Nanoporous Quercetin-Loaded Silicon-Stabilized Hybrid Lipid Nanoparticles Alleviate Salt Stress in Tomato Plants

Abstract: The search for more effective methods to alleviate the negative effects of exogenous stresses in plants has inspired nanotechnologies. It is in this context that the use of formulations containing nanoporous silicon-stabilized hybrid lipid nanoparticles acting as delivery systems of the flavonoid quercetin was investigated here. These formulations, referred to as phyto-couriers, proved their efficacy in protecting the important crop model Solanum lycopersicum "Micro-Tom" against salinity. Two phyto-courier for… Show more

“…In a previous study, the phyto-courier functionalised with quercetin (2.5 or 25 mg) was also sprayed several times on the leaves of plants (textile hemp and tomato) and shown to protect against salinity by acting as a nano-biostimulant [ 12 , 13 ]. Once injected or sprayed, quercetin is delivered into the leaf parenchyma, where it is progressively released, increasing its intracellular abundance before stress occurs, thus acting as a biostimulant.…”

“…In a previous study, the external supply of quercetin in the growth medium could protect thale cress, tobacco, and duckweed against the harmful effects of reactive oxygen species (ROS) [ 15 ]. Plants treated with the phyto-courier functionalised with 2.5 mg and 25 mg of quercetin showed decreased symptoms under salt stress, as manifested by the decreased expression of genes related to stress [ 12 ] and by proteomics [ 13 ].…”
