<;P>;PROBLEM TO BE SOLVED: To provide an accumulation inhibitor of a rice allergen protein, to provide transgenic rice in which the accumulation of the rice allergen protein is inhibited, to provide a method for producing seeds thereof, to provide a method for inhibiting the accumulation of the rice allergen protein utilizing the agent and to provide the transgenic rice and seeds obtained by the method. <;P>;SOLUTION: The removal of an allergen protein of 14-20 kDa which is a main allergen of rice is succeeded by an RNA interference method utilizing a conserved region between allergen protein gene groups of 14-20 kDa. <;P>;COPYRIGHT: (C)2007,JPO&INPIT
