- 摘要:
- 以哈密大枣无菌苗叶片为试材,以根癌农杆菌LBA4404为媒介将抗寒基因转录因子CBF基因导入哈密大枣,利用PCR、RT-PCR对转化植株进行鉴定,建立了哈密大枣的遗传转化体系。结果表明:在对哈密大枣无菌苗叶片进行遗传转化时,预培养2 d,农杆菌菌液OD600为05,浸染20 min,共培养3 d的转化效率为最高。试验共获得7个抗性再生转化系。经PCR鉴定,CBF基因在7个抗性再生转化系中均为阳性;经RT-PCR分析,CBF基因在7个抗性再生转化系中均得到表达。
- Abstract:
- Hami Zizyphus jujuba leaves were used as test materials to study genetic transformation of Hami Zizyphus jujuba by using CBF transcription factor of antifreeze gene,the CBF transcription factor of antifreeze gene was induced by using Agrobacterium tumefactions LBA4404,the transgenic plants were identified by using PCR and RT-PCR.The results showed that the highest transformation efficiency was obtained when leaf explants were cultured 3 days after pre-cultured for 2 days and infested for 20 minutes with Agrobacterium tumefactions (OD600=05).7 resistance regenerated transformation systems were obtained in this experiment.CBF genes were positive by using PCR identify and expressed by using RT-PCR analysis in 7 resistance regenerated transformation systems.
