Abstract
Virus-induced gene silencing (VIGS) is a powerful method to study gene function in plants. Tobacco rattle virus (TRV)-based VIGS vector is the most efficient VIGS vector so far. This method was originally developed by the Dinesh-Kumar's group (Liu et al., 2002) . Here, we describe a rapid and high efficient TRV-based VIGS method for knocking down genes in Nicotiana benthamiana. For TRV-based VIGS, Agrobacterium culture containing pTRV1 and Agrobacterium culture containing pTRV2 with plant target gene fragment are mixed and infiltrated into the lower leaves of plant. After 2-3 weeks post infiltration, plant target gene will be silenced.
