Project Description
Our understanding of genetics and genomics of Leptosphaeria maculans-Brassica pathosystem has advanced rapidly in the past decade through the efforts of the international research community. However, due to the use of diverse Brassica and L. maculans genetic materials and markers, there is confusion over some of the resistance gene naming from Brassica species and their corresponding avirulence genes in L. maculans. Proper management of blackleg disease requires a clear understanding of the existing genetic capacity and pathogen virulence. In order to achieve this, we propose to coordinate the efforts of the international blackleg research community and generate a common set of plant and pathogen genetic resources and markers to be used as an international standard.
Objectives
To expand the current B. napus host differential lines
To generate a common set of L. maculans differential isolates
To genotype the R gene(s) of current B. napus collections labeled as resistant to blackleg disease
To create a common B. napus-Leptosphaeria database of genetics and genomics data as well as protocols
