A new inclusive MLVA assay to investigate genetic variability of Xylella fastidiosa with a specific focus on the Apulian outbreak in Italy
The Olive Quick Decline Syndrome by Xylella fastidiosa subspecies pauca is among the most severe phytopathological emergencies nowadays. In few years, the outbreak devastated olive groves in Apul...
Assessment of the genetic diversity among strains of Xanthomonas cynarae by randomly amplified polymorphic DNA analysis and development of specific characterized amplified regions for the rapid identification of X-cynarae
The randomly amplified polymorphic DNA (RAPD) method was used to investigate the genetic diversity in Xanthomonas cynarae, which causes bacterial bract spot disease of artichoke. This RAPD analysis...
BREEDING, GENETIC AND GENOMIC OF CITRUS FOR DISEASE RESISTANCE
Although the citriculture is one of the most important economic activities in Brazil, it is based on a small number of varieties. This fact has contributed for the vulnerability of the culture rega...
Citrus genomics
Citrus fruits (sweet orange, mandarin, pummelo, grapefruit, lemon, lime and assorted hybrids) are among the most widely grown and economically important fruit tree crops in the world. As fresh frui...
Combined use of a new SNP-based assay and multilocus SSR markers to assess genetic diversity of Xylella fastidiosa subsp pauca infecting citrus and coffee plants
Two haplotypes of Xylella fastidiosa subsp. pauca (Xfp) that correlated with their host of origin were identified in a collection of 90 isolates infecting citrus and coffee plants in Brazil, based ...
Comparative dispersal of Homalodisca coagulata and Homalodisca liturata (Homoptera : Cicadellidae)
California's viticulture and ornamental industries have suffered significant losses since the introduction of Homalodisca coagulata (Say), an important vector of the Pierce's disease bacterium. A b...
Differentiation of "Candidatus Liberibacter asiaticus" Isolates by Variable-Number Tandem-Repeat Analysis
Four highly polymorphic simple sequence repeat (SSR) loci were selected and used to differentiate 84 Japanese isolates of "Candidatus Liberibacter asiaticus." The Nei's measure of genetic diversity...
Evaluation of Xylella fastidiosa genetic diversity by fAFLP markers
The first phytopathogenic bacterium with its DNA entirely sequenced is being detected and isolated from different host plants in several geographic regions. Although it causes diseases in cultures ...
Evolution of the response of segregating populations of plums and the association with microsatellite markers of leaf scald
The evolution of leaf scald (Xylella fastidiosa) resistance was evaluated in individuals of seven plum segregating populations, consisted of seedling progenies originating from crosses involving ni...
H-1-NMR Metabolite Fingerprinting Analysis Reveals a Disease Biomarker and a Field Treatment Response in Xylella fastidiosa subsp. pauca-Infected Olive Trees
Xylella fastidiosa subsp. pauca is a xylem-limited bacterial phytopathogen currently found associated on many hectares with the olive quick decline syndrome in the Apulia region (Southern Italy), a...
HecA, a member of a class of adhesins produced by diverse pathogenic bacteria, contributes to the attachment,, aggregation, epidermal cell killing, and virulence phenotypes of Erwinia chrysanthemi EC16 on Nicotiana clevelandii seedlings
Erwinia chrysanthemi is representative of a broad class of bacterial pathogens that are capable of inducing necrosis in plants. The E. chrysanthemi EC16 hecA gene predicts a 3,850-aa member of the ...
Multilocus simple sequence repeat markers for differentiating strains and evaluating genetic diversity of Xylella fastidiosa
A genome-wide search was performed to identify simple sequence repeat (SSR) loci among the available sequence databases from four strains of Xylella fastidiosa (strains causing Pierce's disease, ci...
