SSR分子标记技术在植物研究中的应用

Application of SSR Molecular Marker Technique in Plant Research

SSR分子标记是目前应用较广泛的分子标记技术之一。对SSR标记的原理、特点和开发方法进行了总结,综述了SSR分子标记技术在植物DNA指纹图谱构建、遗传多样性分析、种子纯度及真伪鉴定、遗传图谱构建、分子标记辅助育种等方面的应用现状,并对目前SSR标记应用中出现的问题进行了讨论,以期为下一步开展西藏野生观赏植物资源的分子研究奠定基础。

SSR molecular markers are one of the most widely used molecular marker technologies. This paper summaized the principles,charac-teristics and development methods of SSR markers,and summarized the SSR technique in plant DNA fingpurity and authenticity identification ,genetic map construction ,molecular marker assisted breeding and other aspecttus quo,and the current application of SSR markers were discussed in order to carry out the next lay the foundation for molecular research.
