Esca disease of grapevine is gaining increasing importance in Central European wine-growing countries. Several fungi, all of which are wood-inhabiting, were found to be associated with the disease. The taxa thought to act as main causal agents are the basidiomycete, Fomitiporia mediterranea, and, less frequently, the deuteromycetes, Phaeomoniella chlamydospora and Phaeoacremonium aleophilum. In...

Fomitiporia mediterranea M. Fisch. (Fmed) is a basidiomycete first described in 2002, and was considered up to then as part of punctata (P. Karst) Murrill. This fungus can degrade lignocellulosic biomass, causing white rot leaving bleached fibrous host residues. In Europe Fmed the main grapevine wood (Esca) agent within Esca disease complex, which includes some most economically important Grape...

During last decade, the decline of elm trees was observed in Fars province (Iran) due to a wood decaying agent in heartwood of the trees. Unknown basidiomycete isolates were frequently isolated from such trees. The objective of the present study was to identify the basidiomycete isolates by molecular phylogenetic analysis of the internal transcribed spacers of ribosomal DNA. For this purpose, i...

Many fungal pathogens are associated with grapevine trunk diseases (GTDs), which cause important yield and economic losses in grape production. There no effective control methods against GTDs once plants infected, so research is aimed at preventive measures to avoid infections nurseries vineyards. Inhibitory activities of the phenolic compounds eugenol, epigallocatechin–3–O–gallate (EGCG) thymo...

Grapevine (Vitis vinifera L.) is one of the most prevalent and long-standing cultivated crops in world due to its non-selective climate soil demands, types usage having a wide range varieties. Turkey has rich grapevine gene pool because favorable zone. Viticulture, which an important role agriculture, faces many problems process production marketing. Fungal diseases take place by limiting where...

one of the most important and elusive diseases of grapevine is esca disease. esca is a complex disease that comprises a combination of symptoms caused by various fungi including growth retardation, decrease in productivity and decline of the plant and usually affecting adult plants (8 to 10 years and older). the purpose of this research was to study the genetic variations of fungal agents assoc...

Physiological features were examined of a 20-year-old Vitis vinifera ‘Italia’ table grape vineyard cropped in Apulia, Italy. Healthy vines with no foliar symptoms and any indications wood or berry alterations, natural infections by Phaeoacremonium minimum (syn. P. aleophilum) Phaeomoniella chlamydospora showing brown streaking symptoms, naturally infected minimum, Fomitiporia mediterranea white...

Wood colonizing fungi are specialists that exploit the lignocellulose of cell wall components in host wood cylinders as a carbon sources. Some these specialized fungi, including Fomitiporia mediterranea (Fmed) and Phaeomoniella chlamydospora (Pch), cause disease Esca grapevine. This complex includes grapevine leaf stripe (GLSD) canopies white rot black streaking trunks. The present study gained...
