“…Pinot noir plants also showed sporulation on the upper leaf surface, petioles, and stems after 10 days (T10), as reported for susceptible grapevines grown in vitro . SO4 showed only slight sporulation on the abaxial surface of the leaves and small necrotic spots at T10, in agreement with the resistance to downy mildew described in greenhouse and leaf disk tests . Kober 5BB showed no sporulation and diffuse necrotic spots at T10, demonstrating the successful defense response.…”

Emission of volatile sesquiterpenes and monoterpenes in grapevine genotypes following Plasmopara viticola inoculation in vitro

The grapevine (Vitis vinifera) is one of the most widely cultivated fruit crops globally, and one of its most important diseases in terms of economic losses is downy mildew, caused by Plasmopara viticola. Several wild Vitis species have been found to be resistant to this pathogen and have been used in breeding programs to introduce resistance traits to susceptible cultivars. Plant defense is based on different mechanisms, and volatile organic compounds (VOCs) play a major role in the response to insects and pathogens. Although grapevine resistance mechanisms and the production of secondary metabolites have been widely characterized in resistant genotypes, the emission of VOCs has not yet been investigated following P. viticola inoculation. A Proton Transfer Reaction-Time of Flight-Mass Spectrometer (PTR-ToF-MS) was used to analyze the VOCs emitted by in vitro-grown plants of grapevine genotypes with different levels of resistance. Downy mildew inoculation significantly increased the emission of monoterpenes and sesquiterpenes by the resistant SO4 and Kober 5BB genotypes, but not by the susceptible V. vinifera Pinot noir. Volatile terpenes were implicated in plant defense responses against pathogens, suggesting that they could play a major role in the resistance against downy mildew by direct toxicity or by inducing grapevine resistance. The grapevine genotypes differed in terms of the VOC emission pattern of both inoculated and uninoculated plants, indicating that PTR-ToF-MS could be used to screen hybrids with different levels of downy mildew resistance.

“…Differences in susceptibility were also seen between different species of Vitis, as earlier mentioned by several authors (Yu et al, 2012;Boso et al, 2014). Figueiredo et al (2017) explained that following inoculation increase of hydrogen peroxide levels, cellular redox regulation, establishment of ROS signalling and plant cell death seem to be key points differentiating the resistant genotype.…”

SUMMARYTurkey has a very old history of viticulture and also homeland of the grapevine (Vitis spp.). Vitis cultivars belonging to different species are grown in almost every region in the country. However, particularly downy mildew and powdery mildew diseases affect the cultivars belonging to Vitis vinifera. In northern of Turkey Vitis labrusca and hybrids between V.vinifera and V.labrusca are rather common. V.labrusca cultivars or genotypes exhibit generally higher degree of resistance than V. vinifera cultivars. However, resistance level can vary from cultivar to cultivar and even from clone to clone within one cultivar. In this study, different Vitis hybrids and genotypes which exhibit different downy and powdery mildew susceptibility are compared for two years. Especially some V.labrusca hybrids and genotypes appeared resistance for both diseases. On the other hand, interspecific crosses and V.vinifera cultivars were found to be more susceptible. Using resistant lines as parent in later breeding activities, it could be possible grow high quality table cultivars with much fewer pesticide applications or possibly without them. RESUMOA Turquia tem uma longa história vitícola, sendo inclusivé um dos pontos de origem da videira (Vitis spp.). As diferentes espécies de Vitis são cultivadas em quase todas as regiões do país. Doenças como o míldio e oídio afetam em particular as videiras pertencentes à espécie V.vinifera. No Norte da Turquia, as espécies Vitis labrusca e híbridos entre V. vinifera e V. labrusca são bastante comuns. As cultivares/genótipos de V. labrusca exibem um grau de resistência geralmente mais elevado do que as cultivares de V. vinifera. No entanto o nível de resistência pode variar de cultivar para cultivar e até mesmo de clone para clone dentro de uma mesma cultivar. Neste estudo foram comparados diferentes híbridos de Vitis e genótipos com diferentes suscetibilidades ao míldio e ao oídio por um período de dois anos. Alguns híbridos e genótipos de V.labrusca apresentaram resistência a ambas as doenças. Por outro lado, os cruzamentos interespecíficos e as cultivares de V.vinifera foram identificados como sendo mais susceptíveis. Usando linhas resistentes como linha parental em atividades de melhoramento posteriores, poderia ser possível desenvolver cultivares para produção de vinhos de mesa de alta qualidade com menores exigências de aplicações de pesticidas ou possivelmente sem eles.

Background and Aims The susceptibility of winegrape cultivars to Botrytis cinerea is a debated topic, and the available classifications are based on professional experience rather than on experimental data. The main aim of this study was to compare and classify the susceptibility of several winegrape cultivars to B. cinerea and its relation to fruit maturity under two contrasting climatic and cropping conditions. Methods and Results Between 2011 and 2015, three field trials were undertaken in Chile and France, including 13 common cultivars. Both the incidence and severity of the disease were evaluated at harvest, and indices of susceptibility and maturity were calculated on a per site basis. The significant difference in incidence and severity observed among cultivars led to a similar susceptibility classification in both countries. Cabernet Sauvignon, Cabernet Franc, Grenache Noir and Petit Verdot were the most resistant cultivars, whereas Gewürztraminer and Sauvignon Blanc were the most susceptible. Moreover, an exponential and positive relationship was established between indexes of susceptibility and maturity. Conclusions The classification of cultivars according to the susceptibility to B. cinerea was similar in both countries, despite the contrasting climatic conditions and cropping practices. Significance of the Study These findings might be of interest for choosing cultivars that are more resistant to B. cinerea to reduce the number of fungicide applications.
