Abstract
This review article is devoted to the use of selenium nanoparticles (Se NPs) in plant production. The review analyzes relevant literature data for the last 10 years, considering the effect of Se NPs application on morphometric and biochemical parameters of plants. A number of actual works demonstrating the efficiency of Se NPs use in the composition of nanocomposites based on synthetic and natural polymers are considered separately. Possible mechanisms of Se NPs absorption and transport and their further activity in plant cells of agricultural crops in the context of biostimulating, biofortification, nutraceutical, and antioxidant activities of Se NPs, as well as the efficiency of Se NPs application under stress factors are discussed. The review provides data demonstrating the antibacterial and antifungal activities of Se NPs in the context of their activity against a wide range of phytopathogens. Also, we conduct a detailed comparative analysis of the relative efficiency of Se NP application with mineral Se-containing compounds (SeO32− and SeO42−), as well as organic forms of Se (SeCys and SeMet).
