摘要利用维多利亚Aequora水母的工程绿色荧光蛋白(GFP),建立了一种利用粒子轰击水稻未成熟胚胎的简易快速转化系统。在35s花椰菜花叶病毒启动子的控制下,mgfp4基因在轰击后12-22天在水稻组织中产生了容易检测和筛选的亮绿色荧光。对转化水稻组织的目视筛选与低水平的抗生素选择有关,大大减少了需要处理的组织数量和恢复转化植物所需的时间。在初代转化水稻植株(T0)及其后代植株(T1)中观察到GFP的表达。我们描述了在体外和体内观察绿色荧光蛋白的各种技术。讨论了这一新的筛选标记在水稻基因工程中的优势。
Abstract An engineered green fluorescent protein (GFP) from the jellyfish Aequora victoria was used to develop a facile and rapid rice transformation system using particle bombardment of immature embryos. The mgfp4 gene under the control of the 35s Cauliflower Mosaic Virus promoter produced bright-green fluorescence easily detectable and screenable in rice tissue 12–22 days after bombardment. Visual screening of transformed rice tissue, associated with a low level of antibiotic selection, drastically reduced the quantity of tissue to be handled and the time required for the recovery of transformed plants. GFP expression was observed in primary transformed rice plants (T0) and their progeny (T1). We describe various techniques to observe GFP in vitro and in vivo. The advantages of this new screenable marker in rice genetic engineering programmes are discussed.
