摘要: 功能标记是根据与表型紧密相关的功能基因内部特定区域的多态性序列,利用关联分析、表达谱分析、RNA干扰和QTL作图等方法开发而出的一种新型显性分子标记,此类标记可以对不同遗传背景下目标等位基因的有无作直接、快速的判定。简单介绍了功能标记的概念及特点,着重探讨功能标记作为一种辅助育种手段在小麦育种中的应用及其开发前景,以期为相关分子标记的开发提供参考。

Abstract: Based on the polymorphic sequence of a particular area in a functional gene closely related to phenotype, functional marker is a novel dominant molecular marker developed by correlation analysis, spectrum analysis, RNA interference and QTL mapping method, etc. Using these functional markers, whether or not the target allele from different genetic backgrounds exist can be directly and rapidly determined. In this work, the concept and characteristics of functional markers are briefly introduced, mainly exploring the application and prospect of functional markers as an assistant means in wheat breeding, in order to provide reference for the development of related molecular markers

Key words: wheat, molecular marker, functional gene, assistant breeding
