摘要(Abstract)：

目的:以天麻为试验材料,建立扩增酶切片段长度多态性(AFLP)分析体系。方法:对天麻DNA提取、酶切-连接、预扩增和选择性扩增等试验过程进行研究。结果:得到了清晰的天麻AFLP指纹图谱。结论:该体系具有良好的稳定性和重复性。
Objective:To establishi an amplified fragment length polymorphism(AFLP)reaction system with Gastrodia elata Blume as material.Methods:Genomic DNA of G.elata was isolated and double enzyme digestion with enzymes MseⅠand PstⅠ,adapter-ligation,pre-amplification,and selective amplification were carried out.The experimental conditions of the processes were optimized.Results:The obtained DNA fingerprints of G.elata were clear with high resolution.Conclusion:It showed that this system is stable and the experiments with the system are repeatable.
