【摘要】 研究比较了外源基因导入水稻的三种技术体系，即ＰＥＧ介导法，基因枪法和农杆菌介导法．综合考虑转化频率、转化周期、转化难度和转化成本等因素，认为在水稻转基因研究中，最经济、有效和易行的技术体系是农杆菌介导法．更多还原

【Abstract】 Three rice genetic transformation systems,PEG Mediated,Biolistic Gun and Agrobacterium Mediated were compared.After due considering transformation frequency,transformation period,transformation cost and transformation difficulty,Agrobacterium Mediated system was selected as one more economical,more efficient and more simple rice gene transformation system.更多还原
