SSR vs ISSR：有何差异？ ### SSR标记：微卫星DNA的秘密 SSR标记，全称简单重复序列标记，是分析那些含有1-6个核苷酸重复序列的DNA区域的分子标记。简单来说，它是一种微卫星DNA，属于VNTR（可变数量串联重复）的一种。SSR标记的重要性在于它们能揭示遗传结构的复杂性。因为SSR标记是共显性的，所以它们能识别杂合位点。此外，这些标记还能鉴定多等位基因性质，同时鉴定多个等位基因，具有可重复性、高多态性和基因组的均匀分布。微卫星DNA，也就是我们常说的STR（短串联重复序列），在基因组中出现了数千次。SSR标记的核苷酸序列放大了这些串联核苷酸重复。简单来说，它们通过扩增串联重复来识别杂合位点。 ISSR标记：显性DNA序列的魅力 ISSR标记则是另一种包含显性DNA序列的DNA标记。这些标记的重复序列长约100-300个核苷酸。ISSR标记通过使用引物扩增，引物退火到基因组中两个相邻微卫星区域的互补序列。因此，它允许在单个实验中分析多个位点。然而，ISSR标记出现在两个微卫星重复序列之间。因此，ISSR标记允许扩增基因组中的随机DNA序列。由于ISSR标记是显性DNA序列，因此只能检查DNA序列的存在与否。这对于鉴定品种的遗传变异非常重要。总结：SSR和ISSR的主要区别简而言之，SSR和ISSR标记是两种对群体表征非常重要的遗传标记。SSR标记出现在微卫星中，它们有1-6个核苷酸重复序列。它们通过扩增串联重复来识别杂合位点。另一方面，ISSR标记是发生在微卫星DNA之间的基因组DNA序列。它们是100-300个核苷酸的较长重复序列。ISSR标志物允许在单个实验中分析多个位点。此外，它们扩增基因组的随机序列。因此，SSR 和 ISSR 标记之间的主要区别在于重复的类型。
