Project Description
The pathogen (P. brassicae) populations in western Canada are evolving rapidly. It is extremely important to have canola cultivars with new sources of resistance available to Saskatchewan canola producers. The availability of new resistance genes and new CRISPR/Cas9 methods for B. napus will enable canola breeders to incorporate any genes desirable from exotic germplasm rapidly and without linkage drag. As such, the cost for introgressing genes from exotic germplasm into spring canola could be dramatically reduced in the future by technologies developed in the project. In addition, cloning of clubroot resistance genes could lead to molecular characterization of these genes and the pathogen effector genes that interact with them which could support a better understanding of CR resistance for long-term clubroot control.
Objectives
Identify the most probable candidates for the CR genes identified in B. nigra.
Isolate candidate genes from B. nigra.
Deliver the candidate genes into canola using a newly established CRISPR/Cas9 based system.
