Rapid Identification of a Second Outbreak of Asiatic Citrus Canker in the Northern Territory Using the Polymerase Chain Reaction and Genomic Fingerprinting.

Australasian Plant Pathology, 1995
In May 1993, symptoms of asiatic citrus canker were found on West Indian lime, lemon and grapefruit trees in a mixed citrus orchard at Lambell’s Lagoon, near Darwin, Northern Territory, close to the site of a previous (1991) canker outbreak. Symptoms occurred on the spring growth flush at the start of the wet season (October 1992). The time lag between

Bacterial Exudation from Lesions of Asiatic Citrus Canker and Citrus Bacterial Spot

Plant Disease, 1991
When water was added to wells surrounding young lesions of Asiatic citrus canker (caused by Xanthomonas campestris pv. citri) on detached, field-collected leaves of grapefruit, about 10 4 -10 5 bacteria per milliliter were exuded immediately. Bacterial exudation into the water continued at high levels for 24 hr, and cumulative release ranged from 10 5

Effect of citrus leaf-miner damage, mechanical damage and inoculum concentration on severity of symptoms of Asiatic citrus canker in Tahiti lime

Crop Protection, 2007
Abstract Citriculture in Sao Paulo State, Brazil, is threatened by Asiatic citrus canker (Xanthomonas axonopodis pv. citri). The introduction of the Asian citrus leaf miner (Phyllocnistis citrella [CLM]) has resulted in an increase in the number of disease foci and has changed the spatial pattern of citrus canker symptomatic trees from strong ...

First Report of Xanthomonas citri pv. citri Pathotype A Causing Asiatic Citrus Canker in Madagascar [PDF]

Plant Disease
Asiatic citrus canker (ACC), caused by Xanthomonas citri pv. citri, is a threat to citrus industries worldwide. X. citri pv. citri is delineated into three pathotypes differing in pathogenicity towards Citrus species and hybrids. The pathogen negatively impacts production in tropical and subtropical areas, resulting in direct losses (yield decrease due

A PCR-based assay for differentiating A- and A*-type strains of Xanthomonas citri subsp. citri, the causal agent of Asiatic citrus canker

Journal of General Plant Pathology, 2013
By applying A- and A*-type strains of Xanthomonas citri subsp. citri (Xcc) in a repetitive sequence-based polymerase chain reaction (rep-PCR), two DNA amplicons, one unique to each strain, were evaluated as a probe against the DNA of Xcc strains. Two pairs of primers derived from these amplicons were tested in a PCR analysis. The results confirmed that

Asiatic Citrus Canker Detected in a Pummelo Orchard in Northern Australia

Plant Disease, 1992
Raised, roughly circular, corky scabs 4-5 mm in diameter and typical of citrus canker were observed on spring flush leaves, twigs, and fruits of pummelos (Citrus grandis) in a young orchard near Darwin, Australia, during a survey conducted in 1991 as part of the Northern Australia Quarantine Strategy.

The Effect of Irrigation Practices on the Spatio-temporal Increase of Asiatic Citrus Canker in Simulated Nursery Plots in Reunion Island

European Journal of Plant Pathology, 1999
Asiatic citrus canker is a potentially severe disease of several citrus species and cultivars in many tropical and subtropical areas. In such areas, infected nursery plants constitute an important source of primary inoculum for newly established citrus groves.

Re-occurrence of Asiatic citrus canker in the Makkah Province of Saudi Arabia and characterization of the causal agent Xanthomonas citri pv. citri isolated from Mexican lime

Journal of Plant Pathology, 2023
Asiatic citrus canker (ACC) caused by Xanthomonas citri pv. citri (Xcc) is a destructive disease of citrus crops, worldwide. Typical ACC symptoms were observed on Mexican lime trees in the Makkah Province, Saudi Arabia, where the disease had been thought to be eradicated after its first occurrence in the late 1980ies.

A standard area diagram set to aid estimation of the severity of Asiatic citrus canker on ripe sweet orange fruit

European Journal of Plant Pathology, 2014
Asiatic citrus canker (ACC) is a major disease of citrus in many tropical and subtropical citrus-growing regions. Severe disease can develop on the fruit, making it unmarketable. Research activities need accurate and reliable methods to estimate the severity of citrus canker, most often done visually by raters. The objective was to validate and compare

Sample Preparation for Secretome Analysis in A*-Type Strains of Xanthomonas citri subsp. citri, the Causal Agent of Asiatic Citrus Canker Disease

2012
Xanthomonas citri subsp citri (Xcc) is responsible for one of the most destructive diseases of citrus fruits, Asiatic citrus canker. Based on the bacterial host range, the pathogenic forms, A, A*, and Aw have been identified. A*-type strains are not well characterized and they have been reported to differ from other A-type strains on the basis of ...
