METHOD FOR PRODUCING RICE RESISTANT TO RICE DWARF VIRUS BY RNA INTERFERENCE

摘要

According to the invention, a method for producing rice resistant to rice dwarf virus, which has been imparted inhibitory or stable resistance and shows resistance displaying no symptoms at a higher level and a resistant cultivar are provided. A composition for imparting resistance to rice dwarf disease, containing an inhibitor of expression of at least one gene present in the rice dwarf virus genome. The invention also provides a method for producing a plant of the Poaceae family which has been imparted resistance to rice dwarf disease and can be infected with rice dwarf virus, comprising the steps of: A) providing an inhibitor of expression of at least one gene present in the rice dwarf virus genome; B) introducing the expression inhibitor into a cell of the plant; C) selecting a cell of the plant transfected with the expression inhibitor; and D) producing a transgenic plant by redifferentiating the selected cell.
