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。
Mignon (Vigna radiata (L.) Wilczek), as a medical and dietary crop, is not only an important food resource but also plays an important role in improving the soil environment and raising the incomes of farmers. However, compared with the bulk crop, mungbean basic research is weak and genomic research lags behind. In recent years, the rapid development of molecular marker technology, mung bean genomics research has played an important role. At home and abroad using molecular markers technology has constructed more than 20 genetic linkage map of mung bean. Some excellent genes, especially those related to resistance, have been identified or finely mapped, laying a foundation for mung bean molecular marker-assisted selection and accelerating the development of new resistant varieties. In this study, the application of molecular marker technology in the construction of genetic linkage map of mungbean and the mapping of important functional genes were reviewed in this study, in order to provide reference for the research of mung bean genetic breeding and functional genomics.
