摘要: 以桦树(Betula)DNA为材料,分析了DNA浓度、TagDNA聚合酶用量及退火温度对ISSR-PCR扩增结果的影响,筛选出了扩增条带清晰、多态性丰富的17个ISSR引物,建立了稳定的、可重复的桦树ISSR-PCR最佳反应体系及PCR扩增参数,为今后利用ISSR标记技术开展桦树种间遗传多样性分析提供一个标准化程序

Abstract: In this paper,the influence of DNA concentration, Tag DNA polymerase and annealing temperature on the result of ISSR-PCR amplification was analyzed using the materials of birch DNA. Seventeen primers, which produced clear and rich polymorphism bands, were screened. The stable and reproducible optimum reaction system of ISSR PCR and PCR amplification parameter were established for birch. The result provided a standardizing program for the analysis of interspecies genetic diversity of Birch.
