“…Despite the mentioned efforts, the successful application of these novel fungicides as well as their registration among the products admitted in viticulture strictly need a thorough understanding of their biological activity [31,32] and also rely on comprehensive knowledge of the plant machinery controlling defense responses to fungal pathogens. Insights into resistance-involved molecular pathways have been provided by applying "omics" technologies, like microarray [33][34][35] and high throughput sequencing [36].…”

Molecular changes associated with response to powdery mildew (PM) caused by Erysiphe necator have been largely explored in Vitis vinifera cultivars, but little is known on transcriptional and metabolic modifications following application of resistance elicitors against this disease. In this study, the whole transcriptome sequencing, and hormone and metabolite analyses were combined to dissect long-term defense mechanisms induced by molecular reprogramming events in PM-infected ‘Moscato’ and ‘Nebbiolo’ leaves treated with three resistance inducers: acibenzolar-S-methyl, potassium phosphonate, and laminarin. Although all compounds were effective in counteracting the disease, acibenzolar-S-methyl caused the most intense transcriptional modifications in both cultivars. These involved a strong down-regulation of photosynthesis and energy metabolism and changes in carbohydrate accumulation and partitioning that most likely shifted the plant growth-defense trade-off towards the establishment of disease resistance processes. It was also shown that genotype-associated metabolic signals significantly affected the cultivar defense machinery. Indeed, ‘Nebbiolo’ and ‘Moscato’ built up different defense strategies, often enhanced by the application of a specific elicitor, which resulted in either reinforcement of early defense mechanisms (e.g., epicuticular wax deposition and overexpression of pathogenesis-related genes in ‘Nebbiolo’), or accumulation of endogenous hormones and antimicrobial compounds (e.g., high content of abscisic acid, jasmonic acid, and viniferin in ‘Moscato’).

“…Therefore, alternative sustainable strategies for crop protection against pathogens were developed ( Walters et al, 2013 ). These approaches involve the activation of the plants’ natural defense responses through the use of different types of inducers, also called elicitors ( Burdziej et al, 2019 ; Raasch-Fernandes et al, 2019; Ramakrishna et al, 2019 ; Walters et al, 2013 ). These inducers of resistance stimulate natural defense mechanisms of host plants, leading to a systemic acquired resistance (SAR) ( Monci et al, 2019 ; Thakur and Sohal, 2013 ).…”

“…Other research reported instead that the stimulation of the production of secondary metabolites in different plant species can be linked to a decrease in the concentration of primary metabolites 47 , and this has also been verified in grapevine leaves 48 and berries 49 where the application of different elicitors involved a decrease in sugar concentrations.…”

The effect of elicitors on secondary metabolism in vines is receiving much interest, since it has been shown that they are able to increase the accumulation of phenolics, especially anthocyanins. This research aims to investigate the biochemical and molecular effects of the application of a commercial yeast derivative ( Saccharomyces cerevisiae ) on the accumulation of anthocyanins in potted Sangiovese vines. Experiments were performed on three consecutive years and the yeast derivative was applied at the beginning and at the end of veraison. Technological ripening, accumulation of anthocyanins and expression of the main genes involved in their biosynthesis were assessed. Technological ripening proceeded in a similar way in both treated and untreated berries in the three years. A significant increase in the concentration of anthocyanins was instead detected, following the induction by the yeast derivative of the expression of the genes involved in their biosynthesis. The research highlights the possibility of applying a specific inactivated yeast to increase the anthocyanin concentration even under the current climate change conditions, in Sangiovese, a cultivar extremely sensitive to high temperatures.
