S-nitrosoglutathione reductase (GSNOR) reduces the nitric oxide (NO) adduct S-nitrosoglutathione (GSNO), an essential reservoir for NO bioactivity. In plants, GSNOR has been found to be important in resistance to bacterial and fungal pathogens, but whether it is also involved in plant-herbivore interactions was not known. Using a virus-induced gene silencing (VIGS) system, the activity of GSNOR...

Insect herbivory activates plant defense mechanisms and releases a blend of herbivore-induced volatiles (HIPVs). These volatile compounds may be involved in plant-plant communication induce response undamaged plants. In this work, we investigated whether the exposure sweet pepper plants to HIPVs [ (Z) -3-hexenol, -3-hexenyl acetate, propanoate, butanoate, hexyl methyl salicylate jasmonate] immu...

The effect produced by the application of methyl jasmonate (MeJA) in vineyards is clear, but this a product that, despite its efficiency, expensive, volatile and difficult to dissolve. Regarding increasing MeJA use new forms are proposed article, such as calcium phosphate nanoparticles with two different morphologies: amorphous (ACP) crystalline (Ap). In addition, few studies addressed so far h...

Tomato, which is regarded as an important worldwide crop, susceptible to gray mold caused by Botrytis cinerea. Selenium and methyl jasmonate can act antifungal agents against pathogenic infections. To clarify the effect of selenium on fungal pathogen, spore germination mycelial growth B. cinerea were investigated in vitro using rate method. Additionally, electrical conductivity, soluble protein...

The involvement of jasmonic acid (JA), different JA-related metabolites, salicylic (SA), indole-3-acetic (IAA) and abscisic (ABA) in the heat-induced cross-adaptation to chilling has been investigated citrus fruit. effects heating ‘Fortune’ mandarins at 37 ºC, storing them a temperature (2 ºC) after being exposed, or not, heat-conditioning treatment (3 d on levels these signalling molecules wer...

Oxylipins of the jasmonate pathway and synthetic functional analogs have been analyzed for their elicitor-like activities in an assay based on the induced accumulation of glyceollins, the phytoalexins of soybean (Glycine max L.), in cell suspension cultures of this plant. Jasmonic acid (JA) and its methyl ester showed weak phytoalexin-inducing activity when compared to an early jasmonate biosyn...

Stilbenes are defense molecules produced by grapevine in response to stresses including various elicitors and signal molecules. Together with their prominent role in planta, stilbenes have been the center of much attention in recent decades due to their pharmaceutical properties. With the aim of setting up a cost-effective and high purity production of resveratrol derivatives, hairy root lines ...
