Resistance to citrus canker induced by a variant of Xanthomonas citri ssp. citri is associated with a hypersensitive cell death response involving autophagy‐associated vacuolar processes [PDF]

open access: yesMolecular Plant Pathology, 2017
Xanthomonas citri ssp. citri (X. citri) is the causal agent of Asiatic citrus canker, a disease that seriously affects most commercially important Citrus species worldwide. We have identified previously a natural variant, X.

Analysis of Foci of Asiatic Citrus Canker in a Florida Citrus Orchard

Plant Disease, 1992
In October 1990, the occurrence of Asiatic citrus canker in an orchard in south Florida was apparently related to spread of Xanthomonas campestris pv. citri from dooryard trees 230 m away on an adjacent property. The establishment of apparent initial foci of disease in the orchard coincided temporally with a major rainstorm with high winds during mid ...

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

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.

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

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

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 ...
