“…Altogether, the antilisterial efficacy of resveratrol in food was observed in lettuce model medium and chicken juice, but not in milk, where a weakening or even neutralization of resveratrol action was observed. A comparable behaviour was previously described for ( E )‐pinosylvin, a naturally occurring stilbene similar to resveratrol, where neither sauerkraut nor gravlax abolished pinosylvin activity, but milk totally neutralized its antimicrobial effect . The interaction of resveratrol with milk proteins as well as the incorporation of resveratrol in fat may modulate its bioavailability .…”

“…In the early infection phase, the accumulation of the aglycones piceatannol and resveratrol was correlated with lower susceptibility, whereas in the later infection phase in August, this applied to the glucosides astringin, isorhapontin, and piceid, likely because of proceeding glycosylation for higher compounds stability (Levin, 1971; Slimestad and Hostettmann, 1996). The antifungal effect of stilbenes was reported in several studies (Chong et al, 2009; Hammerbacher et al, 2011; Plumed-Ferrer et al, 2013) and may be one reason why older needles with a high constitutive stilbene level are never infected by C. rhododendri . A strong correlation between isorhapontin concentrations and susceptibility was also found in spruce phloem infected by E. polonica (Brignolas et al, 1998), and astringin was shown to limit the depth of hyphal penetration by Heterobasidion annosum in the bark (Lindberg et al, 1992).…”

Foliar Phenolic Compounds in Norway Spruce with Varying Susceptibility to Chrysomyxa rhododendri: Analyses of Seasonal and Infection-Induced Accumulation Patterns

et al. 2017

Secondary phenolic metabolites are involved in plant responses to various biotic stress factors, and are apparently important for the defense against fungal pathogens. In this study, we investigated their role in defense against the rust Chrysomyxa rhododendri in Norway spruce. The fungal pathogen undergoes a seasonal lifecycle with host shift; after overwintering in rhododendron shrubs, it attacks the sprouting current-year spruce needles and causes needle fall in autumn. Repeated infections lead to reduced timber yield and severe problems with rejuvenation in subalpine Norway spruce forests. Trees with varying susceptibility to infection by C. rhododendri were selected and foliar phenolic composition was assessed using UHPLC-MS. We report on seasonal accumulation patterns and infection-related changes in the concentrations of 16 metabolites, including flavonoids, stilbenes, simple phenylpropanoids and the precursor shikimic acid, and their correlation with the infection degree of the tree. We found significant variation in the phenolic profiles during needle development: flavonoids were predominant in the first weeks after sprouting, whereas stilbenes, picein and shikimic acid increased during the first year. Following infection, several flavonoids and resveratrol increased up to 1.8 fold in concentration, whereas picein and shikimic acid were reduced by about 70 and 60%, respectively. The constitutive and early stage infection-induced concentrations of kaempferol, quercetin and taxifolin as well as the late stage infection-induced concentrations of stilbenes and picein were negatively correlated with infection degree. We conclude that a combination of constitutive and inducible accumulation of phenolic compounds is associated with the lower susceptibility of individual trees to C. rhododendri. The potentially fungicidal flavonoid aglycones may limit hyphal growth and prevent development of infection symptoms, and high levels of stilbenes may impede the infection of older needles. The presented results underline a highly compound-specific seasonal accumulation and defense response of Norway spruce and may facilitate the selection of promising trees for breeding programs.

“…A number of studies showed that stilbenes inhibit growth of food-associated bacteria in vitro. For example, Plumed-Ferrer et al (2013) found that a group of wood-associated stilbenes possess clear antimicrobial activities against some food pathogens and spoilage organisms, including both Gramnegative (Salmonella) and Gram-positive bacteria (Listeria, Staphylococcus). According to Ferreira et al (2014), resveratrol exerts bactericidal activity against Arcobacter butzleri and Arcobacter cryaerophilus obtained from food samples.…”

Main conclusion This review analyzes the advances in understanding the natural signaling pathways and environmental factors regulating stilbene biosynthesis. We also discuss the studies reporting on stilbene content and repertoire in plants.Stilbenes, including the most-studied stilbene resveratrol, are a family of phenolic plant secondary metabolites that have been the subject of intensive research due to their valuable pharmaceutical effects and contribution to plant disease resistance. Understanding the natural mechanisms regulating stilbene biosynthesis in plants could be useful for both the development of new plant protection strategies and for commercial stilbene production. In this review, we focus on the environmental factors and cell signaling pathways regulating stilbene biosynthesis in plants and make a comparison with the regulation of flavonoid biosynthesis. This review also analyzes the recent data on stilbene biosynthetic genes and summarizes the available studies reporting on both stilbene content and stilbene composition in different plant families.
