遗传工程师们相信,农业是他们的工作最有希望的出路之一。这些科学家们希望创造出更有营养价值,更能抗病和固氨的新型植物种。现在,美国威斯康星大学的一个研究小组已经迈出了具有重大意义的第一步。他们已研究出一种能产生新植物和获得蛋白来源的遗传技术。科学家们用这种新技术成功地培养出一种新的温室种子—“向日豆”。 Genetic engineers believe agriculture is one of the most promising ways out of their work. These scientists want to create new plant species that are more nutritious, disease-resistant and ammonia-fixing. Now a research team at the University of Wisconsin has taken the first significant step. They have developed a genetic technique that produces new plants and sources of protein. Using this new technology, scientists have succeeded in cultivating a new greenhouse seed, “Xiang Riyu”.
