农杆菌介导的抗菌肽基因SPCEMA对马铃薯的遗传转化
Chinese Agricultural Science Bulletin(2006)
Abstract
为了得到马铃薯抗病材料,本研究利用根癌农杆菌(Agrobacteriumtumefaciens)LBA4404转化马铃薯栽培品种“台湾红”,建立了优良的遗传转化系统:根癌农杆菌浓度以D600nm=0.5 ̄0.8为宜,感染时间以5min为宜;茎段和叶盘的预培养时间分别以4d和8d为宜,共培养时间皆以3d为宜。通过PCR和Sourhernblotting检测证明抗菌肽基因SPCEMA已成功导入其中。其茎段和叶片为的转化频率分别为10%和5.79%。
