The family Closteroviridae revised
TLDR
The mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine), and the family now comprises three genera. Expand
IDENTIFICATION OF DNA SEQUENCES RELATED TO XYLELLA FASTIDIOSA IN OLEANDER, ALMOND AND OLIVE TREES EXHIBITING LEAF SCORCH SYMPTOMS IN APULIA (SOUTHERN ITALY)
TLDR
Molecular tests extended to almond and oleander trees with leaf scorching symptoms, growing next to diseased olive orchards, were positive for X. fastidiosa, and studies aimed at isolating the bacterium, determining the strain, evaluating its pathogenicity, and identifying the putative local vector are currently in progress. Expand
Infectivity and Transmission of Xylella fastidiosa by Philaenus spumarius (Hemiptera: Aphrophoridae) in Apulia, Italy
TLDR
The discovery of Xylella fastidiosa from olive trees with “Olive quick decline syndrome” in October 2013 on the west coast of the Salento Peninsula prompted an immediate search for insect vectors of the bacterium, and transmission tests showed P. spumarius as a vector of X. fastidioa strain infecting olives trees in theSalento Peninsula, Italy. Expand
DETECTION OF XYLELLA FASTIDIOSA IN OLIVE TREES BY MOLECULAR AND SEROLOGICAL METHODS
TLDR
The identification of X. fastidiosa in OQDS-affected trees represents the first confirmed detection of this bacterium in the European Union (EU), but its exact role in the aetiology of this disease is yet to be determined. Expand
ISOLATION OF A XYLELLA FASTIDIOSA STRAIN INFECTING OLIVE AND OLEANDER IN APULIA, ITALY
TLDR
The isolation in pure culture of the Xylella fastidiosa strain associated with the quick decline syndrome of olive was attempted from symptomatic, naturally infected olive and oleander plants, and a periwinkle seedling that had been exposed to, and was infected by Xyleella-positive spittlebugs. Expand
Characterization of the Sweet Cherry Isolate of Plum Pox Potyvirus.
TLDR
An isolate of plum pox potyvirus from sweet cherry (PPV-SwC) in southern Italy was investigated and it was confirmed that the isolate lacks AluI and RsaI sites in the C-terminal region of the coat protein (CP) gene. Expand
Production and characterization of a monoclonal antibody specific to the M serotype of plum pox potyvirus
TLDR
A monoclonal antibody to an Albanian isolate of plum pox potyvirus (PPV) was obtained, that specifically recognized strain M of this virus, and is an useful addition to the panel of PPV-specific MAbs available to date. Expand
Genome-Wide Analysis Provides Evidence on the Genetic Relatedness of the Emergent Xylella fastidiosa Genotype in Italy to Isolates from Central America.
TLDR
A comparative analysis based on single nucleotide polymorphisms and the study of the pan-genome of the 27 currently public available whole genome sequences of X. fastidiosa found the clustering and distinctiveness of the ST53 isolates supports the hypothesis of their common origin, and the limited genetic diversity among these isolates suggests this is an emerging clade within subsp. Expand
Production of a monoclonal antibody specific to the El Amar strain of plum pox virus.
TLDR
There is now available a set of monoclonal antibodies which are highly specific to the four currently known groups of PPV strains, supporting the hypothesis of an additional specific PPV group. Expand
Xylella fastidiosa in Olive in Apulia: Where We Stand.
TLDR
Preliminary evidence of the presence of resistance in some olive cultivars represents a promising approach currently under investigation for long-term management strategies, and the present review describes the current status of the epidemic and major research achievements since 2013. Expand
