RAPD profile and antibiotic susceptibility of Xylella fastidiosa, causal agent of citrus variegated chlorosis

Letters in Applied Microbiology, 2001
The aim of this study was to evaluate the diversity of Xylella fastidiosa isolated from citrus trees affected by Citrus Variegated Chlorosis (CVC).The antibiotic susceptibility by agar disc diffusion and minimum inhibitory concentration (MIC) methods was observed for all drug evaluated, except for penicillin-G.

Diversity of a Xylella fastidiosa Population Isolated from Citrus sinensis Affected by Citrus Variegated Chlorosis in Brazil

Systematic and Applied Microbiology, 1998
Summary Diversity of a population of Xylella fastidiosa isolated from sweet orange plants showing citrus variegated chlorosis (CVC) symptoms was assessed by PCR-based techniques. Thirty-seven strains were isolated throughout the 1997 year in the orange belt of Sao Paulo State, Brazil. Strains isolated from coffee, grape, oleander and plum were also

Inoculum reduction and vector control on the temporal progress of citrus variegated chlorosis incidence

Pest Management Science, 2021
AbstractBACKGROUNDCitrus variegated chlorosis (CVC) is an important citrus disease caused by the sharpshooter‐transmitted bacterium Xylella fastidiosa subsp. pauca. Information about the efficacy of its disease management is bounded to either inoculum reduction or vector control.

Navelina ISA 315: A cultivar resistant to citrus variegated chlorosis

Crop Protection, 2014
Citrus variegated chlorosis (CVC), caused by Xylella fastidiosa, is a bacterial disease of great importance to the Brazilian citrus industry. CVC is transmitted by grafting and by leafhoppers of the Cicadellidae and Cercopidae families. There is little information about CVC tolerant sweet orange cultivars (Citrus sinensis L. Osbeck).

The effect of irrigation on development of citrus variegated chlorosis symptoms

Crop Protection, 2014
Abstract The incidence and severity of citrus variegated chlorosis (CVC) caused by Xylella fastidiosa are higher in the northern region of Sao Paulo, Brazil than in the southern region. This phenomenon is partly due to differences in the climate, especially rainfall, as the northern region tends to be drier than the southern region. The progress of

Insertional Transposon Mutagenesis in the Xylella fastidiosa Citrus Variegated Chlorosis Strain with Transposome

Current Microbiology, 2004
To overcome the difficulty in obtaining mutants of the citrus strains of Xylella fastidiosa, we evaluated mutagenesis using the transposome system as a tool for the isolation of a large number of mutants. Electroporation of a commercial transposome system in X.

Citrus Variegated Chlorosis: an Overview of 30 Years of Research and Disease Management

Tropical Plant Pathology, 2020
The emergence of citrus variegated chlorosis (CVC) disease had dramatic consequences to the citrus industry in Brazil. First reported in Sao Paulo State in 1987, this disease affected approximately 100 million sweet orange trees in the region 20 years later.

Genetic Diversity of Xylella fastidiosa Associated with Citrus Variegated Chlorosis in Brazil

2001
Xylella fastidiosa Wells et al. (4) causes diseases of economic importance in several cultivated plants. In Brazil, X. fastidiosa has been associated with citrus variegated chlorosis (CVC) on sweet oranges (Citrus sinensis (L.) Osb.) and a dieback and leaf scorch type of disease on coffee (Coffea spp.).

SURVEY OF XYLELLA FASTIDIOSA AND CITRUS VARIEGATED CHLOROSIS IN SÃO PAULO STATE, BRAZIL

Journal of Plant Pathology, 2013
Contrary to the well-documented incidence and severity of Citrus variegated chlorosis (CVC) throughout the sweet orange groves of Sao Paulo state (Brazil), the incidence and distribution of its causal agent, Xylella fastidiosa, is not well known.

Citrus Functional Genomics and Molecular Modeling in Relation to Citrus sinensis (Sweet Orange) Infection with Xylella fastidiosa (Citrus Variegated Chlorosis)

OMICS: A Journal of Integrative Biology, 2016
Citrus are among the economically most important fruit tree crops in the world. Citrus variegated chlorosis (CVC), caused by Xylella fastidiosa infection, is a serious disease limiting citrus production at a global scale. With availability of citrus genomic resources, it is now possible to compare citrus expressed sequence tag (EST) data sets and ...
