“…It is an incurable quarantine disease which can only be contained by the elimination of the infected plant material, reduction of the vector number in vineyards and with the removal of the plants mostly known as phytoplasma carriers (bindweed, nettle etc. ) in the close proximity of vineyards (Maixner et al 1995;Stark-Urnau and Kast 2008;Riedle-Bauer et al 2010). BN is caused by stolbur phytoplasma (16SrXII-A subgroup) and is transmitted by the vector Hyalesthes obsoletus Signoret (Hemiptera, Cixiidae) (Maixner et al 1995;Sforza et al 1998).…”

The study was carried out on phytoplasma susceptible grapevine variety 'Chardonnay' (Vitis vinifera L.). The changes in total and individual phenolics, with a focus on hydroxycinnamic acids, flavanols and flavonol contents, were studied in phytoplasmasymptomatic and non-symptomatic berries of Bois noir (BN) infected and uninfected vines. Evident responses to BN infection at veraison have been monitored in a decreased accumulation of caftaric and coutaric acids, pcoumaroyl hexose, procyanidin B1, procyanidin trimer as well as of quercetin-3-O-glucoside, quercetin-3-O-glucuronide and quercetin-3-O-xyloside. At berry softening BN infection statistically increased the content of total phenolics, hydroxycinnamic acids and flavanols, but decreased the flavonol contents, especially at phytoplasmasymptomatic berry skins. Later, at harvest, the BN infection caused an additional significant decrease of coutaric acid and p-coumaroyl pentose contents, moreover of procyanidin B1 and procyanidin dimmers (1, 2, and 3), trimer, kaempferol-3-O-glucoside and of most identified quercetins, except of quercetin-3-O-xyloside. At harvest, non-symptomatic berries from infected plants showed similar dynamics in the total phenolic content compared to berry skins from uninfected plants, but in total flavanols and flavonols content similarity to those symptomatic was observed. The latter decreases grape quality and its antioxidant potential. The Bois noir disease showed specific, local and growth-phase-induced responses regarding the content of phenolics in berry skins, where in particular the differences between phytoplasmasymptomatic and non-symptomatic grapes have to be underlined.

“…Moreover, the RNA-Seq analysis of samples from these grapevines revealed that there was not even a single differentially expressed gene defined between the recovered and uninfected grapevines ( Table S1 ), which indicated that the recovery appeared to have occurred previously, in 2018 or 2019 [ 20 ]. Of note, these samples were collected in a production vineyard where the vines are pruned extensively each year, which is a practice that can have positive effects on grapevine recovery from bois noir disease [ 42 ].…”

Bois noir is the most widespread phytoplasma grapevine disease in Europe. It is associated with ‘Candidatus Phytoplasma solani’, but molecular interactions between the causal pathogen and its host plant are not well understood. In this work, we combined the analysis of high-throughput RNA-Seq and sRNA-Seq data with interaction network analysis for finding new cross-talks among pathways involved in infection of grapevine cv. Zweigelt with ‘Ca. P. solani’ in early and late growing seasons. While the early growing season was very dynamic at the transcriptional level in asymptomatic grapevines, the regulation at the level of small RNAs was more pronounced later in the season when symptoms developed in infected grapevines. Most differentially expressed small RNAs were associated with biotic stress. Our study also exposes the less-studied role of hormones in disease development and shows that hormonal balance was already perturbed before symptoms development in infected grapevines. Analysis at the level of communities of genes and mRNA-microRNA interaction networks revealed several new genes (e.g., expansins and cryptdin) that have not been associated with phytoplasma pathogenicity previously. These novel actors may present a new reference framework for research and diagnostics of phytoplasma diseases of grapevine.

“…However, two other species belonging to the family Cixiidae -Reptalus panzeri (Löw) and cixius wagneri China -were found in this survey. In recent years these species have attracted increasing scientific interest in many European wine-growing areas because of their potential as phytoplasma transmitters (Palermo et al 2004;Riedle-Bauer et al 2006;Chireceanu et al 2011). (Weintraub & Beanland 2006;Chireceanu et al 2011).…”

Tancik J., Seljak G. (2017): Occurrence of Scaphoideus titanus Ball and some other Auchenorrhyncha in the vineyards of western Slovakia. Plant Protect. Sci., 53: 95-100.A study of Auchenorrhyncha was carried out in 2014 and 2015 in 7 vineyard plots with different varieties and pest management strategies in the Nitra wine region and Lesser Carpathian wine region in western Slovakia. The aim of this study was to obtain information related to the presence of potential vector insects associated with grapevine yellows phytoplasmas from the Flavescence dorée and Bois noir groups. Insects were collected by sweeping with an entomological net. Thirty species of Auchenorrhyncha were identified as belonging to 6 families. Cicadellidae were the most abundant, comprising 20 species. Scaphoideus titanus was collected at 4 localities. Identification of the phytoplasma vector is critical to the national strategy for assessment and control of vectors spreading the phytoplasma disease in Slovakian vineyards. The first finding of Metcalfa pruinosa was noticed in vineyards in Slovakia.
