“…The most used elicitor as a biostimulant of grapevine tissues is methyl jasmonate. The use of benzothiadiazole and methyl jasmonate on different Monastrell clones increased the contents of anthocyanins, flavonols, stilbenes, and seed and skin tannins . In addition, these elicitors applied to the same grapevines differentially increased the concentrations of terpenes and norisoprenoids in the grapes and wines .…”

A review of the use of biostimulants in the vineyard for improved grape and wine quality: effects on prevention of grapevine diseases

Foliar application of biostimulants (including resistance inducers or elicitors) in the vineyard has become an interesting strategy to prevent plant diseases and improve grape quality on the grapevine. This also represents a partial alternative to soil fertilisation, avoiding some of the negative effects to the environment from leaching of nutrients into the groundwater. The foliar applications that most promote the synthesis of secondary metabolites in grape berries are treatments with nitrogen, elicitors, other biostimulants, and waste from the agricultural industry. However, the impact of their use in the vineyard depends on a number of conditions, including mainly the type of compound, application rate, timing and number of applications, and cultivar. This review thus summarises the influence of biostimulants as foliar applications to grapevines on grape amino acids and their phenolic and volatile concentrations, to define the most important factors in their effectiveness. © 2018 Society of Chemical Industry.

Resveratrol and its derivatives are a class of polyphenolic compounds recognized for their outstanding biological properties based on clinical trials. In addition, their possible uses in nutraceutics, cosmetics, and as pharmaceutics create a need for large‐scale production with the possibility to use sustainable sources. In this review, we report on the biotechnological production of resveratrol and some of its derivatives through plant cell suspensions, such as grapevine cell culture systems. These cultures usually need elicitation. Methyljasmonate, cyclodextrins, the combination of both and chitosan are the elicitors leading to the best responses in terms of resveratrol amounts produced in flasks. Production performances of resveratrol can be optimized in flasks for scale‐up in large culture volumes. We summarize the plant cell culture systems used for resveratrol bioproduction and transfer experiments from flasks to bioreactors as well as elicitor‐mediated upregulation of the defense genes in those plant culture systems.
