马铃薯晚疫病抗病基因研究进展

Research Progress of Late Blight Resistance Genes in Potato

晚疫病是危害马铃薯生产的重要病害,可导致马铃薯的大量减产。多年来研究人员对马铃薯晚疫病进行了大量的研究,取得了一系列的成果。对马铃薯晚疫病防治最有效的方法是使用抗病品种,随着分子生物学技术的发展,从野生资源中分离抗病基因,并将其转入到栽培种马铃薯中可以获得抗病特性。到目前为止,已经有十多个抗晚疫病基因被发现和图谱,且部分基因已被转入到栽培品种中。本文从晚疫病抗病基因的发现、分离、定位及克隆等方面进行了综述。

Late blight is one of the most devastating diseases in potato.It can lead to a great loss in the yield and quality.The researchers have made intensively studies on late blight.And they have acquired many results in the past years.The use of resistant varieties was considered to be the most sustainable approach for the management of late blight.With the development of the molecular biology technology,isolation of the genes that code for the resistance traits found in wild sources and subsequent transformation of existing potato cultivars with these genes could be means of exploiting potentially durable late blight resistance in wild Solanum species.Up to now,more than ten late blight resistance genes have been detected and mapped from wild sources and some of them have been introduced into varieties.This paper summarized and described the research state of late blight genes in potato.
