【摘要】 获得转基因植株是植物基因工程的基础,但是由于转化效率较低,在转基因的过程中通常需要一个有效筛选细胞和组织的手段,于是选择标记基因被广泛应用。然而,选择标记基因的使用,存在生物安全性和环境安全性隐患。因此,建立一个安全高效稳定的大豆转化体系,是改善大豆产量、品质、抗逆能力,培育新型大豆品种的保障。该文综述了新型标记基因在大豆育种上的应用及转基因技术在大豆和其它作物育种中的应用。更多还原

【Abstract】 A prerequisite for plant genetic engineering is to produce transgenic plants.Selectable marker genes have been widely used in plant transformation because of the low efficiency of transgenic integration.However,the use of selectable marker genes would affect the safety evaluation of transgenic plants and there are perceived risks in bio-safety and environmental safety.An effective soybean transformation system is necessary to breed new soybean varieties in improving the yield,quality and resistance.In this review,the new selectable marker genes in soybean breeding and transgenic technology in crops breeding were summarized.更多还原
