Abstract
Infections of plants by viruses induce plant disease and associated symptoms result in economic losses in crops. The study of viral infections has led to the discovery of RNA silencing as a plant defence mechanism against plant
pathogens and of viral suppressors of gene silencing as the viral mechanism to counter such plant defence. In addition, it has led to the unravelling of the role of small RNAs (sRNAs) in plant development. Developmental symptoms associated with plant disease have been attributed in some
systems to the effects of the viral suppressors of gene silencing on the normal performance of the plant sRNA machinery. In the model system Arabidopsis thaliana - Turnip mosaic virus, a potyvirus two different strains of which induce very different disturbances of the plant development, we have identified the viral determinant of developmental symptoms in the P3/p6k1 region, different from the described viral suppressor of gene silencing (HC-Pro). This result emphasises the role of the different viral proteins in disease induction, opens the way to deepen our knowledge of the potyviral proteins in the viral cycle and also to better understand plant growth regulation. Results will be presented and discussed.
