“…Previous work has demonstrated that two biochemical processes are indicative of downy mildew resistance in grapevines. One is the synthesis of callose in stomata ) and the second is the synthesis of resveratrol and its subsequent oxidation to ɛ-and δ-viniferins (Langcake 1981;Pezet et al 2003Pezet et al , 2004a. The obvious priming for accumulation of different flavonoids in BABA-primed, infected grapevine plants compared to untreated water controls ( Fig.…”

BABA, a non-protein amino acid, was used to induce resistance in grapevine against downy mildew. BABA-induced resistance was observed in the susceptible cv. Chasselas as well as in the resistant cv. Solaris. Following BABA treatment, sporulation of Plasmopara viticola was strongly reduced and the accumulation of stilbenes increased with time following infection. Induction of trans-piceide, trans-resveratrol and, more importantly, of trans-ɛ-and trans-δ-viniferin and trans-pterostilbene was observed in BABA-primed Chasselas. On the other hand, induction of transresveratrol, trans δ-viniferin and trans-pterostilbene was observed in BABA-primed Solaris. The accumulation of stilbenes in BABA-primed Solaris was much higher than that found in BABA-primed Chasselas. Furthermore, BABA-treatment of Solaris led to a rapid increase in transcript levels of three genes involved in the phenylpropanoid pathway: phenylalanine ammonia lyase, cinnamate-4-hydroxylase and stilbene synthase. BABA-primed Chasselas showed increased transcript levels for cinnamate-4-hydroxylase and stilbene synthase. Here we show that pre-treatment of a susceptible grapevine cultivar with BABA prior to infection with P. viticola primed the accumulation of specific phytoalexins that are undetectable in non-BABA-primed plants. As a result, the susceptible cultivar became more resistant to downy mildew.

“…Resveratrol and piceid are much less toxic against P. viticola than viniferins [14]. Viniferins are supposed to be involved depending on the cultivar resistance to the pathogen [22]. For the Cabernet Sauvignon, which has a low degree of resistance to P. viticola, the less toxic compounds for pathogen are localized at the leaf infection sites where the viniferins are not accumulated.…”

“…MSI allowed the identification and mapping of resveratrol and pterostilbene but the biosynthesis of some other stilbenes is also expected to be induced in grapevine leaves and even berries in response to pathogen infection or UV irradiation [19][20][21]. Besides the glycosylation of stilbenes (e.g., piceids), oxidative oligomerization of resveratrol catalyzed by plant peroxidases may occur and several of them have been identified in stressed grapevine leaves [22][23][24].…”

MALDI Mass Spectrometry Imaging for the Simultaneous Location of Resveratrol, Pterostilbene and Viniferins on Grapevine Leaves

Abstract:To investigate the in-situ response to a stress, grapevine leaves have been subjected to mass spectrometry imaging (MSI) experiments. The Matrix Assisted Laser Desorption/Ionisation (MALDI) approach using different matrices has been evaluated. Among all the tested matrices, the 2,5-dihydroxybenzoic acid (DHB) was found to be the most efficient matrix allowing a broader range of detected stilbene phytoalexins. Resveratrol, but also more toxic compounds against fungi such as pterostilbene and viniferins, were identified and mapped. Their spatial distributions on grapevine leaves irradiated by UV show their specific colocation around the veins. Moreover, MALDI MSI reveals that resveratrol (and piceids) and viniferins are not specifically located on the same area when leaves are infected by Plasmopara viticola. Results obtained by MALDI mass spectrometry imaging demonstrate that this technique would be essential to improve the level of knowledge concerning the role of the stilbene phytoalexins involved in a stress event.

“…Subsequent storage in vacuoles may protect plant cells from potentially their toxic effects. In susceptible cultivars, such as Gamay, Gamaret, Pinot Noir and Chasselas, resveratrol was found to be either glycosylated or present in very low concentrations (Pezet et al 2004). Studies of grapevine varieties resistant to P. viticola reported that Eresveratrol is probably rapidly oxidized into toxic stilbenes, such as e-and d-viniferins, while in susceptible cultivars, it is rapidly glycosylated into less toxic piceid (Pezet et al 2004).…”

The stilbene profile in edible berries

2018

View full text Add to dashboard Cite

Edible berries are becoming increasingly popular to consume in fresh, dried, frozen or processed forms due to their high content and wide diversity of bioactive compounds with considerable health benefits. Among the wide variety of phytochemicals found in berries are stilbenes, which demonstrate a broad range of biological and pharmacological activities. Their content depends on many factors, including the cultivar, ripening stage, climatic conditions, agronomic management, storage conditions and postharvest management. However, the application of various abiotic and biotic external stimuli could be a strategy for increasing the production of stilbenes in edible berries. To date, several different elicitors, as inducers of plant secondary metabolite stilbenes, have been applied in different studies. This review focuses on the isolation and identification of stilbenes from edible berries and presents the influence of different external stimuli on their profile in grapes.
