Background: This study fabricated titanium dioxide nanostructures (TDNS) to control broad bean stain virus (BBSV) in faba bean plants. Protection of faba bean against BBSV was evaluated biologically with respect to virus severity, reduction in BBSV accumulation and expression of a pathogenesis-related gene.
Results: The results indicate that faba bean plants treated with TDNS show a significant reduction in disease severity relative to untreated plants. The regulatory and defense gene involved in the salicylic acid signaling pathway was highly expressed in faba bean plants treated with TDNS compared with untreated plants. The structural features of TDNS, such as the small particle size and suitable shape, contributed to its high efficacy against BBSV. Growth of faba bean plants treated with TDNS was significantly enhanced relative to untreated plants.
Conculsion: TDNS is an important, eco-friendly and safe strategy for controlling BBSV in faba bean and this study is the first report of this control strategy. © 2018 Society of Chemical Industry.
