TRANSGENIC PLANT EXPRESSING SOYBEAN GLYCININ

摘要

Transgenic rice plants obtained by isolating the promoter region of a glutelingene capable of expressing the gene in the albumen of rice seed; constructinga vector wherein natural and modified soybean glycinin genes are ligated tothe downstream of the promoter; and then transferring this vector intocultured rice cells. As the results of examinations on the tissue specificityand the morphology of the soybean glycinin expressed in the transgenic riceplants thus obtained, it is found out that the soybean glycinin expressed inrice is accumulated in rice seeds and the thus accumulated soybean glycininexists as the processed maturation type.
