Grapevine yellows (GY) are diseases of Vitis vinifera caused by phytoplasmas. On the basis DNA analysis, it is possible to distinguish different groups and subgroups among grapevine Flavescence doree (FD), most serious problem in European vineyards, a phytoplasma which belongs elm group (EY or 16SrV), Differences between 7 isolates this group, found until now French, Italian German grapevines, 4 phytoplasmas same isolated mainly from alder Europe America, were investigated. These 11 EY-group...
A survey was conducted over several years in Italy and the Balkans order to gain an understanding of relationship between Flavescence dorée (FD) phytoplasma isolates found clematis grapevine. total 399 107 grapevine samples were analyzed. The results showed that 36% Clematis vitalba plant infected by phytoplasmas which, grapevine, are associated with FD, a quarantine disease Europe. Infected plants also areas where FD had never previously been reported infect such as Macedonia, Croatia some...
Background and Aims: Chitosan, a chitin deacetylated derivative, is biopolymer able to elicit the plant defence machinery against variety of pathogens. In crop protection, it successfully employed for its low toxicity, mainly virus diseases. this study, efficacy new chitosan formulation (Kendal Cops® (Kc)) was evaluated in grapevine powdery mildew infection. Total polyphenol (TP) content antiradical power different grape tissues experimental wines produced from treated grapes were also...
Interaction between phytoplasma and grapevine at the physiological level is still poorly understood, as are plant defence mechanisms against pathogen. This study investigates of gene expression three selected genes in a large number plants belonging to six disease/cultivar groups (healthy Chardonnay, Bois noir‐infected Flavescence dorée‐infected Barbera Prosecco, recovered Prosecco). All were grown vineyards uncontrolled conditions order represent physiology disease accurately possible....
In order to devise a procedure be used as reference for detection of grapevine phytoplasmas and monitoring Flavescence doree, 12 combinations comprising three methods plant DNA extraction 4 procedures amplification in polymerase chain reaction phytoplasma were examined parallel using the same tissues infected with phytoplasmas. first series periwinkles ( Catharanthus roseus ) isolates Elm yellows group (16SrV) maintained greenhouse, used. second grapevines Vitis vinifera naturally doree or...
Heteroduplex mobility assay (HMA) and DNA sequencing were performed on Flavescence dorée (FD) phytoplasma strains related phytoplasmas belonging to the elm yellows group. Part of ribosomal RNA gene operon a nonribosomal region utilized for phylogenetic analyses. Two FD strains, FD92 FD‐D, detected in France Italy, respectively, identical both fragments, confirming previous results. Other all very similar most closely resembled ALY, an Italian alder phytoplasma. Phytoplasmas associated with...
Abstract Grapevine leafroll‐associated virus 2 (GLRaV‐2) was detected by serological and molecular analyses in several grapevine accessions of different varieties from Italian, Greek, French Brazilian vineyards a 2001–2002 survey. In order to study the genetic variability among GLRaV‐2 isolates open reading frame (ORF) coding coat protein (CP), heteroduplex mobility assays were performed on 17 six strains used as reference. Eight diverse variants identified infected grapevines tested. The...
After having schematically drawn attention to the distribution of cyto-chrome oxidase in cochlea normal guinea-pig (described a former work) and principal data literature relating histoche-mical biochemical variations shown inner ear subsequent sound stimulation, authors describe method investigation its results. Intense stimulation (100 decibels) with pure tones diverse frequencies (250, 2000, 4000, 8000 Hz), for period 3 hours, brings about histochemically demonstrable reduction enzymatic...
A study was performed between 2005 and 2007 to identify the presence of any phytoplasmas that normally infect grapevines in Italy (16SrV-C, 16SrV-D 16SrXII-A) wild plants vicinity vineyards. This survey included sampling from Cornus sanguinea (36 plants) Sambucus nigra (32 collected hedges close vineyards north-eastern Italy. The majority these were showing typical phytoplasma disease symptoms, such as yellowing, reddening, leaf-roll witches’ broom. Total nucleic acids extracted leaf veins...
