摘要: 通过对农杆菌菌液浓度、侵染时间、预培养时间和共培养时间等影响转化效率的因素进行优化,建立了合欢农杆菌转化体系。在此基础上,利用农杆菌介导法将TaNHX2基因导入合欢基因组内,获得大量Kan抗性再生植株。常规PCR和实时荧光PCR检测结果表明,外源基因已整合到合欢基因组中,并正常转录。

Abstract: Some factors influencing the transformation efficiency, such as the concentration and infection duration of Agrobacterium tumefaciens, pre-culture and co-culture duration, were optimized to establish a stable Agrobacterium mediated gene transformation protocol of Albizia julibrissin Duraxx. The TaNHX2 gene was transformed into A.julibrissin. Mediated by A.tumefaciens, lots of regenerated plants resistant to Kanamycin (Kan) were obtained. PCR analysis and real time PCR detection of some transgenic plants showed that the TaNHX2 gene was evidently integrated into the genome of transgenic plants and could be transcribed properly.

Key words: TaNHX2, Albizia julibrissin, genetic transformation, Agrobacterium tumefaciens
