Stimulation of resistance genes and antioxidant enzymes in lettuce by nano metal oxides against root rot caused by Rhizoctonia solani.

ABSTRACT: Root rot, caused by Rhizoctonia solani L., is becoming an increasing issue for lettuce. Nanoparticles (NPs) are emerging as a promising approach for managing biotic stress, offering advantages surpassing traditional control methods. This studyaimed to evaluate the effectiveness of silicon dioxide (SiO2), copper oxide (CuO), and gamma iron oxide (γFe2O3) nanoparticles in inducing systemic resistance (SR) in lettuce against R. solani by examining the molecular response, particularly the expression of pathogenesis-related and stress-regulatory genes. Additionally, assessed total protein contents, photosynthetic pigments, Hydrogen peroxide (H2O2), malondialdehyde (MDA), and antioxidant enzymes. The results demonstrated that NPs significantly reduced basal rot symptoms and decreased the Area Un
