MDMV BASED VECTOR FOR GENE EXPRESSION AND SILENCING

摘要

A plant expression vector comprising a nucleic acid sequence encoding a polyprotein product is disclosed. The polyprotein product comprising Maize Dwarf Mosaic Virus (MDMV) polypeptides and a heterologous polypeptide of interest, the heterologous polypeptide of interest being cleaved of the MDMV polypeptides upon expression in a plant cell, and wherein the plant expression vector is capable of spreading in a plant. A plant cell, a plant and methods of producing plants are also provided.
