| dc.description.abstract | Bacterial Leaf streak (BLS), caused by X. translucens pv. undulosa (Xtu) is a major disease of wheat in North Dakota and surrounding areas and little is known about its local population diversity and virulence mechanisms. In my thesis research, multilocus sequence analysis and typing was used to characterize a collection of historical and contemporary worldwide Xtu strains. It was revealed that Xtu is monophyletic, and they can be grouped according to their geographic location and collection year. Additionally, targeted gene insertion mutation was used to study the role of type III effectors (Xop genes) in pathogen virulence, and two of them (XopY and XopAA) was shown to be important. In a third project, I conducted field evaluations of Hard Red Spring Wheat (HRSW) along with other commonly grown crops for their effect on the suppression of the resting spores of the canola clubroot pathogen, Plasmodiophora brassicae. It was shown that higher spore suppression was obtained for field pea and soybean than HRSW. My research provides important insights into wheat BLS pathosystem and management strategy for clubroot in North Dakota. | en_US |
