This study is unique as it compares traditional and high-resolution culture-independent approaches using the same set of samples to study the saprotrophic fungi on Vitis vinifera. We identified the saprotrophic communities of table grape (Red Globe) and wine grape (Carbanate Gernischet) in China using both traditional and culture-independent techniques. The traditional approach used direct observations based on morphology, single spore isolation and phylogenetic analysis yielding 45 taxa which 19 were commonly detected in both cultivars. The same set of samples were then used for Illumina sequencing which analyzed ITS1 sequence data and detected 226 fungal OTUs, of which 176 and 189 belong to the cultivars Carbanate Gernischet and Red Globe, respectively. There were 139 OTUs shared between the two V. vinifera cultivars and 37 and 50 OTUs were specific to Carbanate Gernischet and Red Globe cultivars respectively. In the Carbanate Gernischet cultivar, Ascomycota accounted for 77% of the OTUs and in Red Globe, almost all sequenced were Ascomycota. The fungal taxa overlap at the genus and species level between the traditional and culture-independent approach was relatively low. In the traditional approach we were able to identify the taxa to species level, while in the culture-independent method we were frequently able to identify the taxa to family or genus level. This is remarkable as we used the same set of samples collected in China for both approaches. We recommend the use of traditional techniques to accurately identify taxa. Culture-independent method can be used to get a better understanding about the organisms that are present in a host in its natural environment. We identified primary and secondary plant pathogens and endophytes in the saprotrophic fungal communities, which support previous observations, that dead plant material in grape vineyards can be the primary sources of disease. Finally, based on present and previous findings, we provide a worldwide checklist of 905 fungal taxa on Vitis species, which includes their mode of life and distribution.

“…In addition, experiments carried out with axenic plants, trunks and shoots of the Carmenère cv. showed that there were no differences in pathogenicity between D. mutila and D. seriata (Díaz et al, 2013). However, the susceptibility of different wine grape cultivars to D. seriata and D. mutila has not been reported to date.…”

“…Fungal species belonging to the Botryosphaeriaceae are responsible for the death of part of the plant, reducing the productivity and profitability of this crop (Gubler et al, 2010). Both D. seriata and D. mutila are associated with the Botryosphaeria die-back in Chile (Díaz et al, 2013;Morales et al, 2012). These fungi have been detected in table grape vineyards where no differences were observed among the Thompson Seedless, Red Globe and Flame Seedless cultivars, which were equally susceptible to infection by D. mutila, D. seriata and Spencermartinsia viticola (Morales et al, 2012).…”

Canes obtained from one-year-old stems of the grapevine cultivars Cabernet Franc, Malbec, Merlot, Sauvignon Blanc and Syrah (all non-grafted) were used as models to test their susceptibility to Diplodia seriata and Diplodia mutila. The results showed that the mean length of lesions caused by D. mutila was 3.2 times larger than that produced by D. seriata. In addition, the Cabernet Franc and Syrah cultivars were the most susceptible to D. mutila, while Merlot and Malbec were the least susceptible. No significant differences were observed between cultivars inoculated with D. seriata. The results are discussed in terms of the susceptibility of the different grapevine cultivars to both pathogens.

“…The worldwide economic cost for the replacement of dead grapevine plants has been estimated more than 1.5 billion of dollars per year [1]. However, that cost may be underestimated in view of the individual regional data found in literature, for example nearly 13% of French vineyards are affected by GTDs compared to 22% in Chile [2,3].…”

Grapevine trunk diseases (GTDs) are currently one of the most important problems for grapevine plant and wine industry, causing important economic cost in Castilla-La Mancha, Spain. Traditionally, GTDs were associated with diseases present in mature grapevines, however in recent years the incidence of young vine decline has been increasing. In this work, from 2009 to 2016, 250 young grapevine plants have been analysed by fungal isolation and characterization. In addition, during 2017, 32 mature plants showing decline symptoms were analysed. Both kinds of plants were analysed in order to identify the main fungal trunk pathogens present in Castilla-La Mancha region. As a result, it was possible to isolate species associated with black-foot disease (Cylindrocarpon-like anamorphs), esca and Petri disease (Phaeomoniella chlamydospora and Phaeoacremonium spp.), and Botryosphaeria dieback. All these pathogens were isolated from young and mature plants, this fact could suggest a common origin. The lack of effective control measures for these diseases makes it necessary to implement an integrated disease management strategy that provides an efficient approach to reduce infections in nurseries and get better results in infected vineyards.
