Antiviral activity of secondary metabolites of Teucrium species

Unefficiency of chemical treatments and recent plant protection that is focused on natural products, have pointed the importance of finding natural substances that can help in a control of plant virus diseases. Current knowledge about the antiviral effects of essential oils, although limited, indicates the potential of these secondary metabolites to control or at least reduce the spread of viral infection. Essential oils isolated form Teucrium species showed antiviral activity in tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) infected plants. The aim of this chapter is to present findings dealing with antiphytoviral potential of selected species of genus Teucrium and to improve the knowledge about possible application of essential oils for the prevention of diseases caused by plant viruses. Essential oil of Teucrium arduini applied on the leaves of local host plants, significantly reduced the number of lesions on both TMV and CMV infected plants. Aside from Teucrium arduini, four additional Teucrium species (T. montanum, T. polium, T. chamaedrys and T. flavum) are also source of bioactive molecules with antiphytoviral activity against CMV infection. This promising biological activity of Teucrium species opens new area of research that could help in a control of virus diseases of plants.
