Research Project: **Location:
                            Cereal Disease Lab** Project Number: 5062-21220-025-003-S
                        
                        Project Type: Non-Assistance Cooperative Agreement Start Date: Jul 1, 2019
                        
                        End Date: Jun 30, 2024 **Objective:**
                        
                        The ultimate objective of project is to enhance resistance of oat cultivars to crown rust pathogen. **Approach:**
                        
                        Rust resistant oat germplasm (wild species and cultivars) will be systematically selected by screening various sources in the buckthorn nursery where a large and variable source of pathogen is maintained.  Testing with selected isolates of the crown rust pathogen and or mixture of variable population collected from buckthorn, and host genetics studies will identify the rust resistance genes in these germplasm. These genes will then be introgressed into modern cultivars and lines with combinations of rust resistance genes will be selected and released for further use in cultivar development. Rust fungi produce a large arsenal of effector proteins in order to infect and colonize the plant host. Genetic and genomic approaches will be used to identify and characterize effector genes from P. coronata.
