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

摘要

According to the invention, a method for producing a rice plant resistant to rice dwarf virus which shows high resistance with a higher level of no disease symptoms, and has been imparted with inhibition or stable resistance, and a resistant variety are provided. A composition for imparting resistance to rice dwarf disease containing an expression inhibitor of at least one gene present in the rice dwarf virus genome. According to the invention, also a method for producing a plant of the family Poaceae which may be infected with rice dwarf virus and has been imparted with resistance to rice dwarf disease, comprising the steps of: A) providing an expression inhibitor 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 is provided.
