CLas) and three non-permissive Rutaceae plants was conducted to gain a better understanding of host factors that may promote or suppress the bacterium. The AA profiles of Diaphorina citri nymphs and adults we...
متن کاملGenomic characterization of a liberibacter present in an ornamental rutaceous tree, Calodendrum capense, in the Western Cape Province of South Africa. Proposal of 'Candidatus Liberibacter africanus subsp. capensis'.
In 1994, the uncultured phloem-restricted bacteria of citrus huanglongbing (ex-greening) disease in Asia and Africa were characterized as 'Candidatus Liberobacter asiaticum' and 'Candidatus Liberobacter africanum', respectively. Following the rules of the International Code of Nomenclature of Bacteria, the two bacterial species have now been renamed 'Candidatus Liberibacter asiaticus' and 'Cand...
متن کاملThe Transcriptional Activator LdtR from ‘Candidatus Liberibacter asiaticus’ Mediates Osmotic Stress Tolerance
The causal agent of Huanglongbing disease, 'Candidatus Liberibacter asiaticus', is a non-culturable, gram negative, phloem-limited α-proteobacterium. Current methods to control the spread of this disease are still limited to the removal and destruction of infected trees. In this study, we identified and characterized a regulon from 'Ca. L. asiaticus' involved in cell wall remodeling, that conta...
