摘要:

目的:建立一种以水稻种子为原料,简便、快速、有效的基因组DNA 提取方法,作为转基因稻米的PCR 检测基础。方法:选择传统的CTAB 法、改良的碱处理法、高温水煮法,以转基因糙米、非转基因糙米、转基因精米为材料提取DNA,并对提取物进行检测。结果:改良的碱处理法提取的DNA 模板的完整性、纯度和PCR 反应方面与传统CTAB 法相近,且比CTAB 法的产率高、耗时短、成本低。结论:改良的碱处理法可以代替传统的CTAB 法用于转基因稻米检测中DNA 模板的制备。

Abstract:

Objective: To establish a simple, fast and effective DNA extraction method from transgenic rice. Methods: DNA extraction methods including traditional CTAB method, improved alkali-treated method and boiling-treated method for DNA extraction from transgenic brown rice, non-transgenic brown rice and transgenic milled rice were compared to screen the optimal extraction method. Results: The integrity, purity and PCR result of template DNA extracted by improved alkali-treated method were similar with the DNA extracted by traditional CTAB method. Meanwhile, compared with traditional CTAB method, improved alkali-treated method had higher DNA extraction rate, less consuming time and lower cost. Conclusion: Improved alkalitreated method can replace traditional CTAB method as DNA extraction method for the detection of transgenic rice.

Key words: rice, DNA extraction, improved alkali-treated method, detection of transgene
