VIRUS GENE FOR ACQUIRING TENUIVIRUS-RESISTANT PLANT USING RNA INTERFERENCE TECHNIQUE

摘要

The purpose of the present invention is to provide a practically usable method for constructing a plant, which has a resistance to a virus belonging to the genus Tenuivirus (tenuivirus), and a resistant variety. Disclosed is a composition for imparting a resistance to a viral disease caused by a tenuivirus,which comprises an expression inhibitor for at least one gene occurring in the genome of the tenuivirus. Also disclosed is a method for producing a plant belonging to the family Poaceae being possibly infected with tenuiviruses, to which a tolerance to a viral disease caused by a tenuivirus has been imparted,comprising: A) a step for providing an expression inhibitor for at least one gene occurring in the genome of the tenuivirus; B) a step for transferring said expression inhibitor into cells of the plant; C) a step for selecting plant cells into which said expression inhibitor has been transferred; and D) a step for re-differentiating the selected cells and thus constructing a transgenic plant.
