| 中文摘要: |
| 对PCR呈阳性的转基因小麦植株(T0)及T1代植株接种小麦白粉病菌,鉴定结果表明:T0代接种7 d,病害表型多数为抗病;接种14 d,病害表型为抗病、中抗及中感,病害严重度明显轻于对照。T1代接种7 d后,多数表现为中抗、抗,少数为中感;接种28 d后,仅有2株仍表现抗病,其余表现为感病,但病害严重度轻于对照。对T1代植株可溶性蛋白分析表明T1代植株与对照相比多一条新谱带。 |
| 英文摘要: |
| The transgenic wheat with positive PCR results and the plants of the T1 generation were inoculated with Blumeria graminis.The results showed that the reaction type of T0 was resistant(R) in the early 7 days after inoculation,but became R,MR or MS 14 days after inoculation.Their disease severity was clearly lighter than that of the controls.Most plants of the T1 generation were MR or R,with a few as MS,7 days after inoculation.Only 2 plants were R,while others were S,in 28 days after inoculation.Their disease severity was also lighter than that of the controls.Analysis of the soluble proteins of the T1 generation indicated that T1 plants had a new band that was missing in the controls. |
