普通菜豆基因组学及抗炭疽病遗传研究进展

Current Research Progress(Phaseolus vulgaris L.)on Anthracnose Resistant Genetics and Genomics of Common Bean

普通菜豆是重要的食用豆类之一,在世界各地普遍种植。近年来,普通菜豆在遗传图谱构建、新标记开发与利用、抗性基因定位以及比较基因组学等方面取得了很大进展。遗传连锁图谱的构建是基因定位与克隆的基础,是遗传研究的重要内容;利用分子连锁图谱鉴定、标记和定位抗病基因将在种质改良和分子标记辅助育种方面发挥重要作用。豆科植物比较基因组学的研究成果为菜豆遗传连锁图谱的发展提供了新的思路。本研究从普通菜豆遗传连锁图谱的获得、普通菜豆与大豆同线性比较以及抗炭疽病基因定位等方面进行了综述,以期为普通菜豆遗传改良和抗病育种提供参考。

Common bean is one of the most important food legumes,and is grown in all parts of the world.In recent years,it has made great achievements in genetic map construction,development and utilization of new markers,resistance gene mapping and comparative genomics of common bean.Molecular linkage maps are an important tool for gene discovery and cloning.Detecting resistance gene by linkage maps can be used in marker-assistant-selecting and improvement of common bean.Legume comparative genomics research provided a new way of developping genetic linkage map.This paper gives an overview of progress of common bean genetic linkage maps,synteny mapping between common bean and soybean and gene mapping for anthracnose resistance as to provide some new reference for genome research and molecular breeding in common bean.
