Abstract:
Interaction between a virus and a host plant is of great current interest. In light of this,
given article attempts to determine the role of virus proteins in an activation of defence mechanisms
associated with salicylic acid in Solanum lycopersicum (tomatoes) during Tomato Bushy Stunt Virus
(TBSV) infection. The influence of TBSV on tomatoes Money Maker cultivar and the tolerance of
the cultivar to an infection were studied. No symptoms were observed during TBSV amplification in
Money Maker. Protein P19 was identified as one of the signaling proteins in response to which plants
activate a salicylic acid-induced defense mechanism. It might indicate the role of TBSV P19 protein
as an initiator of salicylic acid-induced resistance. The obtained results might help to elucidate
defence mechanisms of plants from viruses.
