Evaluation of Greek grapevine cultivars for resistance to Phaeomoniella chlamydospora

European Journal of Plant Pathology, 2017
In the present study, four Greek (Agiorgitiko, Asyrtiko, Roditis and Xinomavro) and one international (Soultanina) grapevine cultivars (Vitis vinifera L.) were screened for their resistance to Phaeomoniella chlamydospora. Artificial inoculation was carried out by drilling a hole into the trunk and injecting a concentrated conidial suspension into the ...

A method to detect and quantify Phaeomoniella chlamydospora and Phaeoacremonium aleophilum DNA in grapevine-wood samples

Applied Microbiology and Biotechnology, 2013
Grapevines are sensitive to a wide range of fungal pathogens, including agents such as Phaeomoniella chlamydospora and Phaeoacremonium aleophilum that cause tracheomycosis. In the present study, a procedure for DNA extraction from grapevine woody tissue is first evaluated and shown to be suitable for quantitative analysis.

Genetic diversity among isolates ofPhaeomoniella chlamydosporaon grapevines

Australasian Plant Pathology, 2006
Phaeomoniella chlamydospora is one of the main causal agents of Petri disease and esca of grapevines. Although it is known to have a coelomycete synanamorph, no teleomorph has thus far been reported for P. chlamydospora, and its disease cycle remains largely unknown. The present study compared the genetic diversity of P.

Development of microsatellite markers for the grapevine fungal pathogen Phaeomoniella chlamydospora

Molecular Ecology Resources, 2008
AbstractTwenty polymorphic microsatellite markers from microsatellite‐enriched genomic DNA of the grapevine fungal pathogen, Phaeomoniella chlamydospora, were developed and characterized. The markers were used to genotype isolates from Australia and from Europe/Eurasia. The number of alleles per locus ranged from two to 11.

Investigation on the occurrence of Phaeomoniella chlamydospora in canes of rootstock mother vines

Australasian Plant Pathology, 2002
The presence of Phaeomoniella chlamydospora and Phaeoacremonium spp., the causal organisms of Petri disease of grapevine, in canes of rootstock vines in four mother blocks was determined monthly by means of isolations from the basal and fourth internodes.

Effect of Phaeomoniella chlamydospora and Phaeoacremonium sp. on in vitro grapevine plants

Scientia Horticulturae, 2008
Artificial inoculation with fungal species involved in the Petri disease was performed on in vitro grapevine shoots. After 2 months, plantlets were observed and the presence of any leaf chlorosis or necrosis, considered as symptoms of the disease, were recorded.
