先前，我们已获得的含玉米Ubiquitin启动子──bar基因嵌合表达序列的纯合转基因水稻植株（品种山法师）有高水平的bar基因表达，抗除草剂双丙氨酰膦。将同样的基因序列导入具有经济价值的粳稻栽培品种日本暗的原生质体，获得了该品种的民代转基因植株。由于双丙氨酰膦不仅对寄
Previously, the homozygous transgenic rice plants (Brassica campestris) that we had obtained with the chimeric Ubiquitin promoter-bar gene chimeric expression sequence had high bar gene expression and was resistant to the herbicide balanis. The same gene sequence was introduced into Japanese dark protoplasts of japonica rice cultivar with economic value, and transgenic transgenic plants of this variety were obtained. Since bialaphos is not only sent
