【Abstract】 According to depositions of nanostructured silica in plants and chemically synthesized nanostructured silica sprayed into leaves and physical properties of leaf conferred by silica depositions as well, the first reaction of high specific supramolecular recognition process of fungi spores and host surfaces is reviewed. Nanostructured silica may change leaf physical properties including topography and hydrophobicity and affect extracellular matrix (ECM) release and formations of germ tube, appressorium and penetration peg. The measure of targeted disease control is discussed.更多还原
