转基因植物是指利用现代生物技术将优良的目的基因导入植物细胞或组织,并在其中进行表达,从而使植物获得新的性状。这一技术克服了植物有性杂交的限制,基因交流范围无限扩大,可将从细菌、病毒、动物、人类、远缘植物甚至人工合成的基因导入植物,使其具有抗虫、抗病毒、耐除草剂、改进农作物品质以及具有保健医疗功效等性状。近年来,转基因植物特别是转基因抗病虫植物发展很快,因其在生产上发挥的重要作用,蕴涵着的巨大市场和商机,引起各方面的广泛关注,世界很多国家纷纷将这一现代生物技 Transgenic plants refers to the use of modern biotechnology will be excellent target gene into plant cells or tissues, and expressed in which, so that plants get new traits. This technology overcomes the limitation of sexual hybridization of plants. The gene exchange scope is infinitely expanded. The gene can be introduced into plants from bacteria, viruses, animals, humans, distant plants or even artificially, so that it has the functions of insect resistance, antivirus, resistance Herbicides, improved crop quality and health and medical efficacy. In recent years, the transgenic plants, especially the transgenic plants resistant to insect pests and diseases have developed rapidly. Because of their important role in production, the huge market and business opportunities implicated in this field have aroused widespread concern in various fields. Many countries in the world have successively adopted this modern organism Skill
