Comparative analysis for quantification of Citrus Variegated Chlorosis in the field [PDF]

Scientia Agricola, 2011
Citrus Variegated Chlorosis (CVC) caused by Xylella fastidiosa is one of the most important diseases for Brazilian citriculture. The CVC is a vascular disease with a long incubation period and symptoms similar to other disorders, and this factors ...

Prevalence, incidence and distribution of citrus variegated chlorosis in Bahia, Brazil [PDF]

Tropical Plant Pathology, 2008
Citrus variegated chlorosis (CVC) is one of the most important diseases for Brazilian citriculture. It is caused by Xylella fastidiosa subsp. pauca, a xylem limited, cycadelid and budwood transmitted bacterium. In Bahia, the second most important citrus region in Brazil, CVC has been present since 1997.

Cellular automata model for citrus variegated chlorosis

Physical Review E, 2000
A cellular automata model is proposed to analyze the progress of Citrus Variegated Chlorosis epidemics in S o Paulo oranges plantation. In this model epidemiological and environmental features, such as motility of sharpshooter vectors which perform L vy flights, hydric and nutritional level of plant stress and seasonal climatic effects, are included.

Nutritional deficiency in citrus with symptoms of citrus variegated chlorosis disease [PDF]

Brazilian Journal of Biology, 2009
It is well known that citrus plants that have been infected by Xylella fastidiosa display nutritional deficiencies, probably caused by production of extracellular polymers by the bacteria that block normal nutrient flow through the xylem. The aim of this

Gene disruption by homologous recombination in the Xylella fastidiosa citrus variegated chlorosis strain. [PDF]

Appl Environ Microbiol, 2002
ABSTRACT Mutagenesis by homologous recombination was evaluated in Xylella fastidiosa by using the bga gene, coding for β-galactosidase, as a model. Integration of replicative plasmids by homologous recombination between the cloned truncated copy of bga and ...

Transmission of Methylobacterium mesophilicum by Bucephalogonia xanthophis for paratransgenic control strategy of Citrus variegated chlorosis [PDF]

The Journal of Microbiology, 2009
Methylobacterium mesophilicum, originally isolated as an endophytic bacterium from citrus plants, was genetically transformed to express green fluorescent protein (GFP). The GFP-labeled strain of M. mesophilicum was inoculated into Catharanthus roseus (model plant) seedlings and further observed colonizing its xylem vessels.
