Highly efficient suppressor-dependent protein expression in plants with a viral vector

摘要

A series of viral vectors derived from foxtail mosaic virus, sunn hemp mosaic virus and white clover mosaic virus sequences, and which are capable of expressing heterologous proteins in plants, including the tobacco, Nicotiana benthamiana, and cowpea, bean, and other legumes with the properties of unusually limited expression in the absence of gene silencing suppressors and high level expression in their presence. In a preferred embodiment, these viral vectors may be introduced via agroinoculation, and expression of the heterologous gene may be inducible with little or no leakiness in the absence of induction.
