The Host-Pathogen Interaction of Plasmodiophora brassicae and Canola
Research Objective
- To explore the role of clubroot's (Plasmodiophora brassicae) zoospores* to infect canola plans and cause the plant's resistance system to kick in
- The most effective way to define pathotypes** of P. brassicae and then develop tools at a molecular level to increase the speed of identifying these pathotypes
- Study transformation and/or culture of P. brassicae to facilitate research into this pathogen
Project Description
Research on the clubroot pathogen, Plasmodiophora brassicae, has knowledge gaps surrounding its genetic diversity, how the disease develops, infection processes, and the role of primary and secondary pathogen zoospores* in its disease development. This project focuses on two of these knowledge gaps, one of which is the role of primary and secondary zoospores to infect the canola plants and how they cause the plant's resistance mechanisms to be turned on. A second focus is on identifying different pathotypes ("strains") to be able to identify them and understand how they connect together. Each pathotype may require different resistance approaches, so easier identification and knowledge of the "ancestral" background of the pathotype can expedite finding a resistance strategy. Having a better understanding of clubroot in these areas will facilitate further research and development to aid canola farmers, especially in the areas of genetically resistant canola cultivars and understanding the efficiency of biological and chemical controls for the pathogen.
