The study investigated whether gaseous methyl jasmonate (MeJa) can induce stilbene accumulation and synthesis potential in response to an abiotic stress (ultraviolet light) in grapevine leaves and berries. It was found that a very low level of atmospheric MeJa (400 nmol/L) can increase stilbene contents in these two organs, although response to MeJa is different between leaves and berries. In leaves MeJa mainly enhances trans-piceid accumulation, while in berries it stimulates trans-resveratrol… 

Methyl Jasmonate Treatment as a Trigger of Resveratrol Synthesis in Cultivated Grapevine

The effect of an exogenous grape berry application of methyl jasmonate (MeJA) on the enhancement of the in vivo resveratrol production was tested. MeJA is a plant volatile that acts as an important

Resveratrol and Its Derivatives as Phytoalexins

This chapter summarizes the steps involved in the synthesis of resveratrol, the most well studied stilbene produced by Vitis vinifera in the context of human health, and shows how this molecule serves as the precursor to a variety of structurally similar molecules found in grapevines and red wines.

Methyl Jasmonate: An Alternative for Improving the Quality and Health Properties of Fresh Fruits

The aim of this review was to clarify the role of MeJA on improving pre- and post-harvest fresh fruit quality and health properties and to influence the influence of Me JA on human health.

Effect of Methyl Jasmonate on Phytoalexins Biosynthesis and Induced Disease Resistance to Fusarium oxysporum f. sp. Vasinfectum in Cotton (Gossypium hirsutum L.)

The high content of gossypetin, gOSSypol, 3-p-coumaroylquinic acid, ferulic acid, and piceatannol and the presence of cichoric acid, chlorogenic acid,and pterostilbene in plants treated with MeJA, contrary to the control, are essential to equip the cotton compounds with defences or phytoalexins against FOV.

Methyl jasmonate reduces decay and enhances antioxidant capacity in Chinese bayberries.

It is indicated that MeJA can effectively reduce fruit decay and improve antioxidant capacity of Chinese bayberry fruit.

Methyl Jasmonate Applications in Viticulture: A Tool to Increase the Content of Flavonoids and Stilbenes in Grapes and Wines

Recently, the interest in methyl jasmonate (MeJ) has increased in viticulture due to its effects on the synthesis of phenolic secondary metabolites in grapes, especially of anthocyanins, flavonols,

Effect of methyl jasmonate in combination with ethanol treatment on postharvest decay and antioxidant capacity in Chinese bayberries.

The results suggest that the combination of MeJA and EtOH had an additive effect in reducing postharvest decay and improving antioxidant capacity in Chinese bayberries.
