“…Phytoplasma infections are important diseases affecting table and wine grape cultivars, but little is known about their effect on grape composition and wine quality (BERTACCINI & DUDUK, 2010 [2]; RUSJAN et al, 2012b [11]; EMBER & al, 2016 [12]; EMBER et al, 2018 [20]). The presence of symptoms associated with these diseases can alter grape composition, change in their sugars, acids and phenolic profiles that contribute greatly to the taste and final alcohol content of wine.…”

Grapevine yellows are a group of infectious diseases, which are usually associated with phytoplasma pathogens, affecting quality of grapes and survival of grapevine. The objective of this work was to evaluate sugars, total phenols and organic acids concentrations in the grapes of four wine cultivars (Fetească Neagră, Pinot Noir, Traminer rose, Chardonnay) healthy and affected by specific symptoms to phytoplasmoses. Berry samples were collected from the Miniș-Măderat (Arad County) and Odobești (Vrancea County) vineyards. Individual sugars and organic acids compounds were identified and quantified in grape berries by the high performance liquid chromatography (HPLC) method using DAD and RID detectors, while total phenolic compounds by using spectrophotometry. The content and composition of sugars and acids varied between healthy and symptomatic plants. Analysis of grape juice revealed reduction in sugars (fructose and glucose) from symptomatic to non-symptomatic vines. Lower values of acidity were obtained in grapes of affected compared to non-affected vines. The differences in acids content between grapes of affected and not affected vines were more pronounced at Pinot Noir variety, with lower concentrations of malic and tartaric acids in grapes from symptomatic vines in both locations studied. The affected grapes did not differ significantly from the healthy ones, regarding to succinic acid content. A notable increase of total phenolic compounds was observed in symptomatic compared to asymptomatic grape berries. The results of this paper showed a clear negative effect of the phytoplasmoses symptoms on grape fruits composition.

“…Similar negative effects have been observed in vine affected by virus infections that recorded decrease of yield and change of grape composition (MARTINEZ & al, 2016 [10]). [20]). The total sugars concentration was lower for white cultivars compared to those of red cultivars.…”

“…'Chardonnay', 'Riesling', 'Cabernet Sauvignon', 'Barbera', 'Sauvignon blanc', and 'Sémillon' are among the most sensitive cultivars [32,33], while some local varieties of Caucasus region (Georgia) as well as Vitis simpsonii, showed low susceptibility [21,34]. On 'Chardonnay' infected by BN, important changes have been reported for gene expression [35], for physiological parameters [36], and for fruit yield and wine quality [37].…”

Epidemiological Investigations and Molecular Characterization of ‘Candidatus Phytoplasma solani’ in Grapevines, Weeds, Vectors and Putative Vectors in Western Sicily (Southern Italy)

Bois noir is caused by ‘Candidatus Phytoplasma solani’, and it is one of the most important and widespread diseases in the Euro-Mediterranean region. There are complex interactions between phytoplasma and grapevines, weeds, and vectors. These ecological relationships can be tracked according to molecular epidemiology. The aims of the 2-year study (2014–2015) were to describe incidence and spatial distribution of Bois noir in a vineyard with three grapevine varieties in Sicily, and to identify the molecular types of the tuf and vmp1 genes in these naturally infected grapevines, according to the potential reservoir plants and vectors. Disease incidence in 2015 was significantly higher in ‘Chardonnay’ (up to 35%) than for ‘Nero d’Avola’ and ‘Pinot noir’ (<5%). All grapevine, weed, and insect samples were infected by ‘Ca. P. solani’ tuf-type b. Most of the collected insects were strictly related to Vitis spp. and belonged to Neoaliturus fenestratus, Empoasca spp., and Zygina rhamni. The characterization of the vmp1 gene revealed six different vmp types in grapevines (V1, V4, V9, V11, V12, V24), three in weeds (V4, V9, V11), and four in insects (V4, V9, V11, V24). Notably, V4, V9, appear both in hosts and vectors, with V9 predominant. Virtual restriction fragment length polymorphism (RFLP) analysis based on the nucleotide sequences supported the data of the conventional RFLP. Connections between the molecular data recorded in the vineyard ecosystems and the application of innovative tools based on the geostatistical analysis will contribute to further clarification of the specific ecological and epidemiological aspects of ‘Ca. P. solani’ in Sicily.

“…It is known, for instance, that “ Ca . Phytoplasma solani” not only causes low harvest but also affects the quality of wine made from susceptible cultivars of Vitis vinifera ( 34 ). Sustainability of lavender production will rely on the prophylactic control of LD but will also have to take into account climate warming, which may influence the fitness and geographic spread of both phytoplasma and insect populations.…”

Lavender Decline in France Is Associated with Chronic Infection by Lavender-Specific Strains of “Candidatus Phytoplasma solani”

The etiology and main pathways for the spread of lavender decline, an infectious disease affecting French lavender production since the 1960s, have remained unclear, hampering the development of efficient control strategies. An extensive survey of lavender fields led to the conclusion that “Candidatus Phytoplasma solani” was chronically infecting declining lavenders and was associated with large infectious populations of Hyalesthes obsoletus planthoppers living on the crop itself. Lavender appeared to be the main reservoir host for lavender-specific phytoplasma strains, an unusual feature for this phytoplasma, which usually propagates from reservoir weeds to various economically important crops. These results point out the necessity to protect young lavender fields from the initial phytoplasma inoculum coming from surrounding lavender fields or from infected nurseries and to promote agricultural practices that reduce the development of H. obsoletus vector populations.
