The draft whole-genome sequence of "Candidatus Liberibacter solanacearum" strain R1, isolated from and maintained in tomato plants in California, is reported. The R1 strain has the genome size of 1,204,257 bp, G+C content of 35.3%, 1,101 predicted open reading frames, and 57 RNA genes.

The draft genome sequence of "Candidatus Liberibacter asiaticus" strain A4, isolated from a mandarin citrus in Guangdong, People's Republic of China, is reported. The A4 strain has a genome size of 1,208,625 bp, G+C content of 36.4%, 1,107 predicted open reading frames, and 53 RNA genes.

The psyllid Trioza apicalis Förster (Hemiptera: Triozidae) is a serious pest of carrots, Daucus carota L., in Europe. Carrots exhibiting symptoms of psyllid damage were observed in commercial fields in southern Finland in 2008. Symptoms in affected plants included leaf curling, yellow and purple discoloration of leaves, stunted growth of shoots and roots, and proliferation of secondary roots. M...

The Asian citrus psyllid (Diaphorina citri Kuwayama) is the principal vector of ‘Candidatus Liberibacter asiaticus’ (CLas) associated with huanglongbing (HLB), the most serious citrus disease worldwide. New control measures including pesticides are urgently needed to combat HLB, especially to protect young or newly planted citrus trees from CLas-inoculation by vector psyllids. Here, we tested C...

El cultivo de papa representa en nuestro país una fuente divisas y genera gran cantidad empleos. Hasta la fecha no existe un estudio formal sobre fluctuación poblacional Bactericera cockerelli Candidatus liberibacter. Este se realizó con el propósito determinar dinámica incidencia liberibacter papa, cual llevó a cabo los municipios Jinotega, La Concordia, San Rafael del Norte Yalí, departamento...

Candidatus Liberibacter asiaticus (CLas) is a phloem-limited bacterium transmitted by the Asian citrus psyllid, Diaphorina citri, and the presumptive causal agent of citrus greening disease. The current method of detection for CLas within plant and insect samples is by a presence/absence qPCR assay using the CLas 16S rDNA gene target. Although qPCR is highly sensitive, low bacterial titers or s...

‘Candidatus Liberibacter’ species are phloem-limited prokaryotes that are associated with citrus huanglongbing (HLB), zebra chip (ZC) disease, diseases of other solanaceous crops, and carrot psyllid damage. Citrus HLB (also referred to as greening and yellow shoot disease), potato ZC and diseases of other solanaceous crops are unique and possibly recently emerged hostpathogen(s)-insect vector p...
