abstract = {Nanotechnology is emerging as a potential strategy to achieve sustainable agricultural productivity and
global food security. Engineered nanoparticles (NPs) are endowed with the ability to deliver active
ingredients in a responsive manner, reducing the adverse environmental impacts in comparison to the
conventional practices. However, the relationship between NP features (i.e., size, morphology, surface
charge, structure, etc.) and functionality has been scarcely studied so far. In this work, two types of calcium
phosphate NPs were functionalized with the plant resistance-inductor methyl jasmonate (MeJ), which
stimulates the production of secondary plant metabolites (e.g., anthocyanins, stilbenes, and flavonols) in
grapes. The properties of the resulting nanomaterials, namely, elongated apatite (Ap-MeJ) and roundshaped
amorphous calcium phosphate NPs (ACP-MeJ), were studied in detail. In addition, the loading
capacity, release kinetics and elicitor thermal stability of the two nanosystems were compared. The results
indicated that the differences in terms of morphology, crystalline structure and surface charge did not
affect the release kinetics nor the protective action offered by the NPs. However, ACP-MeJ showed much
higher MeJ loading capacity than Ap-MeJ. Both types of nanomaterials exhibited similar performance in
field experiments on Monastrell vineyards (Vitis vinifera L.). Foliar application of ACP-MeJ and Ap-MeJ (1
mM MeJ) produced wines with similar contents of anthocyanins and tannins (around 500 mg L−1 and 1100
mg L−1, respectively), but Ap-MeJ treatment required doubling the NP amount due to its lower MeJ
adsorption capacity. Both treatments produced wines with higher tannin concentration than wines from
non-treated grapes or wine treated with free MeJ at a much higher dosage (10 mM). Results highlight the
potential of ACP and Ap NPs as elicitor nanocarriers enabling enhancement of the quality of wine in a more
sustainable manner.},
