分子标记在绿豆遗传连锁图谱构建和基因定位研究中的应用

绿豆(Vigna radiata(L.)Wilczek)作为一种医食两用作物,不仅是重要的食物资源,在改善土壤环境、提高农民收入等方面也发挥着重要作用。然而,相对于大宗作物而言,绿豆基础研究薄弱,基因组研究更是落后。近年来,分子标记技术迅速发展,在绿豆基因组学研究中发挥了重要的作用。国内外利用分子标记技术已构建了超过20张绿豆遗传连锁图谱。一些优良基因尤其是与抗性相关的基因被鉴定或精细定位,为绿豆分子标记辅助选择打下基础,加快了抗性新品种的培育进程。本研究通过对分子标记技术在绿豆遗传连锁图谱构建、重要功能基因的定位等方面的应用进行综述,以期为绿豆遗传育种研究及功能基因组学分析提供参考。

Application of Molecular Marker in Study on Genetic Linkage Map Construction and Gene Mapping of Mungbean (Vigna radiata L.)

As a kind of medicinal and food crop,mungbean is not only an essential food resources,but also plays an important role in improving the environments of soils and increasing the income of farmers.However,the basic research and genomics study of mungbean is far behind the other major crops.In recent years,molecular marker technology has developed rapidly and been widely used in mungbean genome research.By using molecular markers,more than twenty sets of mung bean genetic linkage map have been constructed.Some excellent genes especially genes related to resistance were identified or fine mapped,this laid the foundation for marker-assisted selection and promoted the development of breeding for resistant cultivars.This article reviewed the application of molecular markers on genetic linkage map construction and gene mapping of mungbean.The main aim was to supply useful information for the genetic breeding research and functional genomics analysis.
