Abstract

The Agrobacterium-mediated transient expression analysis in intact tissues has emerged as a rapid and useful method to study gene silencing in plants.Potato virus X vector induced silencing of the phytoene desaturase gene(PDS) by Agrobacterium in Nicotiana benthamiana is reported in this paper.The vector construct carried a 409-nucleotide cDNA fragment of the PDS gene.The results showed that the expression of PDS endogenous gene could be inactivated by the expression of 409-bp homologous cDNA fragment carried in the virus vector.
