Molecules, Vol. 28, Pages 1478: Methyl Jasmonate and Nanoparticles Doped with Methyl Jasmonate affect the Cell Wall Composition of Monastrell Grape Skins Molecules doi: 10.3390/molecules28031478 Authors: María José Giménez-Bañón Diego Fernando Paladines-Quezada Juan Daniel Moreno-Olivares Juan Antonio Bleda-Sánchez José Ignacio Fernández-Fernández Belén Parra-Torrejón Gloria Belén Ramírez-Rodríguez José Manuel Delgado-López Rocío Gil-Muñoz The structural composition of the cell wall of grape skins is related to the cell wall integrity and subsequent extraction of the different compounds that are contained inside vacuoles and also the cell wall breakdown products. Different reports have established that methyl jasmonate (MeJ) produces changes in the composition of the grape skin cell wall. The use of elicitors to promote the production of secondary metabolites in grapes has been studied in several reports; however, its study linked to nanotechnology is less developed. These facts led us to study the effect of methyl jasmonate (MeJ) and nanoparticles doped with MeJ (nano-MeJ) on the cell walls of Monastrell grapes during three seasons. Both treatments tended to increase cell wall material (CWM) and caused changes in different components of the skin cell walls. In 2019 and 2021, proteins were enlarged in both MeJ and nano-MeJ-treated grapes. A general decrease in total phenolic compounds was detected with both treatments, in addition to ...
