Cross‐reactive Antigens between Xanthomonas campestris pv. citri Pathotypes and Citrus Species

Journal of Phytopathology, 1993
AbstractCross‐reactive antigens were detected in crude and semi‐purified preparations from acetone powder of Citrus aurantifolia and Citrus sinensis leaves with antisera to Xanthomonas campestris pv. citri pathotypes A and C by DAS‐ELISA. Antiserum to X. campestris pv. citri pathotype C revealed an antigenic disparity between C.

A simple method for maintaining Xanthomonas campestris pv. citri.

Zhonghua Minguo wei sheng wu ji mian yi xue za zhi = Chinese journal of microbiology and immunology, 1990
A typical colony of each of strains XW17, XW45, XW47, XW82, XW86, XW118, and XW138 of Xanthomonas campestris pv. citri was streaked onto nutrient agar, GY agar, minimal agar, and semi-enriched minimal agar plates, respectively. The agar plates, after incubated at 30 degrees C for 2-4 days, were inverted and stored at 4 degrees C in darkness. All of the

Phage-Induced Mutations of Histidine and Cysteine Syntheses in Xanthomonas Campestris Pv. Citri

1987
Filamentous phage Cfl6, in addition to inducing mutation of cysteine synthesis in strain XW47 of Xanthomonas campestris pv. citri probably by integration of its prophage at the affected genes (21), also induced mutations in other strains of this bacterium.

Purification and partial characterization of an agglutinin in citrus leaves against extracellular polysaccharides of Xanthomonas campestris pv. citri

Physiological Plant Pathology, 1985
Abstract An agglutinin against extracellular polysaccharides (EPS) of Xanthomonas campestris pv. citri, the casual agent of citrus canker, was precipitated with 50% saturated ammonium sulphate from an acid (pH 4·0) homogenate of citrus leaf tips. The agglutinin was selectively withdrawn from the crude preparation at pH 4·0 by agglutination with the ...

Differential stability of filamentous phage genomes in Xanthomonas campestris pv citri.

Microbios, 1989
Stability of carrier state in filamentous phage-infected Xanthomonas campestris pv citri varied drastically even for closely related phage types. The spontaneous curing frequency for cells infected with Cf16-12, Cf16, Cf16-v1 and Cf was 1, 5, 96 and 100%, respectively. The size of the phage replicative-form (RF) pool which built up rapidly at the onset

Caractérisation de nouvelles souches atypiques de Xanthomonas campestris pv. citri [PDF]

, 1993
Le chancre bactérien des agrumes a été mis en évidence en Arabie saoudite et à Oman. Les souches de Xanthomonas campestris pv. citri ont été isolées puis inoculées à l'hôte d'origine : le limettier mexicain. Les lésions étaient similaires à celles provoquées par X. c. pv. citri pathotype A.

Detection of Xanthomonas campestris pv. citrumelo and X. citri from Citrus Using Membrane Entrapment Immunofluorescence

Plant Disease, 1990
Xanthomonas campestris pv. citrumelo (formerly X. campestris pv. citri strain E), the causal agent of citrus bacterial spot, and X. citri (formerly X. campestris pv. citri strain A), the causal agent of citrus bacterial canker, were easily detected in leaf extracts from symptomatic and asymptomatic citrus leaves and from cultures by immunofluorescence ...

Plasmid-Based Hybridization Probes for Detection and Identification ofXanthomonas campestrispv.citri

Plant Disease, 1992
Two hybridization probes were developed from plasmid DNA of pathotype A strain XC62 of Xanthomonas campestris pv. citri. Plasmid pFL62.42 was constructed by cloning a 4.2-kb BamHI fragment of an indigenous plasmid of strain XC62 in the vector pUC9. Plasmid pFL1 contains an internal 700-bp EcoRI fragment from pFL62.42; this fragment was also cloned in ...

Identification and nucleotide sequence of attachment site of the Cflt filamentous phage from Xanthomonas campestris pv. citri.

Zhonghua Minguo wei sheng wu ji mian yi xue za zhi = Chinese journal of microbiology and immunology, 1990
It has been reported that the attachment site on the phage attP is located from 69.2 to 73.8 min on Cflt RF DNA. KpnI and PstI were used, which cut respectively at 67.2 and 72.6 min of Cflt RF DNA. A 0.54 kb fragment containing attP was obtained. For isolation of the right (attR) and left (attL) junctions of prophage and host chromosomal DNA, lysogen ...
