The effect of complete or partial inactivation of p19 and p41 proteins with nuclease activity on the level of viral infection of TBSV

Abstract

The TBSV P19 protein is a plant RNA interference suppressor. The study of the mechanism of action of the TBSV P19 protein as a protective strategy of the virus has an important role in understanding the interaction of two organisms in the struggle for survival. The P19 protein, encoded by the Tomato bushy stunt virus (TBSV), is a potent suppressor of RNA-interference and plays an important role in the infection of plants with Nicotiana benthamiana virus. Expression of the P19 protein leads to complete plant collapse, which leads to more pronounced virus damage.
