Grapevine Trunk Diseases in British Columbia: Incidence and Characterization of the Fungal Pathogens Associated with Esca and Petri Diseases of Grapevine [PDF]

Plant Disease, 2014
Esca and Petri disease are two economically important grapevine diseases worldwide. This study reports for the first time the occurrence of both diseases on grapevines in British Columbia (BC) and subsequently in Canada. Visual assessment of 55,699 vines in 118 vineyards revealed a low incidence of esca with only 104 (0.2%) vines showing foliar ...

Contribution for a better understanding of grapevine fungal trunk diseases in the Portuguese Dão wine region

Phytopathologia Mediterranea, 2012
Summary. Esca and Petri disease, two of the most important fungal trunk diseases of grapevine, are responsible for significant losses by causing premature decline and dieback in vineyards worldwide. The Portuguese Dão wine region is no exception.

Characteristics of the Seed Germination and Seedlings of Six Grape Varieties (V. vinifera)

Plants, 2022
Intraspecific recurrent selection in V. vinifera is an effective method for breeding of high quality, disease-, cold-, and drought-resistance grapes. Exploring the optimal treatment methods for grape (V. vinifera) seeds can help to accelerate the process

Enhancing grapevine viability and pathogen control through optimised hot water treatment

OENO One
Petri disease is a Grapevine Trunk Disease (GTD) primarily associated with the ascomycete species Phaeomoniella chlamydospora, which leads to substantial losses in young vineyards, particularly during the first years after planting.

Aerial inoculum patterns of Petri disease pathogens in South African vineyards and rootstock mother blocks

Phytopathologia Mediterranea, 2020
Petri disease is caused by the xylem inhabiting fungi Phaeomoniella (Pa.) chlamydospora and several Phaeoacremonium (Pm.) species. Pruning wounds are known host ports of entry for aerial spores of these pathogens.

Evaluation of biocontrol agents for grapevine pruning wound protection against trunk pathogen infection.

Phytopathologia Mediterranea, 2011
Trunk diseases of grapevine are caused by numerous pathogens, including Eutypa lata, Phaeomoniella chlamydospora, and species of Botryosphaeriaceae (incl. Botryosphaeria and aggregate genera), Phomopsis and Phaeoacremonium.

First Report of Phaeoacremonium mortoniae Causing Petri Disease of Grapevine in Spain

Plant Disease, 2007
In May 2006, symptoms of grapevine decline were observed on 4-year-old grapevines (cv. Cabernet Sauvignon) grafted onto 110 R rootstock in Daimiel (Ciudad Real Province, central Spain). Affected vines had low vigor, reduced foliage, and chlorotic leaves. Cross or longitudinal sections of the rootstock trunk showed black spots and dark streaking of the

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

First Report of Phaeoacremonium parasiticum Causing Petri Disease of Grapevine in Peru

Plant Disease, 2009
Since 2005, symptoms of grapevine decline have been observed on 4- to 8-month-old grapevines (cvs. Red globe and Crimson) grafted onto 1103 P rootstock in Ica and Pisco valleys in southern Peru. Affected plants exhibited weak growth, interveinal chlorosis, necrosis and wilting of leaves, and death.
