• Plants are exposed to different types of stressStress throughout their development. In order to tolerate these stressful conditions, plants have a series of systems that allow them to defend themselves and successfully complete their life cycle. One of the most important is the antioxidant defense systemAntioxidant defense system, through which enzymatic and non-enzymatic antioxidantNon-enzymatic antioxidants compounds are synthesized. Antioxidants are necessary as they prevent reactive oxygen or nitrogen species produced at the cellular level from damaging different cellular structures and consequently the integrity of the entire plant. In particular, non-enzymatic antioxidantsNon-enzymatic antioxidants have the great advantage of being non-specific which is why they can neutralize a variety of reactive species. Therefore, it is necessary to maintain adequate antioxidant production to avoid any type of damage caused by reactive species. NanomaterialsNanomaterials have proven to be an effective tool to induce positive responses in plants. This is due to the unique characteristics they possess due to their size ranging from 1 to 100 nm. NanomaterialsNanomaterials can be applied to plants by different routes and enter cells. In this journey, they interact with the different cell structures such as cell wall, cell membrane, different organelles and even with the nucleus, this induces a series of responses that range from the production of reactive oxygen speciesReactive Oxygen Species, to the modification of different metabolic pathwaysMetabolic pathways and also gene expression. Finally, the result is the increase in the production of different secondary metabolites and antioxidants such as phenols, flavonoidsFlavonoids, alkaloidsAlkaloids, carotenoidsCarotenoids, ascorbic acidAscorbic acid, etc. Adequately knowing the mechanism of action of nanomaterialsNanomaterials on the antioxidant system of plants can be useful to plan management strategies aimed at obtaining specific results such as the increase in non-enzymatic antioxidantsNon-enzymatic antioxidants that are useful not only for the plant but also for human health.
