Method and means for producing barley yellow dwarf virus resistant cereal plants

摘要

The invention relates to methods for producing transgenic cereal plants resistant to Barley Yellow Dwarf Virus, particularly in the presence of co-infecting Cereal Yellow Dwarf Virus, by stably integrating into the cells of the transgenic plant a chimeric gene comprising a DNA region operably linked to plant expressible promoter in such a way that the RNA molecule may be transcribed from the DNA region, the RNA molecule comprising both sense and antisense RNA capable of pairing and forming a double stranded RNA molecule or hairpin RNA.
