- 摘要:
- 利用农杆菌介导法将il-4基因转入甘蓝品种“中甘11”,用已转化得到的T3、T4代甘蓝品种为试验材料,通过PCR扩增、PCR-Southern杂交、蛋白质浓度测定和ELISA技术,对il-4基因转化甘蓝的后代进行了检测,并对il-4基因在T3、T4代甘蓝中的传递规律以及后代甘蓝植株的田间表现进行了调查。结果表明:T3、T4代转il-4基因甘蓝阳性植株数较少,甘蓝中il-4基因出现性状分离。同时,田间调查表明,相对于对照组(非转基因)植株,转il-4基因阳性植株的田间抗病性下降,植株高度降低,结实率降低,单株结籽数减少,生长势等农艺性状降低。
- Abstract:
- The il-4 gene was transformed into Brassica oleracea cv.‘Zhonggan 11’ by using Agrobacterium-mediated method.The obtained T3 and T4 generation materials were detected by using PCR amplification,PCR-southern blotting,protein concentration determination and ELISA.Meanwhile the genetic rule of il-4 gene and the phenotypes of progenies were investigated.The results showed that a few positive transgenic cabbage plants were detected in T3 and T4 generation.The genetic rule of il-4 gene in transgenic cabbages didn’t according with Mendel law.Meanwhile,the field survey showed that the disease resistance,height,seed setting rate,growth potential decreased comparing to the control.
