Abstract
Virus-induced gene silencing (VIGS) is a powerful epigenetic tool that allows in a relatively short period of time to down-regulate the expression of an endogenous gene in infected plants for either monitoring the resulting phenotype or enhancing/modifying a particular trait associated with the gene. Here, we describe the utilization of Tobacco rattle virus (TRV) as a vector for the VIGS technique in Arabidopsis plants. The unique ability of TRV to infect both somatic tissues and gametes allows deciphering the role of genes in these tissues simultaneously. As an example, we demonstrate the utilization of TRV to down-regulate the expression of AGO2 and NRPD1a genes in ovules of Arabidopsis plants in order to boost the stable transformation efficiency by floral dip.
