Blackleg resistance gene

Detailed Technology Description

The purpose of this invention is to control blackleg disease in Brassica napus canola/rapeseed. This disease caused by Leptosphaeria maculans is one of the most serious diseases in canola/rapeseed production globally. The most effective method to control this disease in canola/rapeseed is to develop blackleg disease resistant cultivars.The problem this invention solves is knowledge of the gene underlying resistance. Using a known blackleg resistance gene leads to the effective and efficient development of new B. napus canola/rapeseed cultivars with strong and durable blackleg disease resistance. In this patent, the cloning and functional confirmation of a blackleg disease gene is described and the sequence including the structural disease resistance gene and its functional promoter region and downstream region is included. The function of the disease resistance gene was definitively confirmed through complementary plant transformation. This blackleg disease resistance gene can be used in conventional breeding through marker assisted selection or through the introduction of the blackleg resistance gene by plant transformation. Additionally, the sequence of this blackleg resistance gene makes it possible to search other homologous disease resistance genes in different Brassica species.
