Phosphatidic acid synthesis, octadecanoic pathway and fatty acids content as lipid markers of exogeneous salicylic acid-induced elicitation in wheat.

Activators of plant defence responses against pathogens are a potential alternative to fungicides, and the well-known resistance inducer salicylic acid (SA) protects wheat (Triticum aestivum L.) against powdery mildew. The aim of our work was to investigate through biochemical and molecular approaches whether lipid metabolism alteration could be considered as a characteristic feature of induced resistance in wheat upon SA infiltration.

Solubility, photostability and antifungal activity of phenylpropanoids encapsulated in cyclodextrins.

Effects of the encapsulation in cyclodextrins (CDs) on the solubility, photostability and antifungal activities of some phenylpropanoids (PPs) were investigated. Solubility experiments were carried out to evaluate the effect of CDs on PPs aqueous solubility. Loading capacities and encapsulation efficiencies of freeze-dried inclusion complexes were determined.

Exogenous trehalose induces defenses in wheat before and during a biotic stress caused by powdery mildew.

Powdery mildew would be one of the most damaging wheat diseases without the extensive use of conventional fungicides. Some of the alternative control strategies currently emerging are based on the use of resistance inducers. The disacharride trehalose (TR) is classically described as an inducer of defenses in plants to abiotic stress.

Lipid metabolism is differentially modulated by salicylic acid and heptanoyl salicylic acid during the induction of resistance in wheat against powdery mildew.

Heptanoyl salicylic acid (HSA) is a salicylic acid (SA) derivative obtained by esterification of 2-OH benzoic acid with heptanoic acid. In wheat, the protection levels obtained against Blumeria graminis f. sp.
